MoCA vs. DOCSIS 3.1: Whose Spectrum Is It? OFDM and profiles are much more complex than we can describe in a single blog post. Its main advantage lies in its range and data transmission rate. The latest version, DOCSIS 3.1, allows up to 10Gbps downstream and 1Gbps upstream, which to-date had only been possible with a fiber optic connection, and can, with few infrastructural changes, be easily deployed over existing infrastructure. The hybrid fiber/coax (HFC) network architecture, used by broadband cable in conjunction with Data Over Cable Service Interface Specification (DOCSIS), has many years of useful service left. But in the case of fiber, you don’t need Docsis 3.1 as fiber internet only works with fiber optic specific modems. [1] https://www.cablelabs.com/technologies/docsis-4-0-technology, [2] https://www.cablelabs.com/technologies/docsis-3-1. In a more typical situation where multiple QAMs are being used at the same time, DOCSIS 3.1 is still able to achieve 8.5 bits/Hz – making it 35% more efficient without changing the HFC plant. Cost: DOCSIS wins 3. [2] The biggest expense with fiber is running the subscriber drop. First, GPON is delivered over a fiber connection right up to the residence. Fiber; WiFi Boosters; Blog; Support; Select Page. Nor had Gigabit Ethernet, or “Gig-E,” gained such dominance in metropolitan and wide area networks as a remarkably cheap, fast way to move data over fiber. Q: Is a Docsis 3.1 modem worth it? It is a DOCSIS 3.0 modem with an inbuilt AC1600 dual-band Wi-Fi router. Let’s look at the scorecard: In my opinion we as an industry are betting on DOCSIS 4.0 for only one reason — cost. Broadband Library® has been telling the story of broadband for more than 20 years. If we take those out (since DOCSIS network upgrades will happen anyway for residential broadband services) the TCO of these indoor use cases get even better compared to the fiber outdoor case (scenario 1). DOCSIS 3.1. It boils down to this: When DOCSIS was created, Ethernet didn’t have many of the “convergence-friendly” attributes it has now. DOCSIS lies between these 2, as it is faster than DSL but slower than Fiber technology. And Docsis 3.1 is a new generation of technology made for high-speed connections. First, let’s clarify that it is NOT FTTH vs. DOCSIS 3.1. To us, it was always a no-brainer that a DOCSIS network-based deployment would have favorable economics compared to a fiber-based model. However, it does not support cable digital voice service. One application where I absolutely see the difference in DOCSIS vs. Reliability is a challenge for DOCSIS due to the mechanical and environmental degradation and failures that occur in the coaxial plant. FTTH is a Point to MultiPoint (P2MP) network architecture, DOCSIS 3.1 is a transport mechanism. Other technologies such as proactive network maintenance (PNM) and Low Latency DOCSIS will continue to improve reliability and latency.” It pays to think of FTTH and HFC as different tools in the same box. On fiber … Fiber, on the other hand, can be deployed with 10 Gbps small form-factor pluggable (SFPs) on a single wavelength. DOCSIS x.x is MOCA or Coax. DOCSIS 3.1 is the current modem technology. Stay SAFE! The creation of DOCSIS 3.1 has made this choice more difficult because DOCSIS 3.1 enables 10 … This often translates directly into more satisfied customers. DOCSIS 3.1, DOCSIS 4.0, point-to-point coherent optics, PON, and advanced wireless technologies will all enable 10G speeds. DOCSIS 3.1 uses frequencies up to 1.2 gigahertz, but common fiber-optic cables carry light in the infrared spectrum between 200 and 350 terahertz. Absolutely not. The original question was can DOCSIS 3.1 or even future versions of DOCSIS compete with fiber? and they offer gigabit speeds @ 1/10gigabits? The benefit with coax is that it is already there, passing more than 90% of the homes in the U.S. This is the dream of every home. This question may be in your head when building innovative networks and providing the best service to your customers. Data-Over-Cable Service Interface Specifications (DOCSIS) was already in development which enabled the cable industry to provide high speed data and later voice-over-Internet protocol (VoIP). docsis 3.1 vs fiber? Before a cable company can deploy DOCSIS 1.1 or above, it must upgrade its hybrid fiber-coaxial (HFC) network to support a return path for upstream traffic. Once upgrades are made, DOCSIS 3.1 will give providers speeds that can compete with fiber. FTTH is a Point to MultiPoint (P2MP) network architecture, DOCSIS 3.1 is a transport mechanism. From the technical side, let’s look at the raw capability of fiber and today’s DOCSIS 4.0 technologies. The main take away is that DOCSIS no longer needs to be optimized for the worst part of the plant. FTTH is a Point to MultiPoint (P2MP) network architecture, DOCSIS 3.1 is a transport mechanism. For EuroDOCSIS it’s 6.952 Msym/s for both 64-QAM and 256-QAM. Pingback: DOCSIS 4.0 | Providing 10 Gbps pipe at the right cost. It has been over a 20-year competition between telecom and cable operators, one that the cable industry has done quite well with and the telecom industry has struggled to keep up. Coax was installed and designed to deliver TV. This can give providers some time to make those upgrades, while increasing quality of experience for their customers in the near term. DOCSIS question to a dozen or so smart, tech-side people. Further, if there are fewer problems with a fiber network the end user or subscriber is less likely to experience problems due to plant impairments. DOCSIS 4.0 was designed to hit downstream speeds of up to 10 Gbps, which is twice the download speed of DOCSIS 3.1, and an upstream of up to 6 Gbps (quadruple the DOCSIS … Fiber is able to transport more data at higher speeds than cable, but completely replacing a cable network with fiber is cost prohibitive. As a result of this, the raw downstream bitrate of one 256-QAM downstream channel is about 42.88 Mbps for DOCSIS vs. 55.62 Mbps for EuroDOCSIS. The best DOCSIS 3.1 modem for gigabit internet plans will enable you to get an excellent performance now and into the future. Should we therefore abandon DOCSIS? The cost to install new fiber is on parity with coax. I have some NTP associations from my house to a server in a datacenter. It allowed cable and telecom to directly compete with each other. Fiber is practical and preferable in many cases, especially when considering one of the great benefits of DOCSIS 3.1 is that it works over both coaxial and fiber networks. But in the case of fiber, you don’t need Docsis 3.1 as fiber internet only works with fiber optic specific modems. DOCSIS 3.1 has ten times more speed than DOCSIS 3.0. It’s not self-healing. It is something that you can rent from your ISP but you can also buy your own. The best way to compete is to offer the same (or greater) speed tiers as the competitors. The original question was can DOCSIS 3.1 or even future versions of DOCSIS compete with fiber? 6001 America Center Drive, 6th Floor, San Jose, CA 95002. Cable providers have spent years trying to solve a dilemma: “Do we spend money to completely upgrade the plant or do we make due with incremental improvements to our existing plant?”. Should we therefore abandon DOCSIS? Fiber is able to transport more data at higher speeds than cable, but completely replacing a cable network with fiber is cost prohibitive. OFDM is able to use the highest QAM possible that any specific part of the plant can handle at any given point in time for each of the subcarriers. So I got some industry intel to help me better understand the differences. Running at peak performance, DOCSIS 3.1 has the ability to provide 10 G on the downstream and 2 G on the upstream – speeds that can rival fiber. Cost of deployment is where coax has a huge advantage over fiber. Fiber may be faster, but it is available only in limited areas, and DSL may be having range, but it is often quite slow. VIAVI Perspectives offers a view of timely industry trends, innovations and breaking news from Viavi bloggers and leaders. Marketing is the great intangible, which I have written about in previous Broadband Library articles. DOCSIS 3.1 vs Fiber Prior to DOCSIS 3.1, Fiber to the Home (FTTH) was the only available option for consumers seeking the highest order of data transmission speeds. Evolve or Die: Can DOCSIS 4.0 Compete with Fiber? 35 A typical fiber-optic cable has around 10,000 times more usable bandwidth than a typical coaxial cable. Q: Is a Docsis 3.1 modem worth it?

. It would bankrupt most if not all cable operators. Once upon a time, when DOCSIS was created, it had one mission: To move IP data over cable’s hybrid-fiber coax (HFC) networks. © Copyright 2018 Lundwall Communications, Inc. All Rights Reserved. Comparisons of FTTH and DOCSIS (.pdf) usually aren't very thorough. 100 Gbps is generally implemented as 10×10 Gbps on 10 “channels” or different wavelengths of light. DOCSIS 3.1 is expected bring many things to the cable operator's table, including increased capacity and more robust modulation. Faster speeds, better service, less cost and 10G sound great. Each profile adjusts the modulations of the subcarriers for different signal to noise conditions. Expect to see commentary, videos and visuals on topics about the network, mobility, the Enterprise and more. Other technologies such as proactive network maintenance (PNM) and Low Latency DOCSIS will continue to improve reliability and latency.” It pays to think of FTTH and HFC as different tools in the same box. If your ISP offers internet packages of over 1Gbps, then a Docsis router a worthy investment for you. He is a highly respected published speaker, both domestically and internationally. Until now, providers have added fiber to new parts of the plant and tried to make the most of DOCSIS over existing cable networks. Physics: Fiber wins 2. Until now, providers have added fiber to new parts of the plant and tried to make the most of DOCSIS over existing cable networks. It is very tough to win a marketing war against raw speed. He also hosts a popular industry YouTube and Podcast – “Get Your Tech On“. DOCSIS 3.1 vs Fiber Prior to DOCSIS 3.1, Fiber to the Home (FTTH) was the only available option for consumers seeking the highest order of data transmission speeds. If there is some noise in another part of the plant, a lower profile (and modulation) would be used in that part of the plant such as 1024 QAM. DOCSIS 3.1 Modem vs 3.0 Speeds and Testing. DOCSIS 3.1 is expected bring many things to the cable operator's table, including increased capacity and more robust modulation. In this TCO analysis, we showed >50% reduction in TCO for an outdoor use case of backhauling small cells when served by DOCSIS networks compared to a more traditional deployment served by fiber. Let’s look at the scorecard: 1. Mr. Volpe holds a MSEE and a BSEE. In general, there have been three different major iterations of DOCSIS over the years; 1.x, 2.x, and 3.x. Before a cable company can deploy DOCSIS 1.1 or above, it must upgrade its hybrid fiber-coaxial (HFC) network to support a return path for upstream traffic. If your ISP offers internet packages of over 1Gbps, then a Docsis router a worthy investment for you. Thread starter warm; Start date Feb 21, 2016; Tags docsis 3.1 Feb 21, 2016 #1 W. warm n00b. Without a return path, the old DOCSIS 1.0 standard still allows use of data over cable system, by implementing the … A modem is a device that communicates with your Internet service provider (ISP) to connect you to the Internet. So, DOCSIS provides the best of both worlds to the user. My point is that it’s important that we understand what we are up against and not put blinders on. At the recent CableLabs Winter Conference, CableLabs unveiled Full Duplex DOCSIS technology, which offers the promise of symmetrical 10 Gbps on 1 GHz HFC networks. And what major changes need to be made to take advantage of OFDM? This would give us: That exceeds our 10G initiatives. DOCSIS 3.1, DOCSIS 4.0, point-to-point coherent optics, PON, and advanced wireless technologies will all enable 10G speeds. He has over 25 years of broadband cable and telecommunications industry experience specializing in RF, DOCSIS, PNM, and Internet Protocol. These delights, however, are being served alongside a host of challenges and complex puzzles that need to be solved in order to ensure a positive customer experience. G.PON and N.GPON 2 offer OSS supporting DOCSIS provisioning (Open Link Cable) and vendors like Calix offer sealed OLTs, powered via Coax for distributed outdoor deployments allowing replacements of micro … DOCSIS includes security features to prevent interception or alteration of Ethernet data. In this TCO analysis, we showed >50% reduction in TCO for an outdoor use case of backhauling small cells when served by DOCSIS networks compared to a more traditional deployment served by fiber. Be it aerial or buried, there is a lot involved with permits, trenching, not to mention the headaches of tearing up people’s lawns. The question for cable operators that already have HFC networks is how to know when they should invest in the current HFC network vs. deploying fiber all the way to the home. Docsis means Data Over Cable Service Interface Specification. The symbol rate for US DOCSIS is 5.056941 megasymbols per second (Msym/s) for 64-QAM and 5.360537 Msym/s for 256-QAM. The fiber nodes are connected to a distribution hub using a single fiber for the upstream and a single fiber for the downstream. If you look at fiber objectively from any other perspective it outperforms DOCSIS. DOCSIS 3.1 is the current modem technology. i'm still not sure if i understand the concept of docsis 3.1, technically docsis 3.1 is just replacing the box/modems on both sides with the same cooper cable/lines connected right? It offers faster downloads speeds on the coaxial cable as compared to fiber cable. What are the benefits of DOCSIS 3.1? So, if you are in the market to buy a new modem, then why not buy a modem that is future proof. – How Leakage Technologies Can Protect Your Network Heroes, The future and ecosystem of an all-optical network, “The Many Paths to 400G” from Gazettabyte, SUNBURST and the importance of evidence-based risk management, VPN testing: it’s never been more important and it’s never too late, How Fiber Optics Supports Cloud Technology, Keeping the marketing wheel moving in APAC. The combination is an efficient and cheap way to bring locations together in an SD-WAN. Providers will need to make some upgrades to their networks to reach the highest levels of performance, but because of the inherent capabilities of OFDM, DOCSIS 3.1 provides immediate performance enhancements. So, first of all, let’s clarify that this should not be a question of FTTH – Fiber To The Home vs. DOCSIS 3.1 Cable Technology. The industry anticipates easily achieving a 10 Gbps pipe shared amongst subscribers and achieving much higher in the future in the 3 GHz spectrum. For a quick overview of how DOCSIS 3.1 works, this infographic is a great place to start. Absolutely not. In the past, DOCSIS speeds have been slow compared to pure Ethernet speeds. One of the best aspects of OFDM is that providers can immediately take advantage of speed and throughput increases without making major upgrades to existing networks. Brady Volpe is Founder of The Volpe Firm, Inc and Nimble This LLC. DOCSIS 3.1 Modem vs 3.0 Speeds and Testing Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard for the addition of high-bandwidth data transfer to an existing coaxial cable TV system. Where DOCSIS 3.0 was able to achieve 6.3 max bits/Hz, DOCSIS 3.1 is able to achieve 10.5 max bit/Hz at 4096 QAM. If you look at fiber objectively from any other perspective it outperforms DOCSIS. For new builds or upgrades to older Docsis installations, fiber, especially PON which mirrors HFC deployments (topology wise) is a more future proof and less OPEX intensive solution. It is a standard for transferring data over the cable system. In case you decide to switch from Xfinity in the future, you should note that this modem is also not compatible with AT&T, Century, or other DSL and Fiber internet service providers. Mr. Volpe has been providing a wide range of troubleshooting, design solutions, services and seminars for cable operators and broadband companies specializing in DOCSIS, System Design, PNM, and Troubleshooting. DOCSIS 4.0 unifies previously feuding Full Duplex DOCSIS and Extended Spectrum DOCSIS proposals for boosting network bandwidth. Data Over Cable Service Interface Specification (DOCSIS) is a long way to say “how cable Internet works.” DOCSIS 1.0 was developed by Cable Labs in 1997, and it’s been under development since, getting faster and more power-efficient with each incarnation.. It would bankrupt most if not all cable o… — However, with just plain facts fiber wins in reliability. Let us know in the comments below. This is the key differentiator for DOCSIS technology vs. fiber, where most of the backhaul connections require either new build or premium lease rates. Check out past issues of the award-winning Broadband Library! Broadband Library is an exclusive member-benefit of the Society of Cable Telecommunications Engineers (SCTE) and its global brand, the International Society of Broadband Experts™ (ISBE). Over the years, as bandwidth demand grew, DOCSIS answered the call by enabling fiber-like Gigabit per second capacity. The Main Differences. I have some NTP associations from my house to a server in a datacenter. Today we are looking to extend the RF range of coax cable up to 1.8 GHz (investigation for up to 3 GHz is underway for even more capacity!). o DOCSIS 1.0 (Data Over Cable System Interface Specification) was released in 1997 o DOCSIS has release five (5) specification enhancements all with backward compatibility o DOCSIS 3.1 offers multiple Gbps data rates capacity / speed varies based on spectrum allocation FTTH (Fiber to the Home) If so, what are the main questions you have concerning OFDM and profiles? Without a return path, the old DOCSIS 1.0 standard still allows use of data over cable system, by implementing the … MoCA vs. DOCSIS 3.1: Whose Spectrum Is It? [1] DOCSIS 4.0 supports a downstream throughput with 4096-QAM and 25 kHz subcarrier spacing of up to 1.89 Gbps per 192 MHz OFDM channel. This is the dream of every home. What are the benefits of DOCSIS 3.1? 6500 Reconfigurable Line System. Your email address will not be published. Marketing: It’s a tie provided DOCSIS 3.1 or 4.0 are deployed In my opinion we as an industry are betting on DOCSIS 4.0 for only one reason — cost. o DOCSIS 1.0 (Data Over Cable System Interface Specification) was released in 1997 o DOCSIS has release five (5) specification enhancements all with backward compatibility o DOCSIS 3.1 offers multiple Gbps data rates capacity / speed varies based on spectrum allocation FTTH (Fiber to the Home) It can support data transfer up to 10 gigabits per second downstream and 1 gigabit per second upstream over cable, which was only possible over the fiber-optic network. The question we face is will DOCSIS 4.0 and future versions of DOCSIS enable us to keep up with the telecom industry’s focus on fiber deep deployment? DOCSIS has become one of the key elements helping cable operators dominate broadband services. Studies have shown that fiber costs five times less per mile than coax to maintain. As fiber networks continued to propagate between source and user, the install base of fiber and ultimately the elimination of coaxial cable in favor of fiber seemed like a forgone conclusion. Although OFDM is much more complex that this, the main point is that OFDM can change the profiles in real-time to optimize modulations to the best parts of the plant – dramatically increasing speed and throughput. docsis 3.1 vs fiber? DOCSIS 3.1—which includes LDPC encoding, very high modulation orders (e.g., 4096 QAM), more than 1 GHz of usable spectrum and support of QoS and low latencies—is the latest digital communications technology, but it's not a replacement for your existing hybrid fiber coax (HFC) architecture that uses coaxial cable to connect to homes. DOCSIS 4.0 enables this competition by providing a 10 Gbps pipe. This is the key differentiator for DOCSIS technology vs. fiber, where most of the backhaul connections require either new build or premium lease rates. DOCSIS 3.1, released in 2013, closes the gap. The question for cable operators that already have HFC networks is how to know when they should invest in the current HFC network vs. deploying fiber all the way to the home. Cable throughput speeds have traditionally been lower than fiber options, although DOCSIS 3.0 enables 1 Gbps download speeds (but this is not a symmetrical connection as … market. Any estimates of cost per sub to upgrade to Docsis 3.1? We allocated 20% of DOCSIS network upgrade (from low split to mid split) cost to DOCSIS network-based use cases (scenarios 2 and 3). But switching over to DOCSIS 3.1 is a lot more affordable on the ISP’s end compared to building a new network of fiber-optic lines—it’s like installing new tires for a car versus building an entirely new car from scratch. The Telecommunications Act of 1996 forever changed the cable industry. With the DOCSIS 3.1 deployments starting to roll out, the cable industry is, of course, thinking about what comes next. The creation of DOCSIS 3.1 has made this choice more difficult because DOCSIS 3.1 enables 10 Gbps services to the home over HFC networks. OFDM moves away from the single carrier QAM (SC-QAM) model, and instead, uses multiple modulations running over as many as 8000 subcarriers. However, it does not support cable digital voice service. Your email address will not be published. In general, there have been three different major iterations of DOCSIS over the years; 1.x, 2.x, and 3.x. Data Over Cable Service Interface Specification (DOCSIS) is a long way to say “how cable Internet works.” DOCSIS 1.0 was developed by Cable Labs in 1997, and it’s been under development since, getting faster and more power-efficient with each incarnation.. One application where I absolutely see the difference in DOCSIS vs. Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard for the addition of high-bandwidth data transfer to an existing coaxial cable TV system. Furthermore, fiber-optic cables are much less susceptible to interference and noise than coax or wireless channels. If one part of the plant is clean, a higher profile (and modulation) would be used such as 4096 QAM. With the introduction of DOCSIS 3.1, this all changes. It is important to understand the differences so that you are informed before renting or buying your own modem. Fiber is NTP. CableLabs said the raw speeds enabled by DOCSIS 4.0 on widely deployed hybrid fiber/coax (HFC) networks represent a doubling of the max downstream available via DOCSIS … Do NOT follow this link or you will be banned from the site. OFDM makes quantum leaps in the amount of data capacity and speed available – sometimes as much as 50 percent more capacity over the same spectrum. Fiber, and specifically GPON, has fewer moving parts than DOCSIS or RFoG. By design, HFC networks deliver sharable bandwidth to pockets of 500-ish homes. — Fiber is the winner from a pure physics standpoint as it is inherently easier to provide higher bandwidths in fiber. Fiber is NTP. It offers faster downloads speeds on the coaxial cable as compared to fiber cable. For example, each of the profiles are assigned a letter such as A, B, C, D and so on. This falls under the terminology of extended spectrum DOCSIS (ESD) in the DOCSIS 4.0 specification. One of the main changes to DOCSIS 3.1 is orthogonal frequency domain multiplexing (OFDM). GPON vs. DOCSIS 3.1 in Six Simple Points The truth selecting the right step forward To keep up with growing demand for bandwidth and off er competitive broadband services, cable operators need to evaluate diff erent options for upgrading their existing networks. In typical deployments we can fit six OFDM channels in ESD. Are you planning to deploy DOCSIS 3.1 into your network? DOCSIS is delivered on coaxial cable. It is a DOCSIS 3.0 modem with an inbuilt AC1600 dual-band Wi-Fi … These delights, however, are being served alongside a host of challenges and complex puzzles that need to be solved in order to ensure a positive customer experience. So I got some industry intel to help me better understand the differences. There are a few different types of modems. One of the other essential facts about DOCSIS 3.1 is that it is backward compatible. Even if we don’t know what we will do with a 1 Gbps Internet connection most will surely take it if it is offered. The middle is DOCSIS. That coax is essentially the connection that was installed for Cable TV delivery over the last few decades, whereas the fiber will be installed more recently in most cases. But how is this possible? GPON vs. DOCSIS 3.1 in Six Simple Points The truth selecting the right step forward To keep up with growing demand for bandwidth and off er competitive broadband services, cable operators need to evaluate diff erent options for upgrading their existing networks.

Reliability: Fiber wins 4. For more in depth information, see the white paper “DOCSIS 3.1: Best Practices for Peak Performance”. The limited speeds are because not everyone has adapted to DOCSIS 3.1. On fiber … That is 10 times more capacity than DOCSIS 4.0 and it exists today. To make the latest gigabit fiber internet to work, you need a DOCSIS 3.1 gigabit cable modem. Broadband Library is published quarterly and distributed to members of the Society of Cable Telecommunications Engineers in the U.S. CPM # 40065056 Printed in U.S.A. If your ISP doesn’t support Docsis 3.0, you’ll also find the Docsis 3.1 modem as the only cable modem option available for you. First, let’s clarify that it is NOT FTTH vs. DOCSIS 3.1. In case you decide to switch from Xfinity in the future, you should note that this modem is also not compatible with AT&T, Century, or other DSL and Fiber internet service providers. Both cable operators and telecom operators can deploy fiber and are doing so today. Without getting too far into the mud of data networking, here’s what they had to say. Joined Apr 20, 2013 Messages 16. i'm still not sure if i understand the concept of docsis 3.1, technically docsis 3.1 is just replacing the box/modems on both sides with the same cooper cable/lines connected right?
