Without a return path, the old DOCSIS 1.0 â¦ Brady Volpe is Founder of The Volpe Firm, Inc and Nimble This LLC. Experts say main benefits of FTTH is increased network performance, specifically higher speeds over a long distance, which the older method of using coaxial cables, twisted pair conductors and DSL cannot reach. ... Make sure to choose a DOCSIS 3.0 or 3.1 â¦ Cost: DOCSIS wins 3. On the other hand, FTTH – Fiber To The Home, also called Fiber To The Premises (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartments and businesses to provide high-speed internet access. He has over 25 years of broadband cable and telecommunications industry experience specializing in RF, DOCSIS, PNM, and Internet Protocol. 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). But you will not go wrong if you choose another option…. Is 2021 the year of digital transformation in telecom industry? The benefit with coax is that it is already there, passing more than 90% of the homes in the U.S. Should I go for FTTH or DOCSIS? Marketing: Itâs 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 â cost. It allowed cable and telecom to directly compete with each other. The original question was can DOCSIS 3.1 or even future versions of DOCSIS compete with fiber? Your email address will not be published. Should we therefore abandon DOCSIS? But, although a lot is possible regarding speed and capacity when it comes to DOCSIS 3.1, in the end, results depend mainly on how much money has been invested. Fiber allows for significantly faster transmission speeds, so has transformed data, video and voice services. The first release goes back to October 2013, although this technology was updated several times since. cost per capacity) is lower for GPON than it is for DOCSIS 3.x. Both cable operators and telecom operators can deploy fiber and are doing so today. FTTH vs DOCSIS (II): The future of Gigabit capable technologies. To us, it was always a no-brainer that a DOCSIS network-based deployment would have favorable economics compared to a fiber-based model. In typical deployments we can fit six OFDM channels in ESD. To clarify even more, Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that allows the addition of high-bandwidth data transfer to an existing cable television system. What are the benefits of DOCSIS 3.1? Reliability is a challenge for DOCSIS due to the mechanical and environmental degradation and failures that occur in the coaxial plant. However, gigabit service over a fiber â¦ Evolve or Die: Can DOCSIS 4.0 Compete with Fiber? Sell on twoosk So, the question to be made is “what architecture is needed, and which transport technologies works over that architecture?” DOCSIS 3.1 could make sense for operators facing some particularities like bandwidth competition with limited capital, the necessity of delivering higher speeds while delaying the more expensive FTTH transition, among many others. Same is to say that FTTH promises connection speeds of up to 100 megabits per second, being that 20 to 100 times as fast as a typical cable modem or DSL connections. Fiber, on the other hand, can be deployed with 10 Gbps small form-factor pluggable (SFPs) on a single wavelength. Pingback: DOCSIS 4.0 | Providing 10 Gbps pipe at the right cost. Absolutely not. If you look at fiber objectively from any other perspective it outperforms DOCSIS. Letâs look at the scorecard: In my opinion we as an industry are betting on DOCSIS 4.0 for only one reason â cost. The debate over the best infrastructure to deliver fixed last-mile broadband service in the 21st century is settled, and fiber is the undisputed winner. 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. Be it aerial or buried, there is a lot involved with permits, trenching, not to mention the headaches of tearing up peopleâs lawns. The cost to install new fiber is on parity with coax. Fiber is a common upgrade choice from DSL, particularly in larger cities. 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. Data Over Cable Service Interface Specification (DOCSIS) is a long way to say âhow cable Internet works.â DOCSIS 1.0 was developed by Cable Labs in 1997, and itâs been under development since, getting faster and more power-efficient with each incarnation.. One or more Ethernet Virtual Connections (EVC) can be set up between two remote locations. Through a SW upgrade, some CMTSs can offer partial DOCSIS 3.1 support, still better than DOCSIS 3.0. DOCSIS 3.0's highest possible speed is 1Gbps, also known as âGigabit internet." Again, most homes already have the coax drop in place. In some cases, DOCSIS over a glass architecture is, for sure, a perfect option for delivering broadband services to homes over fiber. The creation of DOCSIS 3.1 has made this choice more difficult because DOCSIS â¦ In eï¬ ect, the throughput of GPON is less expensive than the throughput of DOCSIS â¦ Buy on Twoosk 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 the upload â¦ A modem is a device that communicates with your Internet service provider (ISP) to connect you to the Internet. Most home Internet service delivers faster speeds for downloading vs. uploading, due to average consumer needs. Letâs look at the scorecard: 1. â DOCSIS remains the clear winner here. Fiber Optic is Faster: If you compare FTTH (Fiber to the Home) service to cable broadband, the FTTH can reach up to Gbps of speed while the cable broadband is generally maxed at 300 Mbps. There are pros and cons to both options. Cost of deployment is where coax has a huge advantage over fiber. 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. 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. Fiber-to-the-home deployments are a better option for consumers today, and they are the only option that will allow expansive, efficient upgrades to Americaâs networks for a generation.

Should operators skip DOCSIS 3.1 and pursue FTTH? DOCSIS is delivered on coaxial cable. The question we face is will DOCSIS 4.0 and future versions of DOCSIS enable us to keep up with the telecom industryâs focus on fiber deep deployment? Help [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. cm8200 vs sb8200. Note that even Cat 6 cables can provide up to 1 Gbps of speed, but the ISPs user Fiber â¦ DOCSIS 3.1 has arrived, and itâs a gamechanger. This is the key differentiator for DOCSIS technology vs. fiber, where most of the backhaul connections require either new build or premium lease rates. One has to choose according to the demands of the business and what the company is dealing with. My point is that it’s important that we understand what we are up against and not put blinders on. As you can see by now, there is not a right or wrong for this kind of technology. Or is the other way around? 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 3.1 is the current modem technology. DOCSIS 3.1 technology also includes some new energy management features that help the cable industry to reduce its energy usage, and the DOCSIS-PIE algorithm to reduce buffer bloat. Fiber is the best choice for most customers, as it provides high-bandwidth connections up to 1,000 Mbps download and upload speed. If you are a cable player, so DOCSIS 3.1 can be a game-changer, maximizing both the upstream and downstream throughput in the network, without expensive changes to the HFC network infrastructure. Well, perhaps that’s the wrong question to ask. He is a highly respected published speaker, both domestically and internationally. Its main advantage lies in its range and data transmission rate. The ARRIS SB8200 and the ARRIS CM8200 are two of the very powerful DOCSIS 3.1-based modems that have been conquering the internet networking market. This often translates directly into more satisfied customers. One of the main changes to DOCSIS 3.1 is orthogonal frequency domain multiplexing (OFDM).
