The differences between theory and practical implementations can be significant, so stay aware of these scenarios. ... Make sure to choose a DOCSIS 3.0 or 3.1 … DOCSIS 3.1 Modem Router Combo vs. DOCSIS 3.1 Modem. This article belongs to a monographic series about the evolution of telecommunication technologies, FTTH and Cable (DOCSIS… Facebook; Twitter; Facebook; Twitter; Solutions. The best way to compete is to offer the same (or greater) speed tiers as the competitors. and … He has over 25 years of broadband cable and telecommunications industry experience specializing in RF, DOCSIS, PNM, and Internet Protocol. [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. However, gigabit service over a fiber … DOCSIS 3.1 enables state-of-the-art speeds to be delivered over HFC networks; it has flexible modulation, excellent error correction and doubles the spectrum as it allows a wider frequency. Fiber may be faster, but … FAQ, DOCSIS 3.1 Cable Technology vs FTTH – Fiber To The Home. The upgrade to DOCSIS 3.1 will give them the fastest residential service nowadays at a significant cost, and replacing the HFC network with fiber will provide a future-proof infrastructure but … Reliability is a challenge for DOCSIS due to the mechanical and environmental degradation and failures that occur in the coaxial plant. 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. As you can see by now, there is not a right or wrong for this kind of technology. Your email address will not be published. Normally, it is used by many cable television operators in order to provide Internet access over their existing hybrid fiber-coaxial infrastructure. OFDM makes quantum leaps in the amount of data capacity and speed available – … Because of this, FTTH – Fiber To The Home is already considered one of the best technologies to handle consumer network demands in the coming decades. However, there's also a new standard, known as DOCSIS 3.1, which maxes out at a whopping 10Gbps. The reason for wanting Ethernet is the efficiency of low-level protocols. 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). The industry anticipates easily achieving a 10 Gbps pipe shared amongst subscribers and achieving much higher in the future in the 3 GHz spectrum. Be it aerial or buried, there is a lot involved with permits, trenching, not to mention the headaches of tearing up people’s lawns. Fiber is the best choice for most customers, as it provides high-bandwidth connections up to 1,000 Mbps download and upload speed. It is very tough to win a marketing war against raw speed. Should I go for FTTH or DOCSIS? 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? DOCSIS 3.1 suite of specifications now support capacities of up to 10 Gbit/s downstream and 2 Gbit/s upstream. The benefit with coax is that it is already there, passing more than 90% of the homes in the U.S. But you will not go wrong if you choose another option…. That is 10 times more capacity than DOCSIS 4.0 and it exists today. Remote portions of a WAN can use TCP/IP over DOCSIS, but it imposes a high level of overhead. 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. In this TCO analysis, we showed >50% reduction in TCO for an outdoor use case of backhauling small cells when served by DOCSIS … 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. If you look at fiber objectively from any other perspective it outperforms DOCSIS. Both cable operators and telecom operators can deploy fiber and are doing so today. There are pros and cons to both options. The original question was can DOCSIS 3.1 or even future versions of DOCSIS compete with fiber? 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. This would give us: That exceeds our 10G initiatives. Compare products and prices in one single place. 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. 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!). Should we therefore abandon DOCSIS? Physics: Fiber wins 2. 100 Gbps is generally implemented as 10×10 Gbps on 10 “channels” or different wavelengths of light. — However, with just plain facts fiber wins in reliability. 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. Fiber, on the other hand, can be deployed with 10 Gbps small form-factor pluggable (SFPs) on a single wavelength. 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. Fiber allows for significantly faster transmission speeds, so has transformed data, video and voice services. The creation of DOCSIS 3.1 has made this choice more difficult because DOCSIS … 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 … 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. Well, perhaps that’s the wrong question to ask. The cost to install new fiber is on parity with coax. Pingback: DOCSIS 4.0 | Providing 10 Gbps pipe at the right cost. In some cases, DOCSIS over a glass architecture is, for sure, a perfect option for delivering broadband services to homes over fiber.  Mr. Volpe holds a MSEE and a BSEE. Absolutely not. Or is the other way around? 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. My point is that it’s important that we understand what we are up against and not put blinders on. Absolutely not. Safe shopping – Twoosk is a certified platform by “Trust Ecommerce Europe” that guarantees a safe shopping experience by using the most well-known payment methods and that partners with the most reliable logistic companies to ensure that delivery times are met. 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. The difference between cable and fiber is that cable is sent over copper TV lines, while fiber … 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 … If competition is not the case, the option to deploy lower-cost EPON technology in new areas might be a choice…, The fact is that to choose the right path to follow might involve a few challenges: whereas DOCSIS 3.1 enables state-of-the-art speeds to be delivered over HFC networks, RFoG enables FTTH with HFC back office and HFC consumer premises equipment, for example. cost per capacity) is lower for GPON than it is for DOCSIS 3.x. market. Through a SW upgrade, some CMTSs can offer partial DOCSIS 3.1 support, still better than DOCSIS 3.0. One has to choose according to the demands of the business and what the company is dealing with. 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.. 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. You might be wondering whether it is better to go for a DOCSIS 3.1 modem router combo or just stick with a DOCSIS 3.1 modem. 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. The best DOCSIS 3.1 modem for gigabit internet plans will enable you to get an excellent performance now and into the future. 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. 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. DOCSIS 3.0's highest possible speed is 1Gbps, also known as “Gigabit internet." 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?
