Moca cable too long7/28/2023 ![]() The maximum cable distance supported between the root and the last outlet is 300 feet, with a maximum attenuation of 25 dB.įIGURE 1: MoCA Physical and Logical Topologies MoCA provides an IP network over a coaxial in-home plant, and it operates over the hierarchical (branching tree) physical topology of the existing home coaxial cable plant. As a result, the service provider is compelled to support enhanced services in an unknown/uncertified environment. This infrastructure has been outside the domain of service providers and is largely installed by home builders, contractors and, in many cases, home owners. ![]() The integrity of the home’s coaxial cable plant is the wild card in the MoCA business case because of its previously unmanaged nature. To do so in a MoCA environment requires traditional and new testing measures to verify that the home network can support the new services. To win and retain customers, it is imperative that service providers get it right the first time. With this growth, support costs incurred as a result of quality and performance issues in the home will affect the profitability and success of home network deployments significantly. According to ABI Research, “In homes receiving cable television, MoCA, one of the most widely supported home media networking technologies, will be supported by some 15 million next-generation set-top boxes by 2014.” Multi-room DVR is first application being deployed but, as consumer demand grows, such services as high-speed data and voice also will be delivered over this next generation “whole home”-enabling technology. The Multimedia Over Coax Alliance (MoCA) provides a standard that satisfies the need for this new IP-enabled coaxial network in the home. This growth and demand for new video services, including digital video recorder (DVR) sharing (also referred to as “multi-room DVR sharing”), require an IP-enabled in-home network with guaranteed throughput to deliver a positive customer experience. Other targeted in-home, video-based applications include video on demand (VoD) multi-player gaming music, photo and home video sharing home security and automation and smart grid. Analyst firm The Diffusion Group (TDG) anticipates that, by 2020, there will be 3.6 billion non-portable, network-enabled video nodes in homes worldwide, and more than 5 billion by 2030. In the next decade, consumer electronics with embedded Internet and IP video support will be widely available. Market growth and competition for enhanced video services revenue have MSOs and telcos scrambling for technology and operational advantages.
