The new Coax Link Controller can deliver up to 1.4 Gbps over a building's coaxial network and is a cost-effective and competitive solution that allows operators to guarantee network capacity and quality of service for all users. Depending on the modem type, individual subscribers can achieve broadband speeds of up to 350 Mbps to meet the growing demand for OTT video streaming services and connected TV. Today, subscribers require high-bandwidth fiber optic connections to their homes, supporting symmetrical services for content delivery and interactive gaming.
Helge Tiainen, Product Marketing Manager at InCoax Networks, comments: “Bringing fiber optic connections to homes would solve the bandwidth problem, but it is too expensive to be economically viable in older apartment buildings across Europe. With the next-generation InCoax Coax Link Controller, operators can deliver high-speed connections to customers by utilizing existing coaxial cabling within apartment buildings – at a significantly lower cost compared to using fiber optics all the way to the end of the line, and with the ability to guarantee sufficient connection speed for all subscribers.” The
InCoax Coax Link Controller is a network access node that enables the delivery of signals from fiber networks to individual subscribers via existing coaxial cabling. As the only European manufacturer of this technology, InCoax uses Entropic’s c.LINK Ethernet over Coax MoCA chipset solution, which allows the Coax Link Controller to support broadband speeds of up to 1.4 Gbps with 8 RF channels for download and upload. Depending on the modem design, two RF channels can be combined, and individual subscribers can achieve a maximum speed of 350 Mbps. The Coax Link Controller is designed with a network processor capable of handling up to 10 Gbps, allowing multiple Coax Link Controllers to be connected to the incoming fiber optic cable of an apartment building.
Cable TV uses a spectrum up to 862 MHz. InCoax's IP over Coaxial technology utilizes the unlicensed spectrum above this, from 950 MHz to 1525 MHz. Data services can thus coexist with existing television content. The higher spectrum is generally not an issue, as most coaxial cabling in buildings can handle it. Older networks have been upgraded during the transition from analog to digital television. Coaxial cables can carry signals up to 2400 MHz with acceptable attenuation within the cable lengths inside buildings. In many cases, however, splitters and taps need to be replaced to support up to 2400 MHz, at a lower cost.
With the latest MoCA 1.1 access technology, up to 175 Mbps of capacity per RF channel can be provided. This gives each subscriber 100 Mbps of browsing capacity and up to three HD IPTV channels. On average, there are 2.7 TVs per apartment in Europe. Coaxial cables are very robust against external interference due to their shielding. Unlike telephone lines, these cables are always available in the building, whether in the basement or the attic.
