MoCA, Broadband Forum team to offer fibre extension over copper

News and Business

MoCA®, (Multimedia over Coax Alliance) and the Broadband Forum, have partnered to offer PON fibre network providers and service operators a low-cost fibre access extension standard using existing coaxial cabling and Fibre to the Extension Point (FTTep) architecture. The technology has been pioneered largely by Sweden-based InCoax, which has seen its In:xtnd product gain traction in a number of countries in Europe, and most recently in North America, with its latest trial on the continent worth SEK1.5 million.

MoCA Access 2.5 delivers 2.5 gigabits per second on the media access control (MAC) layer over existing coaxial cabling in Single Family Units (SFUs), Multi-Dwelling Units (MDUs) and commercial buildings. The spectrum for MoCA Access 2.5 is selectable between 400 MHz to 1675 MHz which allows the technology to coexist with other services including Cable-TV, DOCSIS, direct broadcast satellite, or terrestrial TV services. MoCA Access 2.5 is deployed as a Point-to-Point (P2P) or Point-to-MultiPoint (P2MP) topology from FTTep locations based on the building’s existing coaxial network infrastructure.

In its market report Utilizing Existing Copper Infrastructure for Deployment of Fiber-grade Services, the Broadband Forum outlines a number of scenarios for FTTep deployment, one of which is shown below.

In the indoor FTTep deployments, a distinction is made between three options:

  • FTTepIB typically located in the basement of the SFU or MDU building with phoneline or coax infrastructure available.
  • FTTepIF typically located on a floor level in the MDU building with phoneline or coax infrastructure available.
  • FTTepIL typically located in a loft of the MDU building with only coax infrastructure available.

The cost-effective and rapidly deployable MoCA Access™ 2.5 provides operators the ability to use FTTep architecture for multi-gigabit network bandwidth over existing coaxial cable building infrastructure without ducting challenges or other restrictions that might prevent seamless fibre deployments.

“MoCA and Broadband Forum standards solve industry challenges and provide ultra-high bandwidth for customers to work, learn, and stream,” said Dr. Leonard Dauphinee, president of MoCA and vice president and CTO of Broadband Products at MaxLinear. “Collaboration across both organisations by MoCA member InCoax ensured TR-419 includes the inherent advantages of MoCA Access™ 2.5.”
