CableLabs Details New Remote PHY Specs for DOCSIS

CableLabs posted information on several different Distributed CCAP Architectures (including Remote PHY and Remote MAC-PHY).

Last month, CableLabs publicly issued the Remote PHY family of specifications. Theses specifications are also known as MHAv2 as these are an evolution from the original Modular Headend Architecture specifications.

In a blog posting, Karthik Sundaresan, Principal Architect, CableLabs, describes how the Remote PHY technology allows for an integrated CCAP to be separated into two components: the CCAP Core and the Remote PHY Device (RPD) with interfaces between them. One of the common locations for an RPD is the optical node device that is located at the junction of the fiber and coax plants, while the CCAP Core stays at the headend. A CCAP core can control and setup data paths with multiple RPDs situated in multiple fiber nodes.

CableLabs said it will release the set of technical reports and specifications throughout this summer.
