Cable Show 2011: Arris To Stage Monster DOCSIS Demo

Aiming to show the massive capacity available in today's hybrid-fiber coax networks, Arris will show its C4 cable modem termination system delivering real file-transfer throughput of 4.5 Gigabits per second of DOCSIS 3.0 downstream traffic as well as 575 Mbps upstream.

The applications aren't practical for MSOs to deploy currently, because cable operators do not have enough free spectrum to launch services with such high speeds.

But according to Arris the proof-of-concept demos -- which it claims are industry record-breaking bandwidth levels over DOCSIS -- are designed to illustrate that its C4 platform is capable of handling very high-scale bandwidth that cable operators may need in the future for IPTV delivery.

In the downstream demo, Arris will show real file transfer throughput of 4.5 Gbps of DOCSIS downstream traffic being transmitted over 128 DOCSIS downstream channels into a single fiber node. The C4 CMTS will be configured using four newly released 32 Downstream Cable Access Modules (32D CAMs) to source the 128 DOCSIS downstream channels into the fiber node.

The demo also will show a proof-of-concept implementation of a 5-200 MHz "high-split" DOCSIS upstream system with 575 Megabits per second of DOCSIS upstream bandwidth being transmitted over 24 DOCSIS Upstream channels out of a single fiber node. That uses a single 24U CAM, which Arris announced last week.
