ARRIS Shows 4.5 Gbps Downstream DOCSIS

At this week’s NCTA Cable Show in Chicago, ARRIS will demonstrate DOCSIS downstream file transfer throughput of 4.5 Gbps. This is achieved by transmitting over 128 DOCSIS downstream channels into a single Fiber Node. In the demo, an ARRIS 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 Bandwidth Monitor will illustrate that the total downstream bandwidth sent into the Fiber Node remains fairly constant at about 4.5 Gbps.

ARRIS is also demonstrating a proof-of-concept implementation of a 5-200 MHz high-split DOCSIS upstream system with 575 Mbps of DOCSIS upstream bandwidth being transmitted over 24 DOCSIS Upstream channels out of a single Fiber Node. This demo uses a single ARRIS 24U CAM to receive the high-split 5-200 MHz upstream spectrum from a Fiber Node. This record-breaking upstream bandwidth is intended to help the industry explore the future frequency allocations of HFC to protect its value and viability for many years to come.
