Cable Internet demonstrated at 4.5 Gbps

ARRIS demonstrated real file transfer throughput of 4.5 Gbps of DOCSIS downstream traffic being transmitted over 128 DOCSIS downstream channels into a single Fiber Node. An ARRIS C4 CMTS was 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. These record-breaking bandwidth levels may be required for large-scale IP Video systems in the future.

The demo will also show 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.

The fastest cable internet services are 160 Mbps in Japan and 101 Mbps in New York. There is a pilot of 200 Mbps for 100 people in England.

The demo shows that if cable television channels were compressed or converted to IPTV that there would be room for true ultrabroadband communication speeds.



Other ways to get faster internet would be to increase competition for the telephone and cable companies and hope that Google decides to roll out a national ad supported Gbps internet service.
