Title:
METHOD AND SYSTEM FOR PROVIDING DOCSIS SERVICE OVER A PASSIVE OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO2005076911
Kind Code:
A3
Abstract:
A Passive optical network (PON, 8, fig. 1) used to transport traffic signals between a headend (4, fig. 1) and subscriber equipment increases performance and reduces costs while potentially allowing the retention of legacy equipment at the headend and at the subscriber's cable modem. Upstream and downstream traffic signals are converted to upstream and downstream optical wavelengths at customer equipment and headend equipment, respectively, and transported across the PON. The optical signals are converted to electrical signals at the other respective ends, or edges, of the PON, and DOCSIS operation and processing occurs as known in the art. Upstream traffic can be carried at unconventional upstream frequencies. The upper frequency limit of traffic signals is higher than for an HFC thus providing for potentially more channels, either upstream or downstream.
