METHOD AND APPARATUS FOR CONTROLLING COMMUNICATIONS IN A PASSIVE OPTICAL NETWORK

摘要

A method and system provide a unique communication and protocol between an optical line termination device and a plurality of optical network units sitting at different distances from the optical line termination device. The OLT determines the distances between it and each ONU (302) and then requests communications from the ONUs in ascending order from the nearest to farthest (306, 308). The OLT also determines a time delayed period between the neares t ONU and the farthest ONU and awaits that time delay period (312) before initiating subsequent ONU communication with the ONUs.
