OPTICAL NETWORK TERMINAL OF THE GIGABIT PASSIVE OPTICAL NETWORK AND FRAME TREATMENT METHOD OF THE ONT

摘要

A gigabit passive optical network (GPON) system for fiber to the home (FTTH) service must provide a downstream data rate of an optical band to provide IPTV service with hundreds of channels to subscribers, and must be able to provide an upstream data rate of an optical band using a currently available BM-IC chip. A currently available BM-IC chip for a GPON has 1.244Gbps and 2.488Gbps modes. Accordingly, an optical network terminal (ONT) for a GPON that is capable of providing a downstream transmission band of 10-Gbps and an upstream transmission band of 1.244Gbps or 2.488Gbps, and a method for processing an upstream frame in the terminal, are provided. The GPON ONT can provide 20Mbps, high-definition IPTV service with 500 channels and can provide both upstream data rates of 1.244Gbps and 2.488Gbps according to a user's selection without using an additional device.
