SYSTEM AND METHOD FOR TRAFFIC DISTRIBUTION IN AN OPTICAL NETWORK

摘要

In accordance with the teachings of the present invention, a system and method for traffic distribution in an optical network is provided. In a particular embodiment; a traffic distribution module in a passive optical network (PON), includes a filter configured to receive downstream traffic in a first set of one or more wavelengths and a second set of one or more wavelengths from an optical line terminal (OLT), direct the traffic in the first set of wavelengths to a primary power splitter, and direct the traffic in the second set of wavelengths to a first connector. The traffic distribution module also includes a primary power splitter and a plurality of secondary power splitters. The primary power splitter is configured to receive the traffic in the first set of wavelengths and distribute the traffic in the first set to the plurality of secondary power splitters coupled to the primary power splitter such that optical network units (ONUs) in the PON receive the traffic in the first set of wavelengths. The traffic distribution module also includes a first connector configured to couple to a first module connector of a pluggable module and to forward the traffic in the second set of wavelengths to the pluggable module via the first module connector. The traffic distribution module also includes a plurality of second connectors configured to couple to a plurality of second module connectors of the pluggable module, receive the traffic in the second set of wavelengths from the pluggable module via the associated second module connectors, and forward the traffic in the second set to the plurality of secondary power splitters for distribution to particular ONUs in the PON.
