AGGREGATION DEVICES, OPTICAL MODULES, AND OPTICAL NETWORK SYSTEMS

Abstract

The present invention provides an aggregation device, an optical module, and an optical network system. The aggregation device comprises: a first port, configured to receive a plurality of coupled downlink optical signals in different wavelengths; a first component, configured to separate the coupled downlink optical signals to form a plurality of different downlink optical signals, and aggregate the plurality of received uplink optical signals into one coupled uplink optical signal and output the coupled uplink optical signal to a third port; a plurality of second ports, configured to output the plurality of downlink optical signals to corresponding bidirectional access optical modules among the plurality of bidirectional access optical modules, each receiving a plurality of uplink optical signals in different wavelengths, and outputting the uplink optical signal to the first component; and a third port, configured to output the coupled uplink optical signal to a core optical module.
