Reflective semiconductor optical amplifierRSOA, and RSOA module and passive optical network using RSOA

摘要

The present invention provides a PON capable of improving the utilization of economic efficiency and bandwidth using the RSOA, the RSOA mounted doedoe polarization dependent property is enhanced RSOA, and RSOA module capable to compensate the optical loss caused by the optical link. The PON includes a central base station (Central Office: CO) comprising a first receiver (receiver) for the light source (optic source) and receives uplink signal for the downlink signal transmission; Downstream signals for reception by the second receiver and the downstream signal to receive an uplink signal to the re-modulated by transmission loop-back (loop-back) method of the reflective semiconductor optical amplifier (Reflective Semiconductor Optical Amplifier: RSOA) each including at least one subscribers only (Optical Network Terminal: ONT); And a central base station and subscriber outdoor node for relaying between the end (Remote Node: RN); jimyeo provided with, and input and output of the uplink signal and the downlink signal between the outdoor node and each subscriber end is made through one of the optical fibers, outside node that includes an optical power splitter (splitter) for each port directed to the customer premises.
