ABSTRACT:
Provided are high power PLC optical Tx module and PLC optical Tx/Rx module. The PLC optical Tx/Rx module is located in an OLT of a PON system. The high power PLC optical Tx/Rx module includes a photodiode, a laser diode, an SOA, an optical coupler, and a PLC platform. The photodiode converts an input optical signal into an electrical signal, and the laser diode generates an optical signal of a predetermined wavelength. The SOA amplifies the optical signal generated by the laser diode, and the optical coupler couples optical signals, outputs the coupled signal to a splitter, divides an optical signal from the slitter, and outputs the divided signals to the photodiode. The PLC platform incorporates the photodiode, the laser diode, the SOA, and the optical coupler into one package to allow an optical signal to be output with high power.
