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.
