Claim of US Patent No. 9,287,986

1. An optical transceiver module, comprising:
a self-contained optical transmitter configured to convert externally input electric signals into optical signals to transmit
the converted input signals, wherein the externally input electric signals are directly modulated into optical signals in
a plurality of sub groups to be multiplexed; and

a self-contained optical receiver configured to receive externally input optical signals, and to convert the received optical
signals into electric signals to output the converted received signals, wherein optical signals are demultiplexed in a plurality
of sub groups to be converted into electric signals,

wherein the self-contained optical transmitter includes each of:
a plurality of electric signal conditioners configured to recover the externally input;
a plurality of laser diode drivers configured to amplify the externally input electric signals recovered by each electric
signal conditioner;

a transmitter optical sub-assembly array, which is grouped into a plurality of sub groups, and is configured to directly modulate
electric signals, which are amplified by each laser diode driver in sub groups, into optical signals, and to multiplex the
modulated signals; and

an optical MUX configured to multiplex optical signals output for each transmitter optical sub-assembly.
