Multi-channel optical transceiver

A multi-channel optical transceiver, comprising a printed circuit board (PCB), an optical reception module embedded in the PCB and configured to convert a received optical signal into an electrical reception signal, an optical transmission module mounted on a bottom of the PCB and configured to output an electrical transmission signal by modulating the electrical transmission signal into an optical signal, a signal processing module (electrical sub-assembly (ESA)) configured to process the electrical transmission signal and the electrical reception signal, and a flexible printed circuit board (FPCB) configured to electrically connect the signal processing module and the optical transmission module,

• wherein the optical reception module comprises:
• a pre-amplifier mounted over the PCB;
• a glass interposer mount mounted over the pre-amplifier and comprising a transmission line electrode formed over the pre-amplifier and configured to electrically connect the pre-amplifier and the signal processing module;
• and
• an optical detector mounted over the glass interposer mount and configured to detect a received optical signal and to output the detected optical signal to the pre-amplifier by converting the detected optical signal into an electrical reception signal, and
• the pre-amplifier transmits the electrical reception signal received from the optical detector to the signal processing module through the transmission line electrode by amplifying the electrical reception signal.
