OPTICAL TRANSCEIVER AND METHOD TO ASSEMBLE THE SAME

摘要

A coherent optical transceiver is disclosed. The coherent optical transceiver installs an integrated coherent receiver (ICR), an optical modulator; an intelligent wavelength tunable laser diode (i-TLD), a digital signal processor (DSP), a driver to drive the optical modulator, and so on within a compact housing. The ICR is connected to the printed circuit board (PCB) through flexible printed circuit (FPC) boards and mounted thereon through a holder. The holder forms a gap against the PCB, where the FPC boards pass through the gap and connected on the pads formed on the surface of the PCB beneath the holder.

主权项

1. An optical transceiver comprising:
an optical module to receive an optical signal, the optical module having a first lead pin in a side thereof; and a printed circuit board (PCB) to mount an electronic circuit communicating with the optical module through a first flexible printed circuit (FPC) board, the PCB mounting the optical module thereon through a holder, the holder forming a gap against the PCB; and wherein the first FPC board is fixed to a first pad on the PCB by soldering, extracted outwardly from the first pad, passes through the gap between the holder and the PCB, and connected to the first lead pin of the optical module.
