Problems solved by technology
Since the high-speed optical receiving device part is packaged in a BOX type package, bare fiber ferrule coupling is required, the coupling is difficult, and the flexible circuit board needs to be welded to connect with the main board. The process is complicated, the cost is high, and the performance is unstable.

The invention provides a small hot plug high-speed light receiving module. The module comprises a base, an upper cover, a high rate X-ray receiving unit, a PCB and an unlocking device, wherein the base comprises a light input port, an unlocking work station and an unlocking reset column; the high rate X-ray receiving unit comprises 1*N paths of light signal AWG chips, a PD array chip and a TIA chip, wherein the 1*N paths of light signal AWG chips demultiplex a high rate X-ray signal of an input end into N paths of light signal and output the N paths of light signal, the rates M of all paths oflight signal are equal, the PD array chip and the TIA chip are used for performing photoelectric conversion on the light signal and then amplifying and outputting the electric signal, the PD array chip and the TIA chip are in COB package separately with the PCB and are output outward through an edge connector of the PCB; the unlocking device comprises a straight pulling pull ring, a pair of slideblocks with an unlocking terminal fixedly connected with the pull ring, and a torsion spring, lock catch holes for fixing two terminals of the torsion spring are arranged between the two slide blocks, when in installation, two ends of the torsion spring surround the unlocking reset column, so as to fix two ends in the two lock catch holes respectively.
Description
technical field [0001] The invention relates to a high-speed optical communication WDM LAN optical receiving module, in particular to a miniaturized hot-swappable high-speed optical receiving module. Background technique [0002] WDM LAN ROSA wavelength division multiplexing high-speed optical receivers are widely used in high-performance computing system interconnection, data center Internet system, server and storage area network interconnection, core network router and transmission interface and other fields. At present, the WDM LAN R optical receiving module usually adopts a WDM LAN optical receiving device packaged in an airtight package in the module shell. The device is electrically connected to the module PCB through its flexible circuit board, and then through the gold finger of the PCB. , and connect with network equipment to realize hot-swap function. Since the high-speed optical receiving device is packaged in a BOX type package, bare fiber ferrule coupling is r...
