| titleOfInvention | 400G COB optical module for optical chip flip-chip of high-speed long-distance transmission |
| abstract | The invention relates to a 400G COB optical module for inversely installing an optical chip for high-speed long-distance transmission, which comprises a laser chip, a detector chip, a DSP chip, a PCB and an optical module heat sink, wherein the PCB and the optical module heat sink are arranged in parallel, the top surface of the DSP chip is attached to the optical module heat sink, the bottom surface of the DSP chip is welded on the PCB, the heat dissipation surface of the laser chip and the heat dissipation surface of the detector chip are respectively attached to the optical module heat sink, a plurality of gold balls are fixedly arranged on the PCB, the pins of the laser chip and the pins of the detector chip are respectively welded with the plurality of gold balls in a one-to-one correspondence manner, and the gold balls are in communication connection with the DSP chip through the PCB. The COB optical module has the advantages that the laser chip and the detector chip are good in heat dissipation performance, signal integrity and reliability, the product yield is improved, and the product production cost is reduced. |
