Optical communication apparatus and method of assembling the same

摘要

An optical communication apparatus comprises a laser, a laser driver chip, a photodetector, an amplifier chip, an assembling plate and at least two I/O interfaces. The laser, the laser driver chip, the photodetector and the amplifier chip are disposed on the assembling plate. The laser is connected to the laser driver chip via transmission lines and the photodetector is connected to the amplifier chip via transmission lines. A plurality of conducting vias are formed in the assembling plate, the laser driver chip and the amplifier chip are respectively connected to different I/O interfaces via electrical transmission lines passing through the conducting vias. The laser is connected to an optical fiber to transmit optical signals, and the photodetector is connected to another optical fiber to receive optical signals. A method of assembling such an optical communication apparatus is also provided.
