RECEIVER OPTICAL ASSEMBLY AND ASSEMBLY METHOD THEREOF
First Claim
1. A receiver optical assembly, comprising:
- an optical platform, a receiver optical port and a wavelength division multiplexer being arranged along an optical path on the optical platform;
a circuit board, a photodetector array being disposed on the circuit board; and
a mounting block, a focusing lens and an optical path shifter being disposed on the mounting block, the mounting block being fixed on the circuit board, and the optical path shifter being placed above the photodetector array,wherein incident light containing a multi-channel optical signal enters through the receiver optical port, the wavelength division multiplexer divides the incident light into a plurality of single-channel optical signal beams, and the single-channel optical signal beams are coupled to photodetectors on the photodetector array after passing through the focusing lens and the optical path shifter on the mounting block.

Abstract
A receiver optical assembly includes: an optical platform, a receiver optical port and a wavelength division multiplexer being arranged along an optical path on the optical platform; a circuit board, a photodetector array being disposed on the circuit board; a mounting block, a focusing lens and an optical path shifter being disposed on t the mounting block, the mounting block being fixed on the circuit board, and the optical path shifter being placed above the photodetector array. Incident light containing a multi-channel optical signal enters through the receiver optical port, and the wavelength division multiplexer divides the incident light into a plurality of single-channel optical signal beams. The single-channel optical signal beams are coupled to photodetectors on the photodetector array after passing through the focusing lens and the optical path shifter on the mounting block.
