Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/115129
Kind Code:
A1
Abstract:
The present invention relates to the field of optical communications. Disclosed is an optical module, comprising a multi-path optical transmitting device and a multi-path optical receiving device. A multi-path transmitter component comprises a metal member adhered to a circuit board. An upper part of the multi-path transmitter component is used for placing elements such as a multi-path laser, a PLC chip, and a lens. The laser is electrically connected to the circuit board by means of gold wire welding. The laser passes an optical light through the lens located between the PLC chip and the laser. A laser light emitted by a corresponding laser is coupled into a corresponding PLC chip port, is multiplexed, and then enters an optical fiber component, and is output to an external optical fiber by means of an optical interface. The multi-path optical receiving device directly places a photodiode and a transimpedance amplifier onto the circuit board. An external optical signal enters the optical fiber component by means of the optical interface, is split by an optical beam splitter, and then reflected into a corresponding photodiode for optical reception, which achieves the conversion from the optical signal to an electrical signal. The element used for packaging can be reduced, and the volume is reduced.
