Abstract

The invention is suitable for the optical communication field and discloses a multi-wavelength multiplexing / demultiplexing parallel light receiving / emitting component. Four laser emitting chips or detector receiving chips arranged on a PCB circuit board are located on the same straight line; four collimating lenses are respectively located above the four laser emitting chips or detector receiving chips, and top light spots are aligned to the centers of photosensitive surfaces of the four detector receiving chips or the four laser emitting chips; four wavelength division multiplexing / demultiplexing optical filters are respectively arranged above the four collimating lenses and parallel to each other, the reflecting surfaces face to the downside, and the angle between each reflecting surface and the PCB circuit board is 45 degrees; a fifth collimating lens is located at one side of the reflecting surface of each wavelength division multiplexing / demultiplexing optical filter, and the optical paths between the fifth collimating lenses and the wavelength division multiplexing / demultiplexing optical filters are vertical to the optical paths between the wavelength division multiplexing / demultiplexing optical filters and laser emitting chips or detector receiving chips. Several channels only need one optical fiber to perform communication transmission, and the optical fiber cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of optical communication, in particular to a multi-wavelength multiplexing / demultiplexing parallel optical transceiver component. Background technique [0002] With the comprehensive popularization of the information industry, the explosive growth of the global data volume, the construction of global data centers is in full swing. Parallel optical modules are favored by the industry due to their large communication capacity and low energy consumption, and have developed rapidly in recent years. The parallel optical module refers to the realization of one-to-one transmission of multi-channel lasers and multi-channel detectors through multiple optical fibers in one module. The low power consumption brought about by device integration and miniaturization makes the parallel optical module generate and dissipate much less heat than multiple discrete devices. Parallel optical modules mainly rely on high-density integratio...
