BOSA (Bi-Di Optical Subassembly) optical structure used for high-speed receiving and transmitting system

Abstract

A BOSA (Bi-Di Optical Subassembly) optical structure used for a high-speed receiving and transmitting system comprises a shell; the shell is internally provided with a transmitting-end TOSA optical structure and a receiving-end ROSA optical structure; the transmitting-end TOSA optical structure comprises a wavelength division multiplexing device (MUX), an isolator and a receiving collimator; and the receiving-end ROSA optical structure comprises a wavelength division demultiplexing device (DEMUX) and a second collimator. The BOSA (Bi-Di Optical Subassembly) optical structure used for the high-speed receiving and transmitting system is characterized in that the shell is internally provided with a baffle; the baffle separates the transmitting-end TOSA optical structure and the receiving-end ROSA optical structure; the transmitting-end TOSA optical structure also comprises a first rhombic prism bending a beam emergent from the isolator to the receiving collimator; and the receiving-end ROSA optical structure also comprises a second rhombic prism bending a beam emergent from the second collimator to the wavelength division demultiplexing device. by adopting the micro optical structure design, beam insert loss can be greatly reduced, the coupling efficiency is improved, power consumption is reduced, and long-distance transmission of optical signals is facilitated.

Description

technical field [0001] The invention relates to an optical transceiver module in optical fiber communication technology, in particular to a BOSA optical structure used in a high-speed transceiver system. Background technique [0002] With the increasing development of the communication field, traditional transmission technologies have been difficult to meet the requirements of transmission capacity and speed. In typical application fields such as data centers, network connections, search engines, high-performance computing, etc. Carriers and service providers have deployed a new generation of high-speed network protocols, which require corresponding high-speed transceiver modules to meet high-density and high-speed data transmission requirements. In the high-speed information transceiver system, it is necessary to replace the traditional optical module with a high-density optical module. Using multi-channel optical transceiver technology, more transponders and receivers...
