AI Technical Summary

Technical Problem

In existing enterprise network optical transmission systems, 1-to-16 channel multiplexing and demultiplexing devices suffer from problems such as large size, high insertion loss, difficult assembly, and substandard performance. They cannot meet the low loss and high stability requirements of high-speed optical communication systems, and the yield rate is low, making it difficult to achieve large-scale mass production.

Method used

By employing a multi-channel multiplexing and demultiplexing optical assembly, the first, second, and third optical components work together to utilize space in three directions, reducing the number of optical path reflections and transmission paths, improving space utilization, reducing insertion loss, mitigating problems caused by processing errors and assembly positioning errors, and enhancing the isolation between channels and the uniformity of insertion loss.

Benefits of technology

It effectively reduces the overall size of the multiplexing/demultiplexing device, lowers insertion loss, improves optical performance, reduces assembly difficulty, increases yield, facilitates mass production, and is suitable for large-scale deployment of 1-to-16 channel multiplexing/demultiplexing devices in enterprise networks.

Abstract

This invention provides a multi-channel multiplexing / demultiplexing optical component, a multi-channel multiplexing / demultiplexing method, and optical devices, including a first optical component, a second optical component, and a third optical component arranged sequentially along a first direction. The first optical component realizes beam switching between a total mixed beam and multiple first-demultiplexed mixed beams. The second optical component is optically coupled to the first optical component to realize beam switching between an optical mixing group and multiple first-demultiplexed mixed beams. The optical mixing group includes multiple mixing subgroups, each including multiple second-demultiplexed mixed beams. The third optical component is optically coupled to the second optical component to realize beam switching between the optical mixing group and multiple target beams. The third optical component has a first port, a second port, and a third port. The first and second ports are both located at one end of the third optical component closer to the second optical component, and the third port is located at the other end. The first port is used to transmit the optical mixing group, and the second and third ports are used to transmit the target beams. This invention has small size, low insertion loss, and good optical performance.
