Detailed information

SOI high-speed optical switch 1X8

 

Silicon photonic chips are used for high-speed optical switches. Their principle is similar to demux, which divides a single path of light into multiple paths, and only selects one path at a time.

The current design comprehensively considers the maturity of the process, integration difficulty, and flexibility. In Sample A1, it is decided to adopt a pure optical fiber modular solution, and one module is in the form of 1x8. The input and output of the optical switch use optical fiber/optical fiber array. Purchase modular products, that is, already packaged modules with optical fibers. The module can be directly used by welding on the PCB.
