US 2026/0074795 A1 · COHERENT OPTICAL TRANSMISSION SYSTEM WITH MULTI-USE LASER EMITTER AND OPTICAL TRANSCEIVER THEREOF

Abstract

A coherent optical transmission system includes two optical transceivers, each including a laser emitter, an optical splitting module, an optical modulator, an optical mixer and an optical detector. The laser emitter is configured to emit an initial light. The optical splitting module is configured to divide the light emitted by the laser emitter into a reference light and a signal light. The optical modulator is configured to modulate the signal light. The optical mixer is optically coupled to the optical splitting module. The optical mixer of the first optical transceiver is configured to optically mixing the reference light of the first optical transceiver and the signal light of the second optical transceiver, and the optical mixer of the second optical transceiver is configured to optically mixing the reference light of the second optical transceiver and the signal light of the first optical transceiver.
