Laser Transceiver Integrated Module

This product specification sheet describes the performance indicators of the laser transceiver integrated module. Laser transceiver integrated module, mainly used in laser communication systems. There are only two types of modules for users, distinguished by laser working wavelength. Among them, the center wavelength of optical transceiver module A is ITU-C46 channel, and the center wavelength of module B is ITU-C18 channel. Other parameters have the same performance requirements.

Application Scenarios:

Drone laser communication, satellite laser communication
