WDM Laser Optical Module

: http://laserdiodedevice.com/6-4-wdm-laser-optical-module.html

This WDM laser optical module is composed of a passive device and active device, and features a high isolation, a high linearity, and low noise levels. Transmission is a bidirectional transmission, which is widely used in OTDR, analog transmission systems and more. We will customize different product lengths and joints according to customer needs.
