1625nm Pulse Laser Modules for OTDR

Our 1625nm pulse laser modules for OTDR are equipped with a high power FP chip with low threshold current and high-efficiency output. Capable of working with a high current, the pulsed laser module can operate in dual mode, pulse and direct current. The multi-mode fiber is optional. This laser diode is generally used in the communication and testing systems that use OTDR and Raman light reflection principles.
