FP Pulsed Diode Laser

The FP pulsed diode laser (for OTDR system) can operate either in the pulsed mode or DC mode. It has the advantages of low threshold current, great output efficiency, and high current-carrying capacity. This series of product can be supplied with the optional multi-mode fiber-optic output. It is mainly used for the OTDR system as well as Raman backscattering based communication and test system.
