    • 655nm 20mW PM FP Laser Diode

    655nm FP is a single-mode laser diode module designed specifically for optical measurement and communication. The laser adopts a standard 14-pin butterfly package, with a built-in monitoring photodiode (PD) and thermoelectric cooler (TEC), and is coupled to PM Fiber. The pigtail of this module is 0.7-1.0m single-mode polarization-maintaining fiber, with an FC/APC connector interface.

    Product features：Optical output power: 30mW；FC/APC connector；14-pin butterfly package；High-efficiency coupling to single-mode fiber；Continuous wave (CW) or pulsed operation mode；Built-in monitoring photodiode (PD) and thermoelectric cooler (TEC)；Single-mode (SM) or polarization-maintaining (PM) fiber (0.9mm diameter)

    Part Number：MP-FP-655-20-14BF-PA

    Application area：Fiber optic transmission systems | Laser interferometry | Laser indication | Test light sources
