1625nm Pulse Laser For OTDR
The FPLD series fiber-coupled laser diodes are designed with a GaAs quantum well structure. These diodes feature a built-in photodiode for precise monitoring and feedback control of the laser’s output power. Housed in standard TO packages, these diodes are pigtailed to a 1-meter long single-mode fiber terminated with an FC/APC connector. Each unit undergoes rigorous testing prior to shipment to ensure reliability. The laser cavity is highly sensitive to light reflection. We have an isolator to block reflections, consequently providing emission stability. Additionally, we offer a cost-effective, high-performance feedback laser diode controller/driver kit that maintains a constant and adjustable output power, along with an externally cooled co-axial laser mounting fixture to stabilize the output wavelength. It is available in a module or benchtop with an integrated isolator.

System integration
Integration and compatibility
Use these checks to connect 1625nm Pulse Laser For OTDR to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM28, PM1550, PM1310 · Fiber Buffer: 0.9mm Tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1625nm
- Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
