Laser Diodes & Sources
The NDFB serial fiber coupled laser features narrow spectral linewidth, low noise, and cost-effectiveness. It is based on semiconductor on chip technologies. They have maximum output power of about 20mW and a built-in power monitor for precision power control as well as TEC cooling for wavelength stability. They are available at 1550nm. A heat sink is required to remove the heat preventing damage. We offer driving electronics to precisely control both the output power and temperature (wavelength)

Wavelength: 1550nm · Output Power: 10mW · Linewidth: 100kHz · Driver: No · PD: Yes · Fiber Type: SM28 · Fiber Buffer: 900µm Tube · Fiber Length: 1.0 m · Connector: None
Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Narrow Line Fiber Coupled Lasers: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, PM1550) must match the connected components.

Technical FAQ
Fiber Type: SM28, PM1550 · Fiber Buffer: 900µm 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: 1550nm. 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.
Driver: No, Yes. Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
