Laser Diodes & Sources
We provide cost-effective fiber-coupled laser sources with a wide range emitting spectrum from 370nm to 2000nm and line width from 10kHz to broadband to select. Each benchtop laser source features a pigtailed laser and high-precision, low-noise auto-feedback drive electronics to ensure constant output power or a constant driving current, and an integrated temperature control unit maintains optimal operating conditions. Each unit features a front fiber output connector and a universal power supply compatible with 100 to 240 VAC. We offer two packages: benchtop for ease of use and compact module for system integration. The user interface benchtop includes an intuitive LCD display for independent control of output power and temperature via two front rotating knobs. The module has two front output power and temperature settings.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
1550nm Fiber Coupled DFB ITU Laser Source - 1-70mW: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, PM1550) must match the connected components.
1550nm Fiber Coupled DFB ITU Laser Source - 1-70mW: Fiber-optic instrumentation depends on preserving the optical budget through the complete path. The 1550nm, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, PM1550) must match the connected components.

Technical FAQ
Fiber Type: SM28, PM1550 · Connector: Non, FC/APC, FC/PC, Special. 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, Special. 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.
Control Mode: Constant Current, Constant Power. 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.
