Laser Diodes & Sources
The 3400 series 14xxnm, 300mW laser diode is wavelength selected between 1420nm and 1510nm using grating-stabilized, polarization maintaining(PM) fiber. It is fabricated in a hermetically sealed 14-pin butterfly package. The laser diodes contain thermoelectric cooler (TEC), thermistor, monitor photodiode, optical isolator to secure high quality laser performance. The Pump Laser is ideal for distributed or discrete Raman amplification applications (1420nm to 1510nm). Up to 300mW power and high thermal efficiency enable longer links and spans, lower bit error rate(BER), and greater wavelength coverage for 40GHz and ultra-long haul(ULH) systems

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
1485nm FBG Pump Laser Diode: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1480nm, 1485nm, 1495nm 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: 0.9mm Tube, Bare. 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: 1480nm, 1485nm, 1495nm. 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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
