Product description

A fiber Bragg grating (FBG) precisely locks the center wavelength over extended power and temperature ranges.

The modules are packaged using unique laser-weld packaging technology for high reliability over harsh operating conditions and are available with a fiber Bragg rating, thermoelectric cooler, thermistor, monitor photodiode, and UniDry™ getter. G&H’s pump lasers are designed to meet the requirements outlined in Telcordia GR-468-CORE.

Key features

  • Internal cooler and thermistor
  • Fiber Bragg Grating (FBG)
  • Telcordia GR-468-CORE compliant
