Technical content

These lasers are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. Devices are available with kink free output powers to 750mW. The LC96 ‘U’ series pump module utilises a double Fiber Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes. Features:

  • Double Fiber Bragg Grating wavelength stabilization
  • Ultra High output power, up to 750mW kink free
  • Polarization maintaining fiber pigtail
  • Internal thermoelectric heatpump and monitor photodiode
  • Hermetically sealed 14 pin butterfly package
  • Telcordia GR-468-CORE compliant
  • Field proven high reliability
  • RoHS compliant Applications:
  • Low noise erbium doped fiber amplifiers (EDFAs)
  • Dense wavelength division multiplexing (DWDM) EDFAs
  • CATV Applications ULTRA High Power 980nm Pump Laser Module - Grating Stabilized, 750mW LC96U*
