Coolerless DWDM Laser Diodes (CDLD) Series

Product Description: Coolerless DWDM laser diodes are passive wavelength locked external cavity lasers without mode hopping at ITU DWDM wavelength grids, intended for application in analog AM, forward path CATV and other DWDM applications. These laser diodes have high output power, excellent wavelength stability and low noise performance. The lasers are packaged in standard TO56 package with a high optical coupling efficiency and inclusion of an isolator, a monitor PD and a thermistor. We have options of output fibers of SM, PM and other fibers. The products are Telcordia GR-468 qualified, and in compliance with RoHS requirement.

Applications:

  • DWDM fiberoptic networks
  • DWDM transceivers
  • Fiberoptic sensors 
  • High performance laser sources 
  • CATV transmitters

Features:

  • Stable DWDM ITU wavelength grids
  • High power output
  • Direct 2.5G modulation laser
  • TO56 package
  • Built-in thermistor and optic isolator
  • High reliability
