Dual Clad Erbium/Ytterbium Doped Fiber

PM and non-PM erbium ytterbium co-doped dual clad fiber

  • Optimized for efficient energy transfer
  • Can be cleaved and spliced with standard equipment

Typical Applications:

  • High power Erbium Doped Fiber Amplifiers (EDFAs)
  • Ytterbium/Erbium Doped Fiber Amplifier (YEDFA)
  • Fiber laser
  • Light Radar (LiDAR)
  • Cable Television (CATV)
