High Absorption Reduced Cladding (HARC) Erbium Doped Fibers

For mini, micro and pluggable QSFP EDFAs

  • Reduced cladding diameter for increased flexibility and improved mechanical reliability
  • Small coating diameter for a reduced coil stack size
  • High erbium doping level for shorter fiber lengths
  • Increased numerical aperture (NA) for lower bend loss

Typical Applications:

  • Mini, micro and pluggable QSFP-style EDFAs
  • Ultra small fiber lasers
  • ASE light sources
  • Fiber Optic Gyroscopes (FOGs)
