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)
