Fibercore’s IsoGain™ range of Erbium Doped Fibers (EDFs) offer a wide selection of absorption and cut-off wavelengths to allow the best choice of fiber for each type of Erbium Doped Fiber Amplifier (EDFA) design.
Fibercore’s low absorption fibers offer best-in-class efficiency for C-band amplifiers whilst higher absorption fibers are optimized for L-band EDFAs.
High cut-off wavelength (HC) fibers have larger core diameters, reducing non-linear effects and increasing efficiency at higher pump powers.
The core composition of Fibercore’s IsoGain™ has been engineered to generate a substantially flattened wavelength response that closely matches that of other leading fiber types.

 

Advantages:
• High efficiency core composition
• ‘HC’ variants optimized for high pump power EDFAs
• High absorption fibers for L-band amplifiers and mini/micro C-band EDFAs
• Wide range of absorption values for EDFA design optimization

 

Typical applications:
• EDFAs / Telecoms
• ASE Light Sources
    o Gyros
    o Current Sensors
    o Distributed Sensor Systems
• Fiber Lasers
• Biomedical Illumination
• Optical Coherence Tomography (OCT)
