The equidistant range of erbium-doped fiber (EDFS) cores provides a wide selection of absorption and cutoff wavelengths to allow optimal selection of fiber for each type of erbium-doped fiber amplifier (EDFA) design.
The low absorption fiber of the fiber core provides best-in-class efficiency for C-band amplifiers, while the higher absorption fiber is optimized for L-band EDFAs.
High cut-off wavelength (HC) fibers have larger core diameters to reduce nonlinear effects and improve efficiency at higher pump powers.
The core composition of the ISGOGAIN hole of the fiber core has been designed to produce a substantially flat wavelength response that closely matches other major fiber types.
Advantage:
1. High-efficiency core composition
2. Optimization of "HC" variant of high pump power EDFA
3. High absorption fiber for L-band amplifier and MIN/micro C-band EDFA
4. Wide range of absorption values for EDFA design optimization
