Erbium Doped Fiber MetroGain™
Fibercore’s MetroGain™ range is designed for high effciency ‘Metro-style’ Erbium Doped Fiber Amplifir (EDFA) confgurations, single stage amplifirs, Amplifed Spontaneous Emission (ASE) light sources and single channel or few channel EDFAs.
M-5(980/125) offers a relatively low level of doping to simplify EDFA manufacturing processes by reducing the sensitivity of the amplifir output to the precise gain length.
M-12(980/125) gives high absorption levels to allow short gain lengths and reduced material costs.
M-12(980/80) is an 80µm variant, beneftting from the higher absorption of the standard
M-15(980/125) but allowing signifcantly longer mechanical lifetimes when used in small coil diameters, particularly important for small form factor EDFA designs such as mini EDFAs and micro EDFAs.
M-3(1480/125) is designed for pumping at 1480nm, accessing higher pump conversion effciencies than pumping at 980nm.
Advantages:
- High conversion efficiency
- High absorption variants available for short amplifiers and EDFAs
- 80μm variant for small coil diameter applications
Typical applications:
- Erbium Doped Fiber Amplifiers (EDFAs)
- Amplified Spontaneous Emission (ASE) light sources
- Single channel amplifiers
- Mini and micro EDFAs
