Erbium Doped Fibers provide the basic building blocks for fiber optic amplifiers more specifically Erbium Doped Fiber Amplifiers (EDFAs) used in broadband optical networks and CATV applications. The core of the fiber is doped with Erbium and is typically pumped with 980 or 1480 nm to produce gain around 1550 nm (C-Band) or 1590 nm (L-Band).

Features
Fibercore’s IsoGain™
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. The core composition of IsoGain has been engineered to generate a substantially flattened wavelength response that closely matches that of other leading fiber types. All model numbers with "F-I" in them are among the IsoGain family as well as F-EDF-2.
Low Absorption Fiber Available
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.
Fibercore’s MetroGain™
Fibercore’s MetroGain range is designed for high efficiency ‘Metro-style’ Erbium Doped Fiber Amplifier (EDFA) configurations, single stage amplifiers, Amplified Spontaneous Emission (ASE) light sources and single channel or few channel EDFAs. All model numbers with "F-M" in them are among the MetroGain family as well as F-EDF and F-EDF-5.
EDF-Tx Erbium Doped Fibers
The EDF-T3 C-band erbium doped fiber provides low splice loss, high strength enhanced overlap integrals and pumping at 980nm and 1480 nm. The EDF-T6 is optimized for use in L-Band EDFAs and provides high erbium peak absorption levels and low background loss. The EDF-Tx family features low background loss and excellent uniformity.
High Gain Efficiencies
These erbium doped fibers deliver gain efficiencies in excess of 3.5 dB/mW when pumped with a 980nm laser diode.
