Erbium Doped Fiber, Flat Gain Profile

The gain spectrum of F-EDF-2 (manufacturer P/N I-5 (980/125)) has been designed to generate a substantially flattened wavelength response that closely matches that of other leading fiber types. This intrinsic flatness and compatibility both simplifies the design of gain flattening filters (GFFs) and facilitates multi-sourcing by enabling the re-use of existing component stocks. Its core composition also promotes rapid mode-expansion during fusion-splicing, optimizing power output and noise figure and simplifying gain-module manufacture. This product offers an identical gain spectrum every time, with maximum batch-batch absorption variability just 0.00025 dB/m. This model replaces the legacy model F-EDF-T3.

This bare fiber does not include a protective fiber jacket. Standard pricing is per meter. The following volume discount schedule is applied when ordering continuous lengths of optical fiber: 10 - 49 m: 15%, 50 - 99 m: 22%, 100 - 499 m: 25%, and ≥ 500 m: 28%.

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.

F-EDF Series

F-EDF erbium doped fibers provide the basic building block to fiber optic amplifiers used in broadband optical networks in the 1550 nm transmission window. These erbium doped fibers deliver gain efficiencies in excess of 3.5 dB/mW when pumped with a 980nm laser diode. F-EDF-2 has a flat gain profile while F-EDF-5 is suitable for metro EDFA applications.
