Fibercore’s IsoGain™ (F-I) 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.

Fibercore’s MetroGain™ (F-M) 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.

The following volume discount schedule is automatically applied when ordering bare optical fiber: 6 - 50 m with 15 %, 51- 1,000 m with 22 %, > 1,000 m with 25 %. Discount only applicable towards continuous length of fiber.

Applications



F-EDF and EDF-Tx Erbium Doped Fibers

F-EDF erbium doped fibers provide the basic building block to fiber optic amplifiers used in broadband optical networks and CATV applications in the 1550nm fiber optic transmission window. These erbium doped fibers deliver gain efficiencies in excess of 3.5 dB/mW when pumped with a 980nm laser diode. Newly introduced are F-EDF-2 (replaces EDF-T6) that has a flat gain profile and F-EDF-5, suitable for metro EDFA applications.

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.
