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).
