Abstract
The optical amplification gain of an optical amplifier consisting of an optical amplifier unit and a single-mode erbium-doped fiber can be optimized when the length of the fiber L in meters and the optical absorption in dB/meter of the fiber per unit length at a wavelength of 1.53 .mu.m satisfy the relationship that L.times.y is in the range from 70 to 170 dB by appropriately selecting the doping level of the glass with erbium and the length of the fiber.
