Abstract

A co-pumped Erbium-Doped Fiber Amplifier (EDFA) which consists of home-made 1480 nm pigitaled LD's and erbium doped fiber (EDF) has been developed. A small-signal gain of 32 dB of the EDFA has been obtained (fiber to fiber net gain is 27 dB). The saturation power and maximum power of fiber are 2.5 dBm and 10 dBm, respectively, while the gain bandwidth is greater than 25 nm.The gain and bandwidth characteristics of the EDFA are studied. Effects of Amplified Spontenous Emission (ASE) on measurement are discussed.
