Abstract

In this paper, the Er3+-doped optical fiber amplifiers (EDFA's) have been investigated experimentally, which are pumped by LDs at wavelengths of 1.45 μm and 1.47 μm. The results show that the signal light can also be amplified by the EDFA pumped at wavelength of 1.45 μm. A gain of 27 dB has been obtained for the EDFA's forwards and backwards pumped at wavelengths of 1.45 μm and 1.47 μm.
