Abstract

In this paper we observe experimentally the effects of C-band pump light in the performances of an Lband Erbium-Doped Fiber Amplifier (EDFA). An amplifier for C+L-bands in a parallel configuration of two EDFAs is
designed, and the inherent implications in its application to optical fiber communications systems. A new configuration is presented for decreasing the signal gain dependence in the L-band on the C-band residual power.
