Abstract

Recently, the use of erbium-doped fiber amplifiers (EDFAs) in amplitude modulated (AM) sub-carrier multiplexed (SCM) CATV networks has attracted considerable attention [1], [2], [3], [4], [5]. For AM SCM signals, AC gain tilt in the EDFAs leads to signal degradation through composite second order (CSO) nonlinear distortion [5], [6], [7], [8], [9], [10]. Therefore, the AC gain tilt needs to be controlled.
