This article analyzes experimentally the limitations observed in a 45 km Raman amplified 4 × 40 Gb/s transmission system operating under multiple pump and single high pump power configurations. A signal‐to‐noise ratio of 19.2 dB, an extinction ratio of 10.4 dB and a jitter of 1097 fs are achieved for moderate pump powers and higher order stimulated Brillouin scattering lines give rise to system degradation for pump power levels more than 0.5 W. © 2012 Wiley Periodicals, Inc.
