Abstract
The impact of employing a hybrid Raman/Erbium‐doped fiber amplifier (EDFA) in a transmission system is demonstrated by considering the optical signal‐to‐noise ratio (OSNR) performance. The gain flatness of hybrid Raman/EDFA is maintained below 1.2 dB from 1530 to 1565 nm through careful design of both amplifiers. The enhancement of OSNR is measured at around 5 dB, compared to the conventional EDFA approach with a 28‐dB span loss. © 2005 Wiley Periodicals, Inc.
