Abstract

In this paper hybrid optical amplifier is investigated by cascading configuration of distributed fiber Raman amplifier and Erbium doped fiber amplifier for 64 X 10-Gb/s dense wavelength division multiplexing operating at 100-GHz channel spacing. The main idea behind the investigations is to examine the optical link of Wavelength Division Multiplexing system using different types of amplifier like EDFA amplifier, RAMAN amplifier and their Hybrid configuration. At the input power of 3 mW and with the variation in the Raman fiber length (11, 15, 17 and 20 km) of Raman amplifier having two Raman pumps, a flat gain of > 30 dB is obtained in optical signal wavelength range 1540 nm to 1589.28 nm with gain flatness of 4.5 dB and noise figure < 0.8 dB. Also, using four Raman pumps a gain of more than 50 dB and gain bandwidth up to 34 nm are achieved. The gain ripple after length of 80 km and noise ripple after length 100 km of hybrid amplifier is found to be stable.
