Sband amplification is an important area of optical communications research, focusing on meet ing the everincreasing demands for traffic bandwidth as the C and Lbands approaches to their limits. In this paper a novel method of providing an Sband optical amplifier with a flat gainbandwidth is proposed. The proposed method utilizes a Depressed Cladding Erbium Doped Fibre together with a Tunable Mach Zehnder Filter as to generate a flat amplification bandwidth of 12 nm stretching from 1492 to 1504 nm. The average gain value is approximately 24.21 dB, with a peak to peak fluctuation of 0.83 dB and a noise figure ranges from 7.13 to 10.94 dB for input signals of 1484 to 1510 nm.
