Performance evaluation of 10gbit/s, for single and 4-channel optical transmission system at 1550nm using semiconductor optical amplifier / Norjuzaila Abdul Hadi

A performance evaluation of optical transmission systems operating at 10 Gbit/s, for single and 4-channel in the 1550nm window of standard single-mode fibers is investigated experimentally. It is shown that, for 90km, the use of a semiconductor optical amplifier, with an unsaturated gain of 26dB, degrades the receiver sensitivity by 2.7dB. By adopting a multichannel WDM technique, the transmission capacity can be expanded without increasing the data speed and the chromatic dispersion effect. The OptSim simulator was used to model the structure, to assess the behavior and performance of the transmission system [6]. Parameters such as Q factor and bit error rate (BER) were calculated and have been confirmed experimentally using eye diagram technique. From this simulation, it is confirmed that the SOA is applicable for WDM transmission system with high bit rate because of its inherent wide bandwidth [1].
