摘要：
In this paper, the transmission performance of 64 × 10 Gbps wavelength division multiplexing system using semiconductor optical amplifier (SOA) with 0.4nm channel spacing has been demonstrated with different modulation data formats. The suitability of various data formats like nonreturn to zero rectangular (NRZrectangular), nonreturn to zero raised cosine, return to zero raised cosine, return to zero rectangular, return to zero supergaussian and return to zero soliton for an optical transmission link at ‒40dBm signal input power is evaluated. The results have been carried out by evaluating the value of quality factor, bit error rate (BER), eye closure and received optical power. It is found that using NRZ-rectangular data format, the signal can travel up to a transmission length of 260 km with acceptable BER (1.10e-09) and Q-factor (15.0 dB), respectively. © 2019 De Gruyter.
