Sažetak
The paper presents the comparative investigation on non-return-to-zero and return-to-zero modulation formats for optical inverter gate at 100 Gbit/s. Various performances as eye pattern, extinction ratio and bit error rate at different bit-rate are compared based on suitability of data formats. It indicates that return-to-zero pulses are distorted in a similar pattern, therefore bit error rate is better than non-return-to-zero format. The non-return-to-zero is more affected by non-linearity of semiconductor optical amplifier hence the bit error rate is degraded and extinction ratio is improved.
