摘要：

40 Gbps WDM Systems using super-Gaussian RZ pulses have been studied by numerical simulation to optimize their performance. The assumption of standard single mode fiber is valid when existing WDM systems are required to upgrade their performance to 40Gbps. It is shown that the standard single mode fiber can transmit optical. signals over 720 kin (Q > 10) by optimizing optical and electrical filter characteristics at the receiver and by compensation of dispersion. However, it is also shown that +/- 0.3% dispersion compensation tolerance per span (80 km) could prohibit transmitting over 320km (Q > 10). In addition; a duty cycle of less than 0.4 degrades system performance significantly.
