摘要：

Wavelength division multiplexing (WDM) technique plays a vital role in optical fiber communication. In this paper, a 4 x 1 WDM system has been developed with Vertical Cavity Surface Emitting LASER as optical source for each input. The performance analysis has been carried for Non Return to Zero (NRZ), hyperbolic secant, Gaussian and impulse generators over complex WDM optical fiber up to 50 km with less attenuation of 0.2 dB/Km. The Signal to noise ratio of received signal through Avalanche Photo diode in the receiver is calculated. This work identifies the best pulse generator with reduced noise performance suitable for the proposed system. The proposed system is modeled in optisys13 and insightful discussions are provided from the simulated results.
