8-Channel wavelength division multiplexing (WDM) with zero BER

To meet an ever increasing demand on bandwidth and speed, wavelength-division-multiplexing (WDM) has become a promising networking choice in optical communication. High speed applications such as video conferencing, data browsing, video-on-demand, etc. has become very convenient and fast because of the use of optical networks. Besides optical interconnects, which play a vital role in networking, channels are also an important factor which multiplies the speed and applications. BER is a parameter which effects the performance of the overall system, hence, it should be minimized to a greater extent. This paper demonstrates the working of WDM using simulation software optisystem with an ideal case of zero BER.
