New trends in high speed networking

Convergence of information and communication technology (ICT) has met the large demand of voice, data, video and internet. The necessity of high speed network between computer to computer, computer to business houses and industrial users is the current requirement. The high speed network in advanced countries has increased from 40 Gbps to 40 Tbps. Such signals can not be processed electronically due to low signal to noise ratio. Hence, new technology based on optical-optical multiplexing using lasers as transmitters and photo diode as receiver via optical fiber medium has been successfully developed now a days.
