The introduction of WDM was the beginning of optical networking, as WDM grew to become the engineering of choice for fiber-optic bandwidth expansion.[24] The first to market which has a dense WDM system was Ciena Corp.
Routers: Routing is the whole process of selecting the network path through which the data packets traverse. Routers are products that forward these packets between networks to ultimately get to the desired destination. They insert efficiency to big networks.
