Multiwavelength Optical Networks

Anticipating the imminent commercial deployment of the technology, Stern (electrical engineering, Columbia U.) and Bala, who manages a network networking company, explore wide-area wavelength-division multiplexing. They present four architecture categories in increasing order of complexity: shared channel networks, wavelength-routed networks, linear lightwave networks, and hybrid networks that are logically routed.
