Dual-hop LANs using a wavelength routing cross connect

The use of wavelength-division-multiplexing (WDM) may dramatically increase the traffic capacity in future local and metropolitan area networks. However, because of device limitations, the number of available wavelengths may initially be less than desired. As a result, spatial reuse may be required in order to obtain designs which will support a reasonable number of stations. There are several ways in which this may be accomplished (Matsumoto, …
