A MULTIPLICITY OF SERVICES VIA A WAVELENGTH DIVISION ROUTER |
摘要 |
A communication arrangement where a head station is connected to a router and delivers a signal to the router that is adjusted to the granularity of the free spectral range (FSR) of the router. At a minimum, a signal is broadcast to all outputs of the router, to which network interface units may be connected, with a modulated carrier that spans as little as one FSR interval. Two independent signals are delivered to the network interface units by adding a second carrier that may be as close as at an adjacent FSR interval. In a telecommunication environment, the head station may be a central office-like station which serves a plurality of customers and which provides the expected private communication. Additionally, it provides new broadcast services, such as TV broadcast (much like cable systems currently do) and other multi-media services.
