Abstract:
1. A multiport network hub comprising: a plurality of transceiver boards, each having a network interface for connection to a network, a switch circuit operatively connected to the network interface, at least one optical transmitter for receiving signals from a network via the network interface and transmitting optical communications signals, at least one optical receiver matched with the at least one optical transmitter for receiving and detecting an optical communications signal and generating a signal to the network via the network interface, and a processor operatively connected to said switch circuit for controlling same; a bus interconnecting each processor; a wavelength division multiplexer operatively connected to each optical transmitter for multiplexing the optical communications signals into a multimode wavelength division multiplexed optical communications signal; and a demultiplexer operatively connected to each optical receiver for receiving and demultiplexing multimode wavelength division multiplexed optical communications signal into a plurality of demultiplexed optical communications signals.
