ABSTRACT:
A communications network comprising a plurality of "subnetworks" multiplexed onto a single communications medium. A separate group of NIU's communicate on each predetermined "subnetwork", and each NIU also includes a tunable transmitter for transmitting data to NIU's of other subnetworks. Data from a user equipment is transmitted via the tunable transmitter if it is destined for an NIU from another subnetwork, and via a fixed transmitter if it is destined for an NIU on the same subnetwork. In one embodiment, fiber optics is utilized in order to provide a high speed network with tunable lasers.
