Abstract
A counter-directional optical network having multiple channels includes a source module connected with at least two network nodes by a fiber ribbon including an array of optical fibers. Each channel includes at least one optical fiber. The source module includes multiple signal sources, each signal source connected with one of the channels and operable to transmit a source signal in a direction in the channel. Each network node includes a modulator for processing the source signal with a data input signal forming a message signal, a switch for selecting one of the channels to transmit the message signal and a receiver connected with one of the channels for receiving a message signal from another node. The message signal is transmitted to the receiver of a receiving node in a direction opposite to the transmission direction of the source signal via the channel connected to the receiver of the receiving node.
