Abstract
In a system for communicating optically encoded data among a network of nodes, the nodes are connected to each other by optical transmit and receive fibers. Each node includes a laser, a transmitter, and a receiver connected to the transmitters of the other nodes by a fiber stretcher. The rate at which the laser generates light pulses is controlled by a frequency control signal supplied to an oscillator connected to the laser. The delay from the transmitters to the receivers is controlled by a phase control signal supplied to the fiber stretcher connected to the receive fiber. The transmitter connected to the transmit fiber selective delays the pulses into a plurality of time multiplexed channels. The receiver connected to the fiber stretcher selectively detects the pulses in the time multiplexed channels while all of the pulses of all of the nodes are globally synchronized in all of the time multiplexed channels in frequency and phase using the frequency and phase control signals.
