Circuits that establish a communication channel over an optical fiber and allow multiple laser wavelengths to behave as a single logical transmission channel. A sequence, or signature, is added to the data signal and acts as a timing reference at the transmitter and receiver. Coordinating this reference with adjacent circuits at the transmitter, when multiple circuits are used in parallel, enables the receiving circuits, in corresponding numbers to the transmitters, to reproduce the reference synchronization and to extract the transmitted data. The system elements include interconnected transmit circuits, each of which is coupled to a device that generates laser light at a specific wavelength, and are then conveyed through an optical fiber to multiple suitable arrangements of laser light receivers that separate and convert the laser light signals to independent electrical signals, to the interconnected receiving circuits that restore the original data sequence.
