ABSTRACT:
A method of multiplexing optical signals in a node of an optical network including as inputs a plurality of electrical signals, a plurality of laser transmitters, and as outputs a plurality of optical fibers, (a) generating clock pulses as a first clock frequency; (b) dividing the clock pulses respectively into a number of parallel trigger outputs; (c) sampling the electrical signals respectively by triggering on the parallel trigger outputs; (d) converting the sampled electrical signals to sampled optical signals by modulating respectively the laser transmitters with the sampled electrical signals and outputting respectively the sampled optical signals on the optical fibers; (e) combining the sampled optical signals onto a single optical fiber.
