Abstract
A passive optical network system and method in which at least part of the data is optically transmitted through a single optical fiber using a wavelength division multiplexing technique, with a plurality of signals being carried through the fiber in each direction, a different wavelength being used for each of the multiplexed upstream and downstream signals. The system may be retrofitted into existing telecommunications system to provide a multi-fold increase in the available bandwidth of long-distance optical fiber transmission.
