Abstract
Gigabit Ethernet connectivity is realized using off-the-shelf GIGABIT INTERFACE CONVERTER transceivers, wave division multiplexer/demultiplexers, and a single optical fiber. Simultaneous and bi-directional optical communication over a single optical fiber connecting two or more nodes is achieved by using at least one GIGABIT INTERFACE CONVERTER transceiver having at least one optical signal output and an optical signal input that are of different wavelengths from each other.
