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.

Claims

1. A method for bi-directional full duplex Gigabit Ethernet connectivity using a single conductor for data communication, comprising:

converting an electrical signal to be communicated in a first direction into a signal of a first wavelength to be communicated in the first direction using a first standard Gigabit Interface Converter device having an output and an input operating at a first wavelength;

converting the signal of the first wavelength to a signal of a second wavelength to be transmitted in the first direction; and

coupling the signal of a second wavelength on the single conductor for transmitting in the first direction.
