Patent ID: 7840138

Claim:
A method for bi-directional full duplex Gigabit Ethernet connectivity using a single optical fiber for data communication, comprising: converting a first electrical signal to be communicated in a first direction into an optical signal of a first wavelength to be communicated in the first direction using a first Gigabit Interface Converter having an output and an input operating at the first wavelength; converting the optical signal of the first wavelength to an optical signal of a second wavelength to be transmitted in the first direction; and coupling the optical signal of a second wavelength to the single optical fiber for transmitting in the first direction, wherein the step of converting the optical signal of the first wavelength to the optical signal of the second wavelength to be transmitted in the first direction comprises: electronically coupling a second Gigabit Interface Converter having a receiver and a transmitter operating at the first wavelength to a third Gigabit Interface Converter having a receiver and a transmitter operating at the second wavelength, wherein the optical signal of the first wavelength to be communicated in the first direction is inputted into the receiver of the second Gigabit Interface Converter and is converted into a second electrical signal, said second electrical signal is electrically coupled to the third Gigabit Interface Converter which converts the second electrical signal into the optical signal of the second wavelength that is outputted through the transmitter of the third Gigabit Interface Converter.
