Patent ID: 8600238

Claim:
A method for bi-directional data connectivity over a single optical fiber, comprising: receiving, at a first Gigabit interface Converter, a first electrical signal to be communicated in a first direction, the first Gigabit Interface Converter including a transmitter and a receiver operating at a first wavelength; converting, using the first Gigabit interface Converter, the first electrical signal to a first optical signal of the first wavelength; communicating the first optical signal of the first wavelength from the transmitter of the first Gigabit Interface Converter to a first wavelength converter, the first wavelength converter including a second Gigabit interface Converter coupled to a third Gigabit Interface Converter, the second Gigabit Interface Converter including a receiver operating at the first wavelength, and the third Gigabit interface Converter includes a transmitter operating at a second wavelength, the second wavelength being different from the first wavelength; converting, using the first wavelength converter, the first optical signal from the first wavelength to the second wavelength; and coupling the first optical signal of the second wavelength to an optical fiber to transmit the first optical signal in the first direction.
