BI-DIRECTIONAL SINGLE FIBER TRANSMISSION USING WAVELENGTH CONVERSION

摘要

Disclosed methods for transmitting bi-directional optical signal traffic over a single fiber include generating, by transponders at a first location, optical signals having wavelengths within a first wavelength band, converting the generated optical signals to optical signals having wavelengths within a second wavelength band for transmission to a second location, receiving, at the first location from the second location over a single fiber cable between the first and second locations, optical signal traffic comprising optical signals in the first wavelength band, and providing the received optical traffic to the first transponders. The methods also include merging, onto the single fiber cable by a Y-cable at the first location, the optical signal traffic converted for transmission and the optical signal traffic received from the second location. The methods also include converting, at the second location, the transmitted optical signal traffic to optical signals having wavelengths within the first wavelength band.
