ABSTRACT:
A land-based cable station is provided for interfacing with first and second undersea transmission segments of an undersea optical transmission system. At least one first bypass optical transmission path is provided for selectively coupling reflectometry probe signals and backscattered and reflected signals located at a prescribed wavelength from a first interface device to a second interface device. At least one second bypass optical transmission path is provided for selectively coupling reflectometry probe signals and backscattered and reflected signals located at a prescribed wavelength from the second interface device to the first interface.
