Abstract
A bidirectional submarine transmission using unidirectional amplification transmits first and second communication signals bidirectional to each other over a repeater path with common end-to-end points, the repeater path includes a single unidirectional amplifier, the repeater path has a first branch path for the first communication signal through the single amplifier and a second branch path for the second communication signal through the single unidirectional amplifier, the first and second communication signals originating and leaving opposite ends of the repeater path, respectively.
