SYSTEM AND METHOD FOR INCREASING CAPACITY OF UNDERSEA CABLES

摘要

A method of increasing usable bandwidth on a long-haul cable system having at least one optical fiber, the method comprising the steps of: (a) effecting counter-propagating first ad second signals of different bands on a common long-haul optical fiber having cascading optical amplifiers; and (b) band amplifying the first and second signals while reducing BRS in the bands.
