Expanding Optical Cable Capacity
Japan's NTT and NEC have announced that they have conducted a transmission experiment using a new fiber optic technology that they say could substantially increase the capacity of submarine cables. ◆ NTT developed the world's highest-capacity 192-core submarine cable system using multicore optical fiber (MCF), enabling a fourfold increase in transmission capacity without changing the submarine cable system. The transmission capacity of a single submarine cable has been increasing to meet the growing demand for global data traffic, requiring the continuous advancement of optical transmission systems and optical fibers. This paper discusses the submarine fiber that provides the best performance and cost.
