G654 Non-Zero Dispersion Shifted Single-mode Fibre is designed specially for long-haul optical transmission systems. It makes performance optimization in both C band (1530-1565nm) and L band (1565-1625nm). Its enlarged effective area suppresses nonlinear effect in the process and increases nonlinear tolerance for transmission system. G654 Non-Zero Dispersion Shifted Single-mode fibre reduces attenuation in both C band and L band. The fibre fully meets the demands for transmitting signal with high speed, high capacity and extended networking distances over one single fibre.e single fibre.
