4X5Gbit/s Optical Time Division Multiplexed Nonlinear Transmission Over 205km,

Abstract : In order to fulfill the demand for increasingly sophisticated and bandwidth intensive services, telecommunications operators will require flexible optical transmission networks which will operate at higher data rates than those installed to date. At present, the maximum data capacity of installed optical systems is limited by the bandwidth of the electronics in the terminal and repeater equipment (currently around 2.5Gbit/s).
