T640SW LTE Terminal Equipment for Optical Submarine Cable Systems
In order to meet the market needs of optical submarine sys-tems, NEC has developed the T640SW LTE terminal equip-ment that features an ultralarge-capacity/ultralong-distance transmission capability.
Paper Title (use style: paper title)
Because the transition between two codes does not return to zero in NRZ, it is not suited for high-speed transmission for protracted optical signals. We can employ two Mach– Zehnder modulators in RZ
