ABSTRACT
The demand for ultra-high capacity transmission networks led to intensive development and research on Tere-bits/s (Tb/s) transmission over long distance that would occupy minimum aggregate bandwidth. Thus, there is aneed for (1) modulated channels that have aminimum bandwidth and are optimum in ISI with the maximum possible symbol rate reaching the limits of electronic processing and optical technology, and (2) multiple channels whose lightwave carriers are commonly generated and synchronized with the original laser source, the comb-generated laser lines.
