Modulation formats for 40 and 100 Gb/s transmission are compared based on OSNR tolerance. Implementation considerations are highlighted. Propagation penalty as a function of optical dispersion compensation is studied for 112 Gb/s DP-QPSK.

The performance of asynchronous coherent time-spreading OCDMA systems is evaluated semi-analytically and the results are compared with those of spectral coding OCDMA systems using ultra-short pulses. The fundamental multi-access interference limited performances are predicted to be identical.

We propose an all-optical demultiplexing scheme for quaternary amplitude signals which employs fiber-based optical gates and we test it by simulations. Results suggest this scheme is suitable to be applied in metropolitan area networks.
