Although 16-PSK modems are potentially 1 dB more power-efficient than 8-PSK, at 2.5 b/s/Hz they are more susceptible to channel and modem impairments. 8-PSK with trellis coding is a suitable solution ref.: Bell Telephone System Technical Publications: Monograph B, Issue 1 http://www.albertiglesias.es/library/bell-telephone-system-technical-publications-monograph-b-issue-1.

For the synchronous case, the pulses in each tributary all rise and fall during the same time interval. For the plesiochronous case the rise and fall times of the pulses in each tributary do not coincide with each other. The plesiochronous designs have been globally deployed, but the synchronous systems are rapidly gaining acceptance and will become prominent in the near future epub. For three inputs there are fifteen outputs of which three are degenerate. Figure 8.44 shows a situation where a WDM data channel, say ten channels at 2.5 Gb/s, is mixed with two pump signals to change the WDM channel frequency. Clearly, care must be taken in choosing the pump frequencies so that there is enough separation between all the input and output frequencies. Some references in the literature describe four-wave mixing as a process in which three input waves mix to produce a fourth desired signal (plus several unwanted signals) , e.g. Bell telephone system download here Bell telephone system technical.
