All-optical aggregation and de-aggregation between 3 × BPSK and 8QAM in HNLF with wavelength preserved.

Abstract

All-optical aggregation and de-aggregation with wavelength preserved play an important role in a flexible optical network. In addition, it is also expected to apply in a network node that connects different networks and increases the channel utilization by freeing up the low-speed channel. In this paper, we proposed an aggregation and de-aggregation setup between three binary phase shift keying signals and 8-ary quadrature amplitude modulation signal using the nonlinear effect in high nonlinear optical fiber. Moreover, the bit-error rate of the signal is analyzed to evaluate the performance of the system by numerical simulation.
