We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution against cross-nonlinearities induced by 10Gb/s neighbor channels.
We experimentally compare the performance of BPSK-based dual- and single-carrier coherent solutions at 40 Gb/s over low-dispersion fiber. We show that the single-carrier solution is more tolerant to cross-nonlinearities induced by 10 Gb/s neighbors.
We present a simulation tool based on the Multicanonical Monte Carlo (MMC) method to characterize the statistical properties of bit patterning in semiconductor optical amplifiers (SOAs). Our tool estimates the conditional probability density functions (PDFs) of marks and spaces of the received signal. We introduce an experimental technique to directly measure the conditional PDFs of the received marks...
