Dual- versus single-carrier configuration for 40 Gb/s coherent BPSK-based solutions over low dispersion fibers
21 March 2010
: We experimentally compare the performance of BPSK-based dual- and single-carrier coherent solutions at 40 Gb/s over NZDSF fiber. We show that the single-carrier solution is more tolerant to cross-nonlinearities induced by 10 Gb/s NRZ neighbors. ©2010 Optical Society of America OCIS codes: (060.1660) coherent communication; (060.4510) optical communication
