Abstract

We proposed a novel dispersion compensation scheme based on relative phase detection of two SSB components of CS-RZ transmission code. These two components have NRZ pulse shape. Chromatic dispersion was detected by using 43-Gbit/s comparator HEMT ICs. The proposed technique successfully detected signs of chromatic dispersion and has sensitivity of 0.16-ps/nm/mV. Furthermore, the use of SSB-DD technique enabled us to achieve a wider dispersion tolerance (65-ps/nm) than that of a conventional CS-RZ signal.
