Pre-, post, symmetric1 and 2 compensation techniques with RZ modulation

The capacity of optical communication systems is rising exponentially in order to follow the rapidly increasing demand for data traffic. Limitations due to dispersion and nonlinearities in the optical fiber become more stringent for higher bit rates. To meet the growing demand of capacity for long haul communication system and to improve the transmission quality by minimizing the signal degradation the comparison of different modulation formats i.e NRZ and RZ with different dispersion compensation techniques pre, post and symmetric onto the link of 32 × 10 Gb/s is done.
