The exponential growth of data traffic related to the progress of newest technologies (e.g., 4K/8K live stream videos, virtual reality (VR) applications, etc.), new services, and a fast-growing number of end-users require higher bandwidth and increase of user bitrate, as a result pushing hard the telecommunication infrastructure for upgrading. Expected usage of more complex modulation formats in fiber optical link infrastructure for cellular network transmission and data center interconnections (DCI) are still affected with fundamental chromatic dispersion influence on the signal quality, which consequently increases bit error rate (BER). We experimentally demonstrate a real-time comparison of commercially used dispersion compensation techniques for 100 GHz spaced dense wavelength division multiplexed (DWDM) optical transmission system with a total transmission speed capacity of 160 Gbit/s.
