“…The each separated modulated NRZ-OOK signal based on the used de-correlation technique accordingly by the used bitrate per channel with PRBS11 sequence has a constant bit-stream delay (Table II). [18]. Widely used FBG and DCF CD compensation methods are considered for comparison in our research.…”

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.

“…Dispersion can be of multiple types such as intra-modal dispersion, intermodal dispersion and polarization mode dispersion. In any single mode fibre (SMF), chromatic dispersion is one of the most worsening factors which cause the feasible transmission distance and maximum data rate to be diminished immensely [5]. Numerous procedures in various regions have been used that have shown signs of improvement at the recipient side.…”

With the growing demand for usage among Internet users, inventions related to increase in the capacity and bandwidth of transmission channels are more significant nowadays. This continuously growing demand can be fulfilled by using the optical fibre for transmission of signals instead of the wireless mode of transmission, due to the less nonlinearity present in the optical fibre. As every available mode has its own shortcomings so does the optical fibre. It suffers from dispersion and other linearities when long-distance transmission is considered. Hence, the field of invention is associated with the compensation of dispersion in optical fibre communication at higher bit rates of 50-80 Gbps for longer distances of 120 km. After their compensation, comparison of two photodiodes, that is, pin diode and avalanche photodiode has been done at these distinct bit rates in order to achieve the best suited photodiode. After the complete analysis of simulations in terms of quality factor and bit error rate, it has been observed that at distinct bit rates of 50-80 Gbps, the simulation model using avalanche photodiode exhibits superior performance to that of the pin diode. The comparison results show that the performance of the avalanche photodiode is around 11% better than the pin diode.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Optical fiber communication (OFC) provides us a very high bit rate data communication. There are different types of impairments and signal degradation mechanisms involved with this high speed communication system. In case of long haul communication, the most effective impairment is dispersion. It affects the signal very badly when signal travels a long distance. Different techniques are available to compensate dispersion. Not all of them are the same in performance. In this work, we study multiple dispersion compensation techniques and their performance measures and compare them with respect to the BER, Q-factor, Eye height, threshold etc. For this purpose, we used OptiSystem13 simulation software. Based on our analyses, we derive a conclusion on which technique is better for high speed long haul OFC networks.
