Overview

Due to significant developments in high transmission rate applications for big data analytics, cloud computing, and other next-generation 5G smart applications, today’s access networks are under a lot of pressure to meet the high bandwidth needs. In this work, a bidirectional high capacity of 160 Gbps utilizing hybrid time and wavelength division multiplexing passive optical network (TWDM-PON) is simulated and investigated via OptiSystem software. The fiber Bragg grating (FBG) in the receiver sector for both the optical line terminal (OLT) and optical network unit (ONU) is employed to reduce the effect of linear chromatic dispersion until given permission to enhance the distance communication system for a symmetric 160 Gbps E2-class (TWDM-PON). According to the results, the maximum achieved link distance with an outstanding bit error rate of 10 − 9 is around 40 km and 70 km for the system without and with dispersion compensation, respectively. This represents an enhancement of about 75% which can support the next-generation passive optical networks stage 2 (NG-PON2) with a splitting ratio of 1:256.
