“…al experimentally investigated the 25Gbps NG-PON system's performance for a 25 km reach by employing a differential phase-shift keying (DPSK) signal at downstream transmission and its conversion to optical duobinary modulation format at the ONU receiver. The receiver sensitivity of -29 dBm was observed for BER less than 10 -5 with a 1:64 split ratio [11].…”

The next generation passive optical network stage 2 (NG-PON2) is a broadcast network in which a large number of optical network units (ONUs) can be served using various network topologies. In this paper, a purely passive remote node (RN) design based on fiber bragg grating (FBG) is presented for the bus topology of a high split NG-PON2 system. The performance of the proposed node has been analysed for a symmetric 80 Gbps NG-PON2 system serving 1024 ONUs in terms of bit error rate (BER) and optical signal to noise ratio (OSNR). The working of the proposed node has been explained with the optical frequency spectrums for downstream and upstream signals. The observed OSNR levels for the ONUs operating at the 1st RN is 84.8743dB which decreases to 75.7973dB for the ONUs connected to the 8th RN. The BER level < 10-9 for both upstream and downstream confirms the correct working of the proposed node in the NG-PON2 system.
