Abstract
- In this paper, the 50 Gbps next generation passive optical network stage 2 (50G- NGPON2) architecture is proposed via converging millimeter wave (MMWave) over fiber technology to meet the requirements of fifth generation (5G) fronthaul network such as enormous demand of high transmission rate and huge bandwidth. It uses the non-return to zero (NRZ) line code to generate pulse for 50 Gbps of data per channel, 28 GHz MMWave spectrum band over 60 km of bi-directional fiber span under the ITU-T G.9804 standardization. Two ideal erbium dopped fiber amplifiers (EDFA) with the gain of 10 dB and 5 dB respectively are used to amplify the signal on the transmitter side before transmission and receiver side after transmission. Outcomes of the proposed system demonstrate the network structure performance efficiency via Q-Factor (> 6), error rate, spectrums, and eye diagram. The variations of the Q-Factor for all optical network units (ONUs) during downstream and channels during upstream can be seen at the different fiber spans. Considering the scope of the future, in the area of digital processing, a single channel 50G-PON using 16-QAM is presented to improve the modulation and demodulation of MMWave spectrum.
