“…Today, RoF and GPON technologies are promising solutions for supporting wireless internet users with high bandwidth, flexibility and straightforward evaluation. The RoF performance specification, which uses GPON architecture, has been utilised in [20,31] to analyse the system's physical capabilities in wireless internet transmission. Favourable results have been acquired at the fibres' maximum distance.…”

“…The authors in [31] examined the SCM-WDM-PON using a bi-directional reflector filter and periodic Arbitrary Waveform Generator (AWG) to provide uplink/downlink data via a single optical source. The downstream signal for the proposed scheme was modified via a laser diode Continuous Wave (CW) and reconstituted as an upstream signal in the optical network.…”

The 10-Gigabit Passive Optical Network (GPON), also known as (XGPON), is a key technology for the next generation of optical fibre communication systems which can improve reliability and data rate. However, the increment in the transmission distance and data rate will lead to increased dispersion. This paper proposes a model based on the Sub-Carrier Multiplexing/Wavelength Division Multiplexing-Radio over Fibre-10-Gigabit Passive Optical Network system (SCM/WDM-RoF-XGPON) for Radio Frequency (RF) using a conventional Optical Network Unit (ONU) with the Square Root Module (SRM) on the side of the receiver. It is connected to a central office Optical Line Terminal (OLT) via an access network for multi-channel optical fibre transfers with a distance of 80 km and at 10 Gbps data rate. The Optisystem 15 simulation software is used to evaluate the proposed system based on the Bit Error Rate (BER), Quality factor (Q-factor) and eye diagram. The proposed system of bidirectional fibre links uses 1270 nm and 1577 nm wavelengths for uplink and downlink transmissions, respectively. The performance is further enhanced through the use of SRM to compensate for the square law characteristics, making it suitable for providing broadband services. Due to the utilisation of SRM in the architecture, the reported results reveal a double enhancement in successful transition performance at an optical fibre length of 80 km distance. The BER displayed significant improvement (less than 1.00E-09) with SRM at 80 km; however, without SRM and at 50 km, the BER is less than 1.00E-09. Investigations have presented an enhancement in the Q-factor's effectiveness with the use of SRM, which helps to increase the XGPON length. When the length of the fibre is 80 km, the Q-factor is 6 with SRM, while it is 3.7 without SRM.

“…Under the generic term of NG-PON2, the working group has started an investigation on upcoming technologies with higher bandwidth utilization and able to solve the issues encountered in the 1G and 10G PON technology deployments. There are a few candidate to support NG-PON technology such as WDM PON [2], XLG PON [3], OFDM PON [4,5] and TWDM PON reviewed by FSAN working members.…”
