Abstract
We proposed an enhanced Reach Extender (RE) called Active Co-existence (ACEX) and investigate its performance with respect to XGS-PON system that co-exist with GPON and TWDM-PON system. The RE is consists of hybrid optical amplifier integrated (EDFA and SOA) with Co-existence Element (CEX) module which is installed at the Central Office (CO) together with the OLT system and act as a booster and pre-amplifier for the downstream and upstream optical signal respectively. The results show that the proposed ACEX is capable to support XGS-PON operation for a maximum distance of 35 km with 128 splitting ratio and up to 44 dB link loss.

The IP traffic is expected to grow at Compound Annual Growth Rate (CAGR) of 22% from 2015 to 2020, rapidly driven by high bandwidth demand and high-end applications and services such as High-Definition Television (HDTV) which evolves towards 4 K - 8 K resolution, Machine to Machine (M2M) communication and Internet of Everything (IoE) [1]
Due to the aggressive demand from the consumers and the need to expand the revenue by the network operators, the current optical access network should be upgraded by utilize co-existing PON technology with the Generation PON systems (NG-PON), capitalizing on the deployed optical distribution network (ODN) and optimizing the initial network investments
Summary
The IP traffic is expected to grow at Compound Annual Growth Rate (CAGR) of 22% from 2015 to 2020, rapidly driven by high bandwidth demand and high-end applications and services such as High-Definition Television (HDTV) which evolves towards 4 K - 8 K resolution, Machine to Machine (M2M) communication and Internet of Everything (IoE) [1]. Due to the aggressive demand from the consumers and the need to expand the revenue by the network operators, the current optical access network should be upgraded by utilize co-existing PON technology with the Generation PON systems (NG-PON), capitalizing on the deployed optical distribution network (ODN) and optimizing the initial network investments. An optical amplifier based GPON reach extender deployed underground and demonstrated an error free operation over 28 dB on distribution loss [10]. Another option is using an Optical-ElectricalOptical (O-E-O) as an inline RE which is located 80 km from the OLT providing 128 splitting ratio with 59 dB link loss budget [8]. We characterize the gain and Noise Figure (NF) of the ACEX, and analyze the performance of the extended XGS-PON system in terms of frame loss and throughput for various values of distances and splitting ratios
