Ultra-High Splitting Ratio Access Network with Optical Power Feeding Using a Hollow Core Fiber

We propose and investigate an ultra-high splitting ratio passive optical network (PON) using a hollow core fiber (HCF). An HCF is used for one of the downstream link for power delivery through feeding light, which powers an optical amplifier for the upstream that improves uplink power budget. We perform simulations to evaluate the maximum splitting ratio of the proposed HCF-based PONs. We show that the proposed system can support up to 4096 users in 25 Gbps non-return-to-zero (NRZ) intensity-modulation (IM) and direct detection (DD), as well as 1024 users in 25 Gbaud 16QAM transmission.
