In this work, we experimentally assess the transmission of a PDCP-RLC virtualised RAN split interface through a commercial XGS-PON system. We investigate the impacts of DBA on the uplink and packet jitter on the downlink.

We successfully demonstrate a transmission of a high layer split mobile interface for cell-less, high-speed train network applications using a commercially available XGS-PON. Operation is also demonstrated for a GbE interface.

We experimentally demonstrate real-time, end-to-end transmission of 3GPP's option 2 functional split RAN interface with virtualized central units through up to 20km using a 20Gbit/s PAM4 link and 10GHz bandwidth optics.
