# Experimental Assessment of Real-time PDCP-RLC V-RAN Split Transmission with 20 Gbit/s PAM4 Optical Access

## TL;DR

This paper demonstrates real-time transmission of a 3GPP RAN split interface over 20 km using a high-speed PAM4 optical link, showcasing the feasibility of virtualized RAN deployments with high data rates.

## Contribution

It provides the first experimental validation of 3GPP split RAN interface transmission over 20 km with 20 Gbit/s PAM4 optics in real-time.

## Key findings

- Successful 20 km transmission at 20 Gbit/s
- Real-time operation of virtualized RAN interface
- Validation of high-speed PAM4 optical access

## Abstract

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.
