VVDN’S O-RAN FRONTHAUL IP FOR BOTH DISTRIBUTED UNITS & RADIO UNITS

VVDN’s O-RAN IP or FrontHaul IP is a high performance, highly configurable IP interfacing 10/25/40G Ethernet IP (3rd Party) on the SFP side which is ideal for 7.2x Split O-RAN solutions and the IP is customizable for both Distributed Units (DUs) and Radio Units (RUs) with a rich feature set.

The FHIP is a packet-based transport that uses the eCPRI protocol to exchange the data between the DU and the RU which mainly carries the frequency domain digital IQ samples (U-plane) in both DL and UL directions, along with the C-plane and S-plane for synchronization (PTP). It also supports OAM via M-plane packets.

On the RU side the FHIP interfaces with VVDNs LowPHY IP on the user-side (towards the Antenna) and similarly QDMA based PCIe x8 Gen3 on the DU side of FHIP, that is towards the Core. The FHIP supports both compressed and uncompressed data.

Available ORAN Fronthaul IPs

Fronthaul IP for the DU
