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.
