Fronthaul, Optics & Management

Fronthaul InterfaceSealed optical fronthaul ports: CPRI/eCPRI; SFP+/QSFP-class depending on generation
Optical Form FactorSFP+ / SFP28 / QSFP28 by AIR generation
Optical SpeedCPRI/eCPRI 10 / 25 / 100 Gbit/s depending on model
Optical ConnectorLC duplex or MPO for QSFP-class links
Optical ReachTypical 10–20 km SMF
Known Optical Part NumbersEricsson-approved AIR fronthaul optics; exact module PN must match KRD hardware and RAN Compute interface.
Synchronization / ManagementService / maintenance interface; synchronization is normally transported over fronthaul
