Ericsson RDH10265/1 Compatible SFP+ 10GBASE-SR and CPRI Transceiver

RDH10265/1 is Ericsson's SFP+ transceiver for multimode CPRI fronthaul and 10GBASE-SR Ethernet links in radio access network infrastructure. The RDH-series part numbering is specific to Ericsson's Radio Base Station (RBS) and Baseband unit platforms, where the module provides the optical interface between the baseband processing unit and the remote radio head over multimode fiber. EdgeOptic's compatible module carries Ericsson-recognized EEPROM coding, so it registers correctly in the Ericsson element manager without manual intervention or software overrides. The /1 suffix in the part number designates the commercial-temperature variant (0 to 70 °C), rated for indoor Baseband unit installations and climate-controlled equipment shelters.

The transceiver operates at 850 nm using a VCSEL transmitter and PIN photodiode receiver, with an LC duplex interface and 6.1 dB guaranteed link budget. Reach is 300 m over OM3 multimode fiber and 400 m over OM4, with actual distance depending on the installed fiber plant and total connector insertion loss. Supported CPRI line rates include option 2 (1228.8 Mbps), option 3 (2457.6 Mbps), option 5 (4915.2 Mbps), option 6 (6144.0 Mbps), option 7 (9830.4 Mbps), and option 8 (10137.6 Mbps). OBSAI RP3 rates at 1.536, 3.072, and 6.144 Gbps are also supported for legacy fronthaul configurations. For standard Ethernet operation, the module runs 10GbE at 10.3125 Gbps per IEEE 802.3ae. The active line rate depends on the port configuration in the Ericsson baseband unit, not on the module itself, as the SFP+ transceiver is rate-agnostic within its supported range.

DDM/DOM diagnostics are active on insertion, reporting optical power levels, temperature, bias current, and supply voltage to the Ericsson management plane for proactive link monitoring. The module conforms to SFF-8432 MSA and is CE/RoHS certified. Ericsson also lists the RDH10265/3 for industrial-temperature fronthaul deployments (−40 to +85 °C), typically required for outdoor macro cell sites where the baseband or interface unit is mounted in an exposed equipment cabinet without active climate control. Distance calculations assume standard OM3/OM4 multimode attenuation at 850 nm.
