Ericsson RDH10275/1 Compatible 25GBASE-SR SFP28 for Baseband 6630 and 6620 Fronthaul

EdgeOptic's RDH10275/1 compatible is an Ericsson-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor SFP28 dual-rate 10G/25G SR transceiver. RDH10275/1 is Ericsson's ordering code for a 25GBASE-SR SFP28 used on Baseband units in 5G fronthaul and Single RAN deployments per Ericsson's hardware documentation. The module is programmed with Ericsson-recognized EEPROM vendor and part-number strings so the Baseband management plane reads the optic against its native transceiver table.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber, with 10GBASE-SR support per IEEE 802.3ae on dual-rate SFP28 host ports. Line signaling rate is 10.3125 Gbps at 10GBASE-SR and 25.78125 Gbps at 25GBASE-SR. Reach is 100 m on OM4 and 70 m on OM3. The 5G fronthaul application sits on top of the same Ethernet PMD with CPRI or eCPRI framing handled by the Baseband unit.

Optical path is 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget, LC/UPC duplex connector. Digital diagnostics are SFF-8472 compliant, exposing per-module temperature, supply voltage, TX bias, TX power and RX power on the standard SFP28 telemetry registers. Power dissipation is 0.3 W, the module is hot-swappable, and the operating temperature range is 0 to 70°C commercial.

RDH10275/1 sits on the 25G SFP28 fronthaul ports of Ericsson's RAN hardware, with the platform scope at the chassis-family level covering Baseband 6630 (CPRI and eCPRI fronthaul) and Baseband 6620 per Ericsson's hardware documentation. Ericsson Baseband-unit interface tables are updated with each RAN software release, so confirm the running Baseband software image against the Ericsson hardware description for the target unit revision before specifying the part for a deployment. Ericsson's official position on third-party optics in RAN is restrictive; the EdgeOptic compatible is programmed with Ericsson-recognized EEPROM so the optical-ID check returns cleanly on the Baseband management plane.

RDH10275/1 is the 25GBASE-SR short-reach variant (850 nm MMF) in the Ericsson RDH10275 ordering family. The /2 and /3 catalog entries are longer-reach variants on single-mode fiber at 1310 nm per third-party reseller listings. Match the catalog suffix to the optical class required for the link before ordering; verify against Ericsson Baseband documentation for the target unit. RDH10275/1 is the commercial 0 to 70°C variant. Extended-temperature (I-TEMP) coverage for outdoor Baseband cabinets is available on request as a separate SKU.
