Alcatel-Lucent / Nokia 472063A FOSG Compatible 10GBASE-SR SFP+

Alcatel-Lucent / Nokia's 472063A FOSG is a short-reach SFP+ optical transceiver originally fitted on IP/MPLS routing platforms such as the Nokia 7705 SAR and 7750 SR, and also used on 7450 ESS line cards that accept SFP+ pluggables. EdgeOptic's compatible version rebuilds the module from the same reference design as the 10G-SFP-300, so the optical budget, wavelength plan, and host electrical interface match the original Nokia part 1:1.

Optical spec: 850 nm VCSEL transmitter, 850 nm PIN receiver, 6.1 dB guaranteed link budget, dual LC interface over multimode fiber. That delivers 300 m on OM3 and 400 m on OM4. The module runs at 10.3125 Gbps for 10GBASE-SR (IEEE 802.3ae Clause 52) and also carries CPRI rates up to option 8 (10.1376 Gbps) on 7705 SAR fronthaul ports configured for RRU/BBU interconnect. DDM/DOM telemetry per SFF-8472 reports Tx power, Rx power, bias current, supply voltage, and module temperature across the 0–70°C commercial range.

EEPROM is programmed with Nokia-recognised vendor strings so TiMOS and SR OS read the module as an approved part on 7705 SAR-M, SAR-X, and 7750 SR-7 / SR-12 chassis. CPRI line rate selection is driven by the platform's port configuration rather than by the optic, so confirm the host port mode (Ethernet vs. CPRI) before deployment. For C-RAN fronthaul, pair the module with short indoor OM3 or OM4 runs inside the shelter and verify both ends of the link use matching optics to keep the optical budget symmetric. Most 472063A FOSG deployments sit inside a BBU cabinet or MOR shelter, so patch lengths are well under the 300 m OM3 ceiling and leave comfortable margin against connector insertion loss.

The module is CE / RoHS certified and compliant with SFF-8431 / SFF-8432 SFP+ MSA definitions. DDM alarm thresholds are pre-programmed to mirror the Nokia factory values, so existing fronthaul monitoring and syslog pipelines continue to trigger on the same Rx-power and temperature boundaries without retuning.
