NOKIA (Alcatel) compatible SFP-25G-SR Description
EdgeOptic's SFP-25G-SR compatible is a Nokia-coded 25GBASE-SR SFP28 transceiver built as a direct replacement for the Alcatel-Lucent / Nokia SFP-25G-SR. The module is programmed with Nokia-recognized EEPROM so Nokia SR OS carrier-router and aggregation-switch platforms read it as an approved optic. Confirm your specific interoperability against the Nokia transceiver guide for your SR OS release before bulk deployment.
Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber: 100m on OM4 or OM5, 70m on OM3. Line signaling rate is 25.78125 Gbd, with dual-rate support from 8.5 to 25.78 Gbps so the module also operates at 10GBASE-SR on downshifted 10G ports. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB with host RS-FEC per IEEE 802.3by Clause 108. Duplex LC/UPC, DOM per SFF-8472, 0.3W typical power. Operating case temperature is 0 to 70 degrees Celsius.
SFP-25G-SR is the Nokia part number used across the SR OS 25G SFP28 portfolio. On carrier routers it appears in the Nokia 7750 SR service router family (7750 SR-1, SR-7, SR-12 with 25G-capable MDA and IMM cards). On the aggregation side it sits in the 7250 IXR interconnect router family. On service-aggregation switches it is used in the 7210 SAS platform family for 25G SFP28 ports; consult the Nokia 7210 SAS product datasheet for your specific variant to confirm line-card support. Platform qualification at chassis-family level is confirmed from Nokia transceiver documentation; verify the exact line card or media adapter against the Nokia compatibility matrix for the SR OS release you are running.
The module is the same physical optic that Alcatel-Lucent catalogued as AL-SFP-25G-SR before the 2016 Nokia merger. Post-merger Nokia documentation drops the AL prefix; the bare SFP-25G-SR part number is the canonical form on Nokia OneStore and on current SR OS release notes. Legacy purchase orders and spare-parts records that still reference AL-SFP-25G-SR can be satisfied by the same compatible. Note that Nokia OmniSwitch enterprise switches use different Nokia optic part numbering, so this module is scoped to the SR OS platform family.
DOM registers for transmit power, receive power, supply voltage, laser bias and module temperature are exposed through standard SFF-8472 access. On SR OS, DOM values surface through the standard port optical monitoring tools in the SR OS management CLI; refer to the Nokia transceiver guide for your release for exact command syntax. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112 before dispatch.

Frequently Asked Questions
Will the EdgeOptic SFP-25G-SR be recognized on Nokia 7750 SR and 7210 SAS without an unsupported-optic warning?
The module is coded with Nokia-recognized EEPROM, so Nokia SR OS platforms identify it against the native Nokia optic table. Because Nokia's SR OS release cadence can add or change transceiver entries in the compatibility matrix, confirm your specific SR OS release against Nokia's transceiver guide before bulk deployment. EdgeOptic can provide a sample for pre-qualification on request.
Is the Nokia SFP-25G-SR the same part as the Alcatel-Lucent AL-SFP-25G-SR on older purchase orders?
Yes. Nokia acquired Alcatel-Lucent in 2016 and consolidated the optic catalogue. AL-SFP-25G-SR was the Alcatel-Lucent prefix for the same 25GBASE-SR SFP28 that Nokia now catalogues as SFP-25G-SR. Any legacy spares record citing AL-SFP-25G-SR maps to this compatible. The optical specification is identical.
Can the Nokia SFP-25G-SR downshift to 10GBASE-SR on mixed-speed 10G and 25G deployments?
The module supports dual-rate operation from 8.5 to 25.78 Gbps, which covers 10GBASE-SR at 10.3125 Gbd and 25GBASE-SR at 25.78125 Gbd. Whether a given Nokia port accepts the downshifted rate depends on the line card or MDA speed-mode configuration in SR OS. On cards that support per-port 10G or 25G modes, the optic operates at whichever rate the port is configured for.
Does the SFP-25G-SR work on Nokia OmniSwitch enterprise switches as well as on the SR OS platforms?
The SFP-25G-SR part number is the SR OS family optic (7210 SAS, 7250 IXR, 7750 SR). Nokia OmniSwitch uses a different Nokia optic catalogue with its own OS-family part numbers. For OmniSwitch 25G deployments, confirm the correct OmniSwitch part number with your Nokia account team or contact us for an OmniSwitch-scoped compatible.
