Product overview

25G SFP28 SR is designed for 70m OM3 / 100m OM4 links using Duplex LC. Selection must confirm the host form factor, electrical interface, PMD, FEC, fiber mapping, power and thermal limits, software version and the remote endpoint; the model name alone does not establish interoperability.

  • SFP28 SR form factor for the defined host-port direction.

  • Duplex LC interface for 70m OM3 / 100m OM4 links.

  • Parallel multimode optical transmission; confirm the exact fiber or cable assembly before ordering.

  • Validate host coding, FEC, diagnostics, power, thermal behavior and long-duration stability.

Selection and deployment notes

  • Before ordering 25G SFP28 SR, confirm the exact host, software, port mode, reach, fiber or cable, connector, FEC, temperature, quantity, compatibility coding and delivery version.

Selection FAQ

25G SFP28 SR selection questions

How far will 25G SFP28 SR run on OM3 versus OM4?

The specification lists 70m OM3 / 100m OM4. Multimode reach is bounded by modal bandwidth, so the fiber grade already in the ground decides the usable distance rather than the module. Re-check the loss budget whenever patch panels or splices sit in the path.

Can 25G SFP28 SR be used over single-mode fiber?

No. 25G SFP28 SR is a multimode transceiver on Duplex LC; driving it into single-mode fiber loses far too much power to close the link. Match the module to the installed fiber, or select a single-mode PMD instead.

What do I need to specify to request a quote for 25G SFP28 SR?

Give the host vendor, model and software version at both ends, the SFP28 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 25G SFP28 SR also state the installed fiber grade, the Duplex LC trunk type and the measured link distance. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
