Dual-Rate 10/25G SFP28 Module

This Cisco SFP28 transceiver delivers dual-rate 10 Gbps and 25 Gbps connectivity for multimode fibre networks. It is built for data-centre switches and servers that require flexible bandwidth scaling. The hot-pluggable form factor simplifies deployment in existing SFP28 cages. It targets network engineers upgrading legacy 10G links to 25G without changing cabling infrastructure.

Verify LC Duplex MMF Compatibility

Confirm that your switch or server line cards support 25GBASE-CSR over multimode fibre with LC duplex connectors. Check the port configuration for SFP28 electrical interfaces and ensure the host firmware recognises dual-rate modules. Validate the link budget against your installed fibre grade and distance requirements before ordering. Incompatible cages or firmware revisions will prevent the module from initialising.

LC Duplex Connector Enables Direct MMF Patching

The integrated LC/PC duplex receptacle allows immediate patching to standard multimode fibre patch cords without additional adapters. This reduces insertion loss points and simplifies cable management in high-density panels. The single-module design covers both 10G and 25G speeds, lowering spare-part inventory compared to stocking separate transceivers. No extra licensing or software bundles are included with the hardware.

Questions about this item

Does the Cisco SFP-10/25G-CSR-S= module ship with cables or must they be purchased separately?

The module includes an LC/PC duplex interface for multimode fibre; patch cords are not included and must be sourced separately.

The part number shows 10/25G — which speed should I select for my link?

The SFP28 module auto-negotiates 10 Gbps or 25 Gbps depending on the connected switch port configuration.

What does the 25GBASE-CSR designation mean for actual deployment distance?

25GBASE-CSR defines operation over multimode fibre using an LC duplex connector for short-reach data-centre links.
