SFP-10/25G-CSR-S Dual-Rate Transceivers – One Module, Two Speeds, Endless Possibilities


In modern networks, speed and flexibility are key. Instead of replacing hardware every time your speed requirements change, what if you had one optical transceiver that works at both 10G and 25G?

That’s exactly what SFP-10/25G-CSR-S Dual-Rate Transceivers deliver.


What Does “Dual-Rate” Mean?

Dual-rate transceivers can operate at two different speeds—in this case, 10Gbps and 25Gbps—using the same module.

  • 10G Mode – Ideal for current network needs or legacy systems.

  • 25G Mode – Ready for future network upgrades without changing the hardware.


What is “CSR-S”?

  • CSR stands for Cisco Short Reach—optimized for slightly longer short-range connections than standard SR modules.

  • -S indicates it’s a Cisco-specific part number, but similar versions are available from multiple vendors.

  • Typical reach: Up to 300 meters on OM4 multimode fiber.


Why It’s a Game-Changer

  1. Cost-Effective Upgrades – Upgrade your network speed without replacing all optics.

  2. Inventory Simplification – One module covers both 10G and 25G needs.

  3. Future-Proofing – Deploy now at 10G, switch to 25G later.


Where is it Used?

  • Data Centers – Server-to-switch and switch-to-switch links.

  • Campus Networks – Connecting aggregation and core layers.

  • Enterprise Networks – Gradual speed upgrades without large capital investment.
