SFP-10/25G-CSR-S — SFP28 10/25 Gbps

The Cisco SFP-10/25G-CSR-S is a dual-rate SFP28 module supporting 10/25 Gbps over multimode fiber (MMF), offering a reach of 400 m over duplex cable with an LC (UPC) connector. Capable of automatically switching between 10 Gbps and 25 Gbps, it facilitates the coexistence of multi-generation equipment on a shared MMF infrastructure, within an operating range of 0 to 70 °C.

Unlike its SMF long-reach counterpart, the LR-S, this module targets short intra-campus or inter-room links over OM3/OM4 multimode fiber, ideal for data centers transitioning between 10G and 25G. Network teams value its ability to serve both existing 10G ports and new 25G ports without changing transceivers. Genuine Cisco hardware, manufacturer warranty.
