SFP-25G-SR-S — SFP28 25 Gbps

The Cisco SFP-25G-SR-S is a fixed 25 Gbps SFP28 module designed for short-reach applications, achieving 100 m over multimode fiber (MMF) via LC duplex (UPC) connector. Compliant with the IEEE 25GBASE-SR standard, it is optimized for high-density intra-datacenter links at a fixed 25G rate, with an operating range of 0 to 70 °C.

This transceiver is the natural choice for 25G Spine-Leaf architectures running on an existing OM3 or OM4 MMF infrastructure where a fixed 25G rate (without 10G auto-negotiation) is required. Its 100 m reach covers standard inter-rack and inter-row distances. Genuine Cisco hardware, manufacturer warranty.
