Cisco SFP-25G-SR-S= 25GBASE-SR SFP Module | Multimode, Data Center — SFP-25G-SR-S=

Move 25 GbE traffic across short-reach multimode fiber with a compact Cisco SFP module designed for dense switching environments. The SFP-25G-SR-S= supports 25GBASE-SR connectivity, making it a practical choice for data center uplinks, leaf-spine fabrics, and server aggregation where high port density and consistent short-distance performance are priorities. This module is built for teams that want to keep optics aligned with the job at hand. Rather than over-specifying long-reach optics for short links, 25GBASE-SR gives you the right balance of speed, reach, and cost discipline for multimode infrastructure. It fits naturally into environments where switch ports are scarce, cable paths are short, and operational simplicity matters. Cisco optics are often selected when compatibility, lifecycle confidence, and deployment consistency are worth paying for. For infrastructure teams standardizing on Cisco switching, this module helps maintain a clean transceiver strategy across high-speed access and aggregation layers.
