SFP-25G-SR-S Description
SFP-25G-SR-S is a high-performance 25GBASE-SR SFP28 optical transceiver module designed for short-range data center and high-performance networking applications. This Cisco SFP28 SR transceiver supports 25Gbps Ethernet over multimode fiber (MMF), reaching distances of up to 70 meters on OM3 and 100 meters on OM4 cabling. Featuring a standard LC duplex connector, 850 nm wavelength, and hot-swappable SFP28 form factor, SFP-25G-SR-S ensures seamless integration with Cisco switches and routers. The module is also commonly referred to as Cisco 25G SR SFP28, SFP-25G-SR, or 25GBASE-SR SFP28. It is compliant with IEEE 802.3by, offers low power consumption, and requires RS-FEC on the host port for optimal operation.

Key Features
- Primary Application:
- Designed for high-speed, short-range 25Gbps Ethernet connections in modern data centers.
- Perfect for Top-of-Rack (ToR) or End-of-Row (EoR) switch-to-server links, where cable runs are typically under 100 meters.
- Environment:
- Best used with OM3/OM4 multimode fiber (MMF), ensuring maximum reach of 70m (OM3) or 100m (OM4/OM5).
- Functionality Highlights:
- Single-rate 25G operation; does not support 10G fallback.
- Requires RS-FEC on the host port for error-free performance.
- Hot-swappable SFP28 interface for minimal downtime.
- Low power consumption (1.2W), ideal for high-density deployments.
Applications Scenarios
High-Density Data Centers
Ideal for short-range 25G server-to-switch or switch-to-switch connections in modern, high-performance data centers.
Enterprise Campus Networks
Used for upgrading aggregation and core backbone links from 10G to 25G, supporting increased bandwidth demands.
Cloud and Virtualization Environments
Enables fast, reliable, and scalable fiber connectivity for virtualization, cloud computing, and high-throughput workloads.
