SFP-10/25G-CSR-S Description
SFP-10/25G-CSR-S is a Cisco dual-rate SFP28 optical transceiver supporting both 10Gbps and 25Gbps Ethernet. Designed for extended-reach, high-performance data center connections, it enables seamless upgrades and compatibility in mixed 10G/25G environments. This module operates over OM3/OM4 multimode fiber, delivering up to 300 meters (OM3) or 400 meters (OM4/OM5) with standard LC connectors. SFP-10/25G-CSR-S is hot-swappable, energy efficient (1.2W), and requires RS-FEC for 25G operation. Commonly known as Cisco 25G CSR SFP28 or 10/25G SFP28 CSR, it is ideal for modern leaf-spine architectures, inter-rack connections, and aggregation links in cloud, enterprise, and service provider networks.

Key Features
- Application:
- Designed for extended-reach 10G/25G Ethernet links within and between data center racks, large server rooms, or campus buildings.
- Excellent for leaf-spine, inter-rack, and cross-floor aggregation, especially where fiber runs exceed typical SR or SL distances.
- Functionality:
- Dual-rate (supports both 10G and 25G speeds) for flexible upgrade and mixed-network deployments.
- Longest multimode reach in SFP28 series (up to 300m on OM3, 400m on OM4/OM5).
- RS-FEC required on host for 25G operation; optional for 10G.
- Ideal for future-proofing large data centers, minimizing switch layers, and supporting scalable cloud architectures.
- Industries:
- Telecom, cloud providers, large enterprises, universities, research institutions.
Applications Scenarios
Extended-Range Data Center Links
Provides high-speed 10G or 25G connectivity between switches or server racks across long distances (up to 400m), minimizing network hops and reducing latency.
Mixed-Speed Upgrade Environments
Perfect for organizations transitioning from 10G to 25G networks, allowing flexible use in dual-rate deployments without hardware changes.
Campus, Enterprise & Cloud Aggregation
Used in large campuses, carrier data centers, and cloud platforms for aggregation, spine-leaf connections, and distribution layers requiring long multimode fiber runs.
