Cisco SFP-10/25G-CSR-S Dual-Rate 10G/25G Transceiver Module

The Cisco SFP-10/25G-CSR-S is a high-performance, dual-rate Small Form-Factor Pluggable (SFP28) optical transceiver designed for next-generation data center and enterprise networks. It offers unique flexibility by supporting both 10 Gigabit Ethernet (10G) and 25 Gigabit Ethernet (25G) data rates over multimode fiber (MMF).

Part of Cisco’s S-Class portfolio, the "CSR" stands for Custom Short Reach, meaning it extends the transmission distance beyond standard SR (Short Reach) optics, making it a highly cost-effective solution for optimizing high-density fiber patches.

Key Features

Dual-Rate Capability: Supports seamless migration from 10G to 25G speeds on the same physical port without swapping the optical hardware.

Extended Short Reach (CSR): Optimized to transmit data further than standard SR optics over existing multimode fiber infrastructure.

Digital Optical Monitoring (DOM): Supports real-time monitoring of transceiver parameters such as optical output power, optical input power, temperature, and supply voltage.

Hot-Swappable: Plugs directly into any Cisco SFP28/SFP+ port without requiring a system reboot, ensuring uninterrupted network uptime.

S-Class Quality: Built specifically for mainstream enterprise and data center applications, offering Cisco's standard feature set at an optimized cost.

Transmission Distances

The maximum reach depends on the fiber type and the configured data rate:

At 25G Speed: Up to 300 meters over OM3 MMF, or 400 meters over OM4/OM5 MMF (with FEC).

At 10G Speed: Up to 300 meters over OM3 MMF, or 400 meters over OM4/OM5 MMF.

Applications

High-speed server-to-switch and switch-to-switch interconnects in data centers.
Future-proofing network infrastructure by deploying 25G-ready optics in 10G environments.
High-performance computing (HPC) networks requiring low latency and high bandwidth.
