About the SFP-10G-SR
The Cisco SFP-10G-SR is a widely deployed 10GBASE-SR optical transceiver designed for enterprise data networks and storage area fabrics. Operating at 850nm over multimode fibre, it achieves transmission distances up to 300 meters on OM3 cabling and up to 400 meters on OM4 cabling. It delivers consistent low-latency packet forwarding for virtualization hosts and NAS storage appliances.
Compatibility
Universally supported across Cisco Nexus 9000, Nexus 5000, and Catalyst switches, including Nexus 93180YC-FX and 93180YC-FX3 dual-speed ports. It links reliably with PCIe 10GbE server adapters, NAS controllers, and hyperconverged infrastructure appliances across all standard enterprise environments.
How to identify a genuine unit
Features a rugged SFP+ body with a beige bail clasp handle and Cisco holographic security sticker. The manufacturer label displays Cisco part number SFP-10G-SR, serial number, and safety certifications. In Cisco NX-OS and IOS-XE, the transceiver authenticates cleanly and supports complete digital optical monitoring.
Buying used
When purchasing used 10G optics, inspect the gold contact pins for signs of corrosion or physical scratching. Use a fibre optic inspection scope to verify that the internal transmitter and receiver ferrules are clean. Verify in switch telemetry that the transceiver reports stable operating temperatures and optical transmit levels.

Works together
How the Cisco SFP-10G-SR connects to servers, storage and the network: 3 ways, with the hardware on each path.
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.
