[shortdesc] SFP+ transceiver module 10 GigE 10GBase-SR LC/PC multi-mode Up to 1310 ft 850 nm [/shortdesc] Overview of the Cisco SFP-10G-SR (Short Reach) Transceiver The Cisco SFP-10G-SR is the industry-standard SR (Short Reach) transceiver, delivering reliable and cost-effective 10 Gigabit Ethernet connectivity over multi-mode fiber (MMF). It is the definitive choice for high-density connections within a data center, enterprise wiring closet, or a single building. Operating at 850 nm, this module supports link lengths up to 300 meters on OM3 and 400 meters on OM4 MMF. For longer-distance campus links between buildings (up to 10km), the SFP-10G-LR (Long Reach) version should be used with single-mode fiber. As a genuine Cisco SFP+ module, it supports Digital Optical Monitoring (DOM) for real-time diagnostics and features a low-power design ideal for high-density environments. Fully IEEE 802.3ae and SFP+ MSA compliant, the SFP-10G-SR ensures plug-and-play compatibility with a wide range of Cisco platforms. Technical Features Speed: 10 Gb/s (10GBASE-SR) Reach: Up to 300 m on OM3 | 400 m on OM4 multimode fiber Optics: 850 nm VCSEL laser, LC duplex interface Diagnostics: DOM support (Tx/Rx power, temperature, voltage) Power Consumption: ≤ 1 W (low power, ideal for dense deployments) Hot-Swappable: Yes — insert/remove without service interruption Operating Temperature: 0 °C to 70 °C (commercial grade) Compliance: IEEE 802.3ae, SFP+ MSA, Class 1 laser Ideal For: Data center links, Cisco switch uplinks, SAN/NAS over MMF
