Cisco SFP-10G-SR 10GBASE-SR SFP Plus Transceiver Module

The Cisco SFP-10G-SR 10GBASE-SR SFP+ module is a fiber optic transceiver that delivers 10 Gbps Ethernet over short-range multimode fiber for compatible Cisco networking gear. It operates at 850 nm, uses an LC duplex connector, and is hot-swappable, fitting into standard SFP+ slots to provide reliable, high-bandwidth uplinks and interconnections in data centers and enterprise networks. This transceiver supports up to 300 m on OM3 multimode fiber, making it suitable for switch-to-switch uplinks, server connections, and data-center aggregation where quick, reliable 10G links over MMF are essential. Common replacements include Cisco SFP-10G-SR-S and Cisco SFP-10G-LR for extended reach, while Intel E10GSFPSR is another widely used 10GBASE-SR/LR option in similar deployments across enterprise and data-center networks. This module is designed for hot-swappable deployment in crowded data-center racks and enterprise edge closets, helping minimize downtime during upgrades and supporting scalable 10 Gigabit Ethernet connectivity across a growing network.
