QLOGIC 10GB SFP+ SR Optical Transceiver Lenovo 49Y4218 | SFP+ Module

Maintain high-speed connectivity where short-reach fiber links need predictable performance. The QLogic 10GB SFP+ SR Optical Transceiver is designed for 10 Gigabit Ethernet environments that depend on multimode fiber and compact, hot-pluggable optics. With 850 nm short-reach signaling and an LC duplex connector, it fits cleanly into switch-to-server, switch-to-storage, and aggregation-layer deployments where port density matters. This module is a practical choice for teams standardizing on SFP+ infrastructure and looking to preserve compatibility across enterprise switching platforms. Its SR design is well suited to data center rows, wiring closets, and other controlled environments where multimode fiber runs are kept within short distances. The compact form factor supports efficient port utilization without adding unnecessary complexity to the network edge. For infrastructure teams, the value is in consistency: a purpose-built transceiver that supports 10 GbE links with the optical characteristics expected in enterprise multimode deployments. When uptime, cable discipline, and predictable link behavior matter, this module helps keep the network layer aligned with the rest of the hardware stack.
