Lenovo 00FE331 10GBASE-LR SFP+ Transceiver, 10 GbE | Optical Fiber

Keep long-reach Ethernet links stable across single-mode fiber with the Lenovo 00FE331 10GBASE-LR SFP+ transceiver. Built for optical networking and data networking applications, this module delivers 10 Gigabit Ethernet connectivity in a compact SFP+ form factor that fits standard switch and server ports. 10GBASE-LR is the right choice when you need dependable transport beyond the rack without moving to a more expensive optics tier. It is designed for single-mode fiber deployments and uses an LC connector, making it a practical fit for uplinks between switches, aggregation layers, and remote equipment rooms. For infrastructure teams, that means fewer compromises on reach, cleaner cabling, and a transceiver matched to long-distance 10 GbE links. Lenovo positions this module for environments where link stability and interoperability matter more than marketing claims. If you are standardizing optics across a Lenovo-based network, the 00FE331 gives you a straightforward path to extend 10 GbE with the reach and signal characteristics expected from LR optics. It is a focused component, not a general-purpose substitute, which is exactly why it belongs in production networks that need predictable performance.
