Lenovo 46C3449 10G-SR SFP+ Transceiver Module | 10 GbE, LC, Enterprise

Maintain clean 10 GbE connectivity across short-reach multimode fiber with the Lenovo 46C3449 10G-SR SFP+ transceiver module. Designed for enterprise switching environments, it delivers 850 nm short-reach optics through an LC interface, making it a practical fit for top-of-rack uplinks, server aggregation, and dense campus wiring closets. This module is built for teams that need consistent link performance without overbuying distance they will never use. The 10 GbE data rate supports modern access and aggregation layers, while the SR optical profile keeps the deployment focused on cost-efficient multimode infrastructure. That combination makes it a strong choice for environments standardizing on short fiber runs between switches, servers, and storage platforms. For infrastructure teams, the value is in fit and predictability: a known Lenovo sourcing path, a widely deployed SFP+ form factor, and optics tuned for the distances most data center racks actually require. When the goal is to preserve bandwidth, simplify spares, and avoid unnecessary transceiver spend, this module belongs in the bill of materials.
