Build short-reach 10 Gigabit links with a module designed for dense switching environments. Cisco SFP-10G-SR= delivers 10GBASE-SR performance over multimode fiber, making it a strong fit for top-of-rack switching, aggregation uplinks, and campus backbone segments that stay within short optical distances. Its SFP+ form factor helps maintain port density while keeping the optics footprint compact. The 850 nm wavelength aligns with common multimode fiber deployments, and LC connectivity supports standard enterprise cabling practices. For teams managing switch refreshes or expanding 10 GbE capacity, this module offers a clean path to higher throughput without changing the fiber plant where MMF is already installed. It is especially useful when you need consistent short-reach performance, straightforward interoperability, and a familiar operational model for spares and replacements. Choose this transceiver when the goal is to increase bandwidth without overbuilding the network. It gives infrastructure teams a practical way to connect servers, switches, and aggregation points with the optical characteristics expected in modern data center and campus designs.
