Move high-speed traffic across short-reach fiber with the SonicWall 25GBaseSR SFP28 850 nm module. Built for 25 Gigabit Ethernet over multimode fiber, this transceiver gives infrastructure teams a compact way to add dense, high-bandwidth links without changing the physical footprint of the switch or appliance. The SR design is a practical choice for data center and campus environments where short optical runs are standard. At 850 nm, it aligns with common multimode cabling practices and supports clean integration into top-of-rack, leaf-spine, and aggregation architectures. That makes it useful when you need more throughput per port and a tighter rack design than 10 GbE can provide. For teams standardizing on SonicWall hardware, this module helps keep optical connectivity consistent and easy to scale. It is the kind of component that earns its place in higher-value deployments: compact, fast, and suited to environments where port density and link performance directly affect operational efficiency.
