Keep critical 40 GbE paths active with this Axiom 40GBASE-SR4 QSFP+ transceiver for NetApp deployments. It is intended for multimode fiber and short-reach optical links, making it a practical choice for data center fabrics, storage interconnects, and aggregation layers that need stable throughput without unnecessary reach. SR4 optics are well suited to parallel short-distance connections, especially where port density and consistent performance are more important than long-haul transport. For teams maintaining existing 40 GbE infrastructure, this module supports a straightforward replacement or expansion path that aligns with established QSFP+ architectures. The value is in matching the right optic to the job: 40 GbE, multimode fiber, and a form factor designed for high-density environments. That keeps procurement focused, avoids overspecifying the link, and helps preserve budget for the parts of the stack that need it most.
