Deliver short-reach 40 GbE connectivity with a Cisco-compatible 40GBASE-SR4 QSFP+ module engineered for multimode fiber environments. This transceiver is a practical fit for data center fabrics, switch uplinks, and high-density aggregation layers where predictable interoperability and efficient port use matter. The QSFP+ form factor supports compact deployment across modern switching platforms, while the 40 Gbps data rate provides the bandwidth needed for east-west traffic and backbone links inside the rack or across adjacent rows. For teams balancing performance and procurement discipline, this module offers a straightforward path to production-ready optics without overbuying capacity or features. Use it where short-reach optical links need to be stable, repeatable, and easy to standardize. It helps reduce cable congestion, preserve switch ports, and keep critical infrastructure traffic on a clean 40 GbE path. For enterprise buyers, that combination of compatibility, density, and speed is what makes this module worth specifying.
