Keep high-speed links stable across short-reach multimode runs with the Finisar FTL410QE4C 40GBASE-SR4 QSFP+ optical transceiver. Built for 40 GbE environments, it delivers MPO-based parallel optics for dense switching and aggregation layers where port efficiency matters. The SR4 design is well suited to data center fabrics that need predictable reach without moving to more expensive long-haul optics. At 850 nm and up to 150 m, this module fits the common multimode infrastructure used in enterprise and colocation deployments. The QSFP+ form factor supports compact, high-port-count switch designs, helping teams preserve rack space while maintaining throughput. For infrastructure groups standardizing on 40GBASE-SR4, it offers a straightforward path to expand bandwidth on existing multimode plant. Choose this transceiver when link consistency, density, and interoperability matter more than generic low-cost optics. It is a practical fit for teams refreshing uplinks, building leaf-spine topologies, or replacing aging 10 GbE connections with a cleaner 40 GbE layer.
