Build reliable 40 GbE connectivity into access, aggregation, and leaf-spine layers with a QSFP+ transceiver tuned for short-reach multimode operation. The Q7F11A-AO supports 40GBASE-SR4 signaling at 850 nm, making it a practical choice for data center links where bandwidth, port density, and predictable optical performance are essential. TAA compliance makes this module a strong fit for public sector and regulated procurement environments that require sourcing alignment without compromising network design. The QSFP+ form factor helps preserve switch density, while multimode fiber support keeps deployment straightforward in structured cabling environments already built around short optical runs. For teams refreshing legacy 10 GbE or standardizing 40 GbE uplinks, this transceiver offers a cost-conscious path to higher throughput with the optical characteristics expected in enterprise switching. It is well suited to rack-to-rack links, server aggregation, and switch interconnects where short reach is enough and reliability is non-negotiable.
