Keep high-density F5 infrastructure moving with a 40GBASE-SR4 QSFP+ transceiver designed for short-reach multimode deployments. This module is built for 40 GbE uplinks where switch-to-switch or switch-to-server connectivity needs to stay compact, fast, and easy to scale. SR4 optics are a practical fit for data center fabrics that depend on parallel fiber signaling and tight rack-level cable runs. For teams standardizing on QSFP+ infrastructure, this transceiver helps preserve port density while supporting the throughput required by modern application delivery, virtualization, and east-west traffic patterns. Choose this module when you need a replacement or expansion optic that aligns with F5-compatible hardware and avoids unnecessary overbuying. It delivers the right reach and interface for multimode environments, making it a strong fit for controlled-distance deployments where performance and compatibility are non-negotiable.
