PROGRESS WUG-ACC-HW-40G-QSFP-LR4 40G QSFP+

Keep long-reach 40 Gigabit Ethernet links stable with a QSFP+ LR4 optic built for single-mode fiber. This module supports CWDM transmission and a 2 to 10 km reach, giving infrastructure teams a clean option for aggregation, backbone, and inter-building connectivity where multimode optics fall short. The LR4 design is a strong fit when you need predictable 40G performance over distance without moving to a larger or more complex transport layer. It preserves the compact QSFP+ footprint while delivering the reach required for campus networks, data center edge connections, and distribution uplinks. For teams maintaining mixed-generation infrastructure, this optic offers a straightforward path to extend 40G service across existing single-mode plant. It is the kind of component that earns its place by solving a specific problem well: carrying 40G traffic farther, with fewer compromises in port density and cabling strategy.
