Extreme Networks 10320 40G Ethernet QSFP+ LR4 Optical Module

Build longer 40 GbE runs without changing the network design around distance limits. This Extreme Networks QSFP+ LR4 optical module is built for single-mode fiber and supports links up to 10 km, giving teams a reliable option for campus backbones, data center interconnects, and other high-speed paths that span more than a single room. LR4 optics are a proven fit for environments that need more reach than short-range transceivers can provide while preserving the bandwidth required for storage, virtualization, and application traffic. The LC connector keeps fiber termination straightforward, and the QSFP+ form factor aligns with common 40 GbE deployment models. For infrastructure teams, the value is in precision: the right reach, the right connector, and the right speed for networks that still depend on 40 GbE. That makes this module a disciplined choice for extending capacity without overbuilding the link layer.
