100GBASE-LR4 QSFP28 PROGRESS SOFTWARE 2-10 km

Deliver 100 GbE over longer single-mode runs with this QSFP28 LR4 transceiver from Progress Software. Built around LAN-WDM optics and LC connectivity, it supports 2-10 km reach, giving infrastructure teams the distance needed for campus backbones, data center interconnects, and aggregation layers that cannot rely on short-reach optics. The QSFP28 form factor keeps port density high while preserving a clean optical footprint in supported switches and network platforms. For teams standardizing on 100 GbE, LR4 is the right fit when the link must cross buildings, span a campus, or connect distributed network rooms without changing the fiber plant to a more complex architecture. This module is aimed at environments where link stability, reach, and interoperability matter more than simply hitting a headline speed. It helps justify the investment in 100 GbE by extending that bandwidth across real-world distances, reducing the need for intermediate gear and keeping the network design direct.
