Keep 100 GbE traffic moving across short multimode links with this AddOn Networks QSFP28 SR4 transceiver. It is designed for data center environments that need high bandwidth in a compact optical footprint, supporting 100GBASE-SR4 operation at 850 nm with reach up to 100 m. The SR4 architecture is a strong fit for switch-to-switch and switch-to-server connectivity where multimode fiber is already in place. It helps maintain port density while avoiding the added cost and reach of longer-distance optics. For teams standardizing infrastructure, the QSFP28 form factor supports straightforward deployment in modern high-speed switching platforms. This module is especially relevant when procurement must balance performance, compatibility, and compliance. Its TAA-compliant status supports public-sector and regulated buying requirements, while the short-reach design keeps it aligned with the realities of dense data center layouts. For infrastructure teams, that means a cleaner fit for leaf-spine fabrics, aggregation layers, and rack-to-rack links where predictable optical behavior matters more than excess reach.
