Keep 100 GbE links stable across campus backbones, aggregation layers, and data center interconnects with this QSFP28 LR4 compatible transceiver from AddOn Networks. Designed for long-reach single-mode deployments, it gives infrastructure teams a practical way to preserve port density while extending fiber runs without changing the switching platform. The LR4 optical design is a strong fit for environments that need predictable reach and clean interoperability across mixed vendor networks. LC duplex connectivity keeps cabling straightforward, while the QSFP28 form factor supports compact, high-bandwidth deployments in switches and routers built for 100 GbE uplinks. For teams standardizing on higher-speed optics, this module helps avoid the cost and complexity of overbuilding short-reach links or adding unnecessary intermediate gear. It is a straightforward choice when the requirement is simple: move 100 GbE farther, with fewer compromises and less rack space consumed.
