Move 100 GbE traffic across multimode fiber with a QSFP28 transceiver built around the 100GBASE-SR4 standard. This AddOn Networks module is designed for environments that need high-density uplinks without redesigning the fiber plant, making it a practical choice for switch refreshes, aggregation layers, and top-of-rack connectivity. JL309A compatibility helps simplify replacement planning in HP-aligned infrastructures, while TAA compliance supports procurement requirements in regulated organizations. For teams balancing performance and sourcing discipline, this module offers a straightforward path to maintain link speed while staying within established vendor and compliance boundaries. SR4 optics are a familiar fit for short-reach multimode deployments where predictable interoperability and port efficiency matter. When the goal is to preserve 100 GbE performance without overbuying capability, this transceiver gives infrastructure teams a focused, enterprise-ready option.
