AddOn R5Z84A-AO 200GBASE-FR4 QSFP56 Transceiver

Keep high-speed backbone links moving with a 200GBASE-FR4 QSFP56 transceiver designed for single-mode fiber deployments. This AddOn Networks optic is compatible with the HP R5Z84A class and built for TAA-compliant environments where sourcing, standardization, and procurement controls matter. With LC duplex connectivity and a 2 km reach, it fits cleanly into data center uplinks, switch interconnects, and aggregation layers that need more bandwidth without changing the fiber plant. FR4 optics are a strong fit when you need 200 GbE performance over existing SMF infrastructure and want to avoid the cost and disruption of a full cabling refresh. The QSFP56 form factor supports compact, high-density switch designs, while the single-mode optical path helps preserve reach across campus or facility spans. For teams comparing lower-cost optics, this model stands out by aligning compatibility, compliance, and deployment practicality in one part number. Use it where link reliability, procurement discipline, and port density all matter. It is a straightforward choice for infrastructure teams standardizing on 200G uplinks and looking for a compatible replacement or expansion optic that fits enterprise purchasing requirements.
