Support high-throughput short-reach connections with a 40GBASE-SR4 QSFP+ transceiver built for multimode fiber networks. The AddOn Networks QSF-502-AO gives infrastructure teams a TAA-compliant alternative for Gigamon-compatible environments, helping maintain procurement flexibility without sacrificing deployment fit. Its QSFP+ design is well suited to dense ports, fast replacement cycles, and the operational demands of modern data centers. This module is intended for 40 GbE links where short-distance optical performance is the priority. SR4 optics are commonly used between adjacent racks, within aggregation tiers, and across leaf-spine fabrics where multimode cabling is already in place. That makes it a practical choice for teams standardizing on short-reach optics while keeping cable plant complexity low. For organizations that need verified compatibility and controlled sourcing, this transceiver offers a straightforward path. It supports the kind of infrastructure decisions that matter at scale: predictable interoperability, efficient spares management, and a cost profile that makes sense for multi-port deployments.
