Add copper connectivity to SFP-based switches and media paths without replacing the host hardware. This AddOn Networks RJ-45 SFP module is designed for environments that need a direct Ethernet handoff over twisted-pair cabling, making it a practical choice for access-layer links, temporary expansions, and mixed-media networks. Its plug-in form factor keeps deployment simple: insert the module, connect the copper patch lead, and bring the port online. For teams standardizing on SFP slots but still supporting legacy copper runs, this module helps preserve port flexibility while avoiding unnecessary chassis changes. Because it is built for network infrastructure rather than consumer use, it suits procurement decisions where compatibility, port density, and operational simplicity matter. The compact design is especially useful in switch stacks, branch closets, and edge deployments where every port must earn its place. When the requirement is reliable copper connectivity through an SFP interface, this module provides a clean, purpose-built option.
