Move Gigabit Ethernet over the copper plant you already trust. The Aruba 1GBASE-T SFP 100 m Cat5e T module provides an RJ45-based SFP option for short-reach network links, supporting up to 100 m on Cat5e. It is a clean fit for access-layer switching, branch office uplinks, and mixed-media environments where copper remains the most efficient transport. This module gives you the flexibility of an SFP slot with the familiarity of twisted-pair cabling. That matters when you need to preserve switch port options while avoiding unnecessary fiber patching, optics selection, or transceiver sprawl. For teams standardizing on Aruba infrastructure, it offers a direct way to extend Gigabit connectivity using existing copper runs. Choose this module when the network design calls for dependable 1 GbE performance, short-reach deployment, and simple integration with RJ45 infrastructure. It is a practical, cost-aware answer for sites that need copper uplinks without compromising on switch-side modularity.
