When the job calls for copper handoff instead of fiber, this AddOn RJ-45 SFP keeps the deployment simple. It delivers Gigabit Ethernet over 10/100/1000Base-TX connections in a hot-swappable SFP format, making it a straightforward fit for access switches, mixed-media networks, and replacement inventories. The 10-pack packaging is useful for teams standardizing spares across multiple closets or rolling out copper uplinks in volume. MSA compliance supports interoperability in compatible platforms, while the RJ-45 interface avoids the need for separate media converters in many environments. For procurement teams, the pack format can reduce per-unit handling overhead and simplify stocking. This module is a practical choice when you need dependable copper connectivity in a compact transceiver form factor. It is backed by a lifetime warranty, adding confidence for long-term operations and refresh cycles.
