Preserve copper network access in SFP ports without changing the switch platform. This AddOn transceiver delivers 10/100/1,000Base-TX connectivity through an RJ-45 interface, making it a practical fit for access-layer uplinks, edge devices, and mixed-media environments where copper remains the right choice. TAA compliance supports public-sector and regulated procurement paths, while the IBM 00FE333 compatibility helps standardize replacement and expansion across installed infrastructure. For teams managing spares, refresh cycles, or vendor-aligned sourcing, this module reduces friction at the point of deployment. Use it where fiber is unnecessary, where copper runs are already terminated, or where you need a straightforward SFP-to-RJ-45 handoff for Gigabit Ethernet. AddOn’s form factor keeps the module aligned with standard SFP slots, so it drops into existing hardware without redesigning the network edge.
