Keep legacy fiber infrastructure online with a TAA-compliant 100BASE-FX SFP designed for Alcatel-Lucent environments. The AddOn 3HE00024CA-AO provides Fast Ethernet optics in a compact hot-pluggable form factor, giving network teams a straightforward replacement path when original OEM parts are unavailable or overpriced. Built for multimode fiber deployments, this transceiver uses an LC duplex connector and supports links up to 2 km, making it well suited for campus access, building interconnects, and short-reach uplinks. It is a practical choice when you need stable 100 Mb connectivity without changing the surrounding fiber plant. For procurement teams, the value is clear: OEM-compatible performance, TAA compliance for regulated purchasing, and a cost profile that supports spares stocking across multiple sites. For operations teams, it reduces downtime risk by keeping a known-good replacement on hand for aging switches and edge devices that still depend on 100BASE-FX optics.
