This AddOn compatible module supports 100BASE-FX operation over multimode fiber with an LC interface and a documented reach of up to 2 km, making it a strong fit for campus, plant, and distributed network segments. The hot-swappable form factor helps reduce maintenance windows, while TAA compliance supports procurement requirements in regulated and public-sector environments. For teams managing legacy optical infrastructure, this module offers a straightforward way to restore service without redesigning the link or paying for unnecessary feature sets. AddOn’s compatibility approach is aimed at infrastructure buyers who care about fit, serialization, and repeatable deployment outcomes. When the priority is restoring a port quickly and keeping the network on standard parts, this transceiver delivers the right balance of reach, compatibility, and sourcing control.
