The TP-Link FC111A-20 is a Fast Ethernet media converter designed to extend network connections over single-mode fibre across long distances. Ideal for CCTV systems, remote sites, and building-to-building links, it provides a reliable way to connect copper Ethernet networks to fibre infrastructure.
Working as part of a WDM pair with the matching FC111B-20, the FC111A-20 enables bi-directional data transmission over a single fibre strand, helping to reduce cabling costs while maintaining stable network performance. Its long-range design supports fibre links of up to 20 km, making it well suited to remote deployments.
With a plug-and-play design, the FC111A-20 requires no configuration, allowing for quick and straightforward installation. Compact and durable, it offers a practical and cost-effective solution for extending network reach where traditional Ethernet cabling is not suitable.
