The TP-Link TL-FC311A-2 is a Gigabit WDM media converter designed to bridge the gap between electrical RJ45 and optical SC fiber signals. By utilizing a single-strand fiber, it allows you to extend your network reach up to 2 km, making it a practical choice for connecting distant devices without needing to install extensive new cabling. This device is housed in a durable grey metal casing that helps with heat dissipation and protects the internal components. It features a Gigabit RJ45 port and a Gigabit SC fiber port, ensuring high-speed data transfer that meets several IEEE standards, including 802.3ab and 802.3z. To help you monitor the connection at a glance, the front panel includes LED indicators for power and link activity. The unit operates on a 5V DC power supply, providing a stable and compact solution for network administrators who need to integrate fiber optics into an existing Ethernet infrastructure.
