FC311B-20
Description
Gigabit WDM Media Converter - TP-Link TL-FC311B-20
🌐 Turn a single single-mode fibre optic into a reliable Gigabit connection over distances up to 20 km
🔌 Essential functionality
The TL-FC311B-20 is a wavelength division multiplexing (WDM) media converter that converts the signal between the RJ45 Gigabit port and a single-mode SC optical fibre, using a single fibre for long-distance bidirectional transmission(tp-link.com).
💡 Technology and compatibility
-
Transmits at 1310 nm and receives at 1550 nm; must be paired with TL-FC311A-20 (which works in reverse) to form a full link(tp-link.com)
-
Connects Ethernet devices (routers, switches, APs) to the optical network, ideal for remote surveillance or monitoring sites
