TP-Link TL-FC311B-20 Single-Mode SC Gigabit WDM Media Converter

The TP-Link TL-FC311B-20 is a single-mode SC Gigabit WDM media converter designed for bi-directional data transmission over a single fiber strand. It supports Gigabit Ethernet speeds (10/100/1000 Mbps) and extends network connectivity up to 20 kilometers, making it suitable for long-distance point-to-point connections between remote offices, campuses, or industrial sites.

Utilizing Wavelength Division Multiplexing (WDM) technology, this converter transmits data simultaneously in both directions using separate wavelengths (1310 nm Tx, 1550 nm Rx), reducing the need for multiple fiber cables. The device features a compact metal casing for durability, a 1× Gigabit SC port and 1× Gigabit RJ45 port with Auto MDI/MDIX, and is plug-and-play for easy installation.

Compliant with CE and FCC standards, the TL-FC311B-20 operates within a temperature range of 0°C to 50°C and is powered by a 5V DC, 1A supply. It is compatible with the TL-FC1420 rack-mountable chassis for centralized deployment.
