TP-Link TL-FC111PB-20 10/100Mbps WDM Media Converter with 1-Port PoE

Quick guide from the manual

The TP-Link TL-FC111PB-20 is a WDM Media Converter designed to extend Ethernet networks. It supports 10/100Mbps speeds and provides 1-Port PoE (Power over Ethernet) to connected devices. Before installation, ensure your PoE device does not require more than 15.4W of power, as this is the maximum output of the converter.

LED Explanation

Monitor the device status using the front panel LEDs:

• PWR: On indicates the device is powered on; Off indicates it is powered off.
• Link/Act: On indicates a valid link; Flashing indicates data is being transmitted or received; Off indicates an invalid link.
• PoE: On indicates the device is supplying power normally; Off indicates abnormal power supply or no power supply.

Connection Scenarios

The device supports two primary connection scenarios depending on your network equipment:

• Scenario 1: Connect Devices with Optical Interfaces: Connect your Ethernet device with an optical interface directly to the Media Converter using an LC-SC Fiber Cable. Connect the Media Converter to your Powered Device (e.g., PoE IP Camera or AP) using a Twisted-Pair Cable.
• Scenario 2: Connect Devices without Optical Interfaces: Use two Media Converters to bridge two Ethernet devices that lack optical interfaces. Connect each Ethernet device to a Media Converter via Twisted-Pair Cable, and connect the two Media Converters to each other using an SC-SC Fiber Cable.
