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

TL-FC111PB-20 is a 10/100 Mbps WDM media converter with an integrated 802.3af PoE output. It provides one 10/100 Mbps PoE RJ45 port and one 100 Mbps SC fiber port, converting electrical Ethernet signals to optical signals for long-distance transmission. The converter supports single-mode fiber transmission up to 20 km using WDM technology, enabling distance extension of an existing network while reducing cable deployment cost. The device transmits on 1310 nm and receives on 1550 nm and can operate standalone or mounted in TP-Link's TL-FC1420 rack.

Advantages

The media converter integrates PoE power delivery with fiber conversion, allowing both data and power to be delivered over the RJ45 port to compatible powered devices. WDM operation permits bidirectional communication over a single single-mode fiber, lowering fiber usage and installation cost. The unit supports automatic MDI/MDI-X on the TX port and can function as a standalone device or in a TL-FC1420 rack.

Suitable for

• Extending Ethernet networks over long distances between buildings or sites
• Powering and connecting remote cameras, access points or other PoE devices via fiber
• Integrating fiber links into existing 10/100 Mbps copper networks
• Small deployments requiring a single-port media conversion with PoE

Key specifications

• Data rate: 10/100 Mbps
• Ports: 1× 10/100 Mbps PoE RJ45, 1× 100 Mbps SC fiber
• Fiber type: single-mode (9/125 µm), WDM
• Optical wavelengths: transmit 1310 nm, receive 1550 nm
• Maximum fiber transmission distance: up to 20 km
• Power input: 48 V, 0.5 A
• PoE standard: 802.3af

How to use

Install the TL-FC111PB-20 near a power source and connect the SC single-mode fiber to the fiber port. Ensure the opposite-end media converter or transceiver uses the complementary wavelengths (opposite transmit/receive wavelengths). Connect the RJ45 PoE port to a PoE-capable device such as an IP camera or access point. The device negotiates duplex and MDI/MDI-X automatically; no configuration is required for basic operation. The converter can be placed on a shelf as a standalone unit or mounted in the TL-FC1420 rack.

Recommendations

Use single-mode 9/125 µm fiber and verify that the remote transceiver matches the TL-FC111PB-20 wavelength pair (transmit 1310 nm / receive 1550 nm). For reliable PoE power delivery, confirm that the powered device is compatible with 802.3af and that the power budget meets the device's requirements.
