The TP-Link TL-FC111PB-20 optical media converter converts data signals between optical fibre and a metallic network. The device transforms an electrical signal from a classic twisted-pair cable into an optical signal and vice versa. This process extends the reach of an Ethernet network over long distances while maintaining data transmission stability. The converter supports IEEE 802.3, IEEE 802.3i and IEEE 802.3u network standards, ensuring broad compatibility with existing network infrastructure.


The device allows data transmission over a distance of up to 20km. It uses a single-mode 9/125μm optical fibre with an SC connector for interconnection. The TP-Link TL-FC111PB-20 media converter thus overcomes the 100-metre distance limit of conventional metallic cabling and is an optimal solution for connecting remote points in large areas. The connection is reliable and without loss of signal quality over the entire length of the route.

Integrated WDM technology allows both transmission and reception of data over a single optical fibre. The device transmits a signal at a wavelength of 1,310nm and receives at a wavelength of 1,550nm. Wavelength division multiplexing halves the cost of installing a cable route because it eliminates the need to lay a second optical fibre. For correct operation, an opposite device is required that transmits at a wavelength of 1,550nm and receives at 1,310nm.

The TP-Link TL-FC111PB-20 media converter has one Ethernet port with support for the 802.3af PoE standard. The port provides power for connected end devices such as network cameras or wireless access points. The power output simplifies the construction of camera systems in locations without available electrical sockets.

The RJ45 Ethernet port supports a transmission speed of 100Mb/s and the Auto MDI/MDI-X function for automatic detection of crossover cables. The device automatically negotiates half-duplex or full-duplex transmission mode. The system thus operates without the need for manual setting of network interface parameters. The device is equipped with PWR, Link/Act and PoE LED indicators for immediate status checks.

The design functions reliably in environments with temperatures from 0 to 50°C and at an operating humidity of 10–90% RH without condensation. The compact dimensions of 27×94.5×73mm allow for installation in confined spaces. The media converter works as a stand-alone unit or can be placed in a compatible TP-Link TL-FC1420 rack for centralised management of multiple units.
