With a built-in 802.3af PoE output port, it can power an IP camera or other PoE device directly at the remote end of the fibre link, eliminating the need for a separate power source at the camera location. Ideal for long-distance CCTV deployments, inter-building links, and remote surveillance installations across Australia.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The TL-FC111PB-20 (TX 1310nm \/ RX 1550nm) must be paired with a complementary \u003cstrong\u003eTL-FC111PA-20\u003c\/strong\u003e (TX 1550nm \/ RX 1310nm) at the opposite end of the fibre link.

Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat unit do I need at the other end of the fibre link?\u003c\/h3\u003e\n\u003cp\u003eThe TL-FC111PB-20 (TX 1310nm \/ RX 1550nm) must be paired with a \u003cstrong\u003eTL-FC111PA-20\u003c\/strong\u003e (TX 1550nm \/ RX 1310nm) at the opposite end. Using two TL-FC111PB-20 units on the same link will not work — the wavelengths must be complementary.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the PoE output power the remote camera or the local switch?\u003c\/h3\u003e\n\u003cp\u003eThe 802.3af PoE output is on the RJ45 port of the TL-FC111PB-20. This means the unit at the \u003cstrong\u003eremote end\u003c\/strong\u003e (near the camera) provides PoE power to the connected IP camera or device. The unit at the local end (near the switch) connects to a standard non-PoE switch port via copper Ethernet.\u003c\/p\u003e\n\n\u003ch3\u003eWhat fibre cable is required?\u003c\/h3\u003e\n\u003cp\u003eThe TL-FC111PB-20 requires 9\/125μm single-mode fibre with an SC simplex connector. It is not compatible with multi-mode fibre (OM1, OM2, OM3, OM4) or SC duplex patch leads. Ensure your fibre infrastructure is single-mode before purchasing.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use this to connect a camera more than 100m away without running power?\u003c\/h3\u003e\n\u003cp\u003eYes — this is the primary use case. Place the TL-FC111PA-20 at the switch end (connected to your NVR or switch via copper Ethernet), run a single-mode fibre strand to the camera location, and connect the TL-FC111PB-20 at the camera end. The TL-FC111PB-20 will power the camera via its PoE RJ45 port — no power outlet needed at the camera location.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the maximum PoE power output?\u003c\/h3\u003e\n\u003cp\u003eThe TL-FC111PB-20 provides 802.3af PoE output, which delivers up to 15.4W to the connected device. This is sufficient for most standard IP cameras and compact wireless access points. For devices requiring more than 15.4W (802.3at PoE+), a different solution is required.\u003c\/p\u003e\n\n\u003ch3\u003eIs this suitable for outdoor camera installations?\u003c\/h3\u003e\n\u003cp\u003eThe media converter itself is rated for indoor use (0–50°C) and should be installed in a weatherproof enclosure or indoor location. The connected IP camera can be outdoor-rated. For the fibre run, use outdoor-rated single-mode fibre cable appropriate for your installation environment.\u003c\/p\u003e","brand":"TP-Link","offers":[{"title":"Default Title","offer_id":43198328439013,"sku":"TL-FC111PB-20","price":58.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/1554\/1221\/files\/tl-fc111pb-20-tp-link-single-mode-fiber-converter.webp?v=1779689026","url":"https:\/\/cctvguru.com.au\/products\/tp-link-tl-fc111pb-20-wdm-media-converter-poe-20km","provider":"CCTV Guru","version":"1.0","type":"link"}
