Overview
Extend Your Network with the TP-Link TL-FC111PB-20 WDM Media Converter
The TP-Link TL-FC111PB-20 is a 10/100 Mbps WDM (Wavelength Division Multiplexing) media converter designed to extend your network over long distances using fiber optic cable. With PoE (Power over Ethernet) output, this converter offers both data and power transmission through a single cable, simplifying your network infrastructure.
Specifications:
- Interface: 1 x 10/100 Mbps RJ45 Port, 1 x 100Base-FX Single-Mode Fiber Port
- PoE Output: Yes
- Fiber Distance: Up to 20 km
- Wavelength: 1310 nm
- Data Rate: 10/100 Mbps
- Standard: WDM (Wavelength Division Multiplexing)
Key Features
Designed to convert 100BASE-FX SC fiber to 100Base-Tx copper media or vice versa
Auto-negotiation of Half-Duplex/Full-Duplex transfer mode. Supports auto MDI/MDIX for TX port
The 802.3af PoE output makes remote camera deployment easier and more convenient.
TL-FC111PB-20 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance up to 20 km with only one single-mode fiber, which saves half of the cable deployment cost for customers compares to dual-fiber deployment.

Pros & Cons
👍 Pros
- Efficiently converts 100BASE-FX SC fiber to 100Base-Tx copper media and vice versa, bridging different network types.
- Supports auto-negotiation for Half-Duplex/Full-Duplex transfer mode, simplifying network configuration.
- Features auto MDI/MDIX for the TX port, eliminating the need for crossover cables and simplifying setup.
- Incorporates 802.3af PoE output, making it easier and more convenient to deploy remote cameras without separate power sources.
- Utilizes WDM (wavelength division multiplexing) technology, allowing data transmission up to 20 km over a single-mode fiber.
- WDM technology significantly saves on cable deployment costs by reducing the need for dual-fiber setups.
- Designed for compatibility with TP-Link model TL-FC111A-20, ensuring a paired solution for fiber optic links.
👎 Cons
- The 10/100 Mbps speed is a Fast Ethernet standard, which may be a limitation for networks requiring Gigabit or faster speeds.
- The WDM technology requires a compatible counterpart (TL-FC111A-20) for a full connection, which is not included.
- The specified wavelength of Tx 1310 nm, Rx 1550nm means it's not universally compatible with all WDM devices without checking specifics.
- While it supports PoE, it is limited to the 802.3af standard, which might not be sufficient for higher power PoE+ or PoE++ devices.
- The maximum distance of 20 km, while substantial, might not meet the requirements for extremely long-distance fiber deployments.
- Only one fiber port is available, limiting its application in scenarios requiring multiple fiber connections from a single device.
