## Summary description

The TP-Link TL-FC111B-20 is a 10/100 Mbps WDM Media Converter that supports a maximum data transfer rate of 100 Mbit/s. It adheres to IEEE networking standards and features a single-mode fiber optic connector (SC) with a maximum transfer distance of 20,000 meters. This wired connectivity solution is ideal for extending your network over long distances, ensuring reliable performance with LED indicators for activity, link, and power. Compact and efficient, it operates on 5V output voltage and 0.6A current, making it a versatile choice for various networking needs.

## Long description

The TL-FC111B-20 is a 100M media converter that provides one 100M RJ-45 Ethernet port and one 100M SC fiber port to convert electrical signals to optical signals and vice versa. It enables long-distance data transmission over fiber for applications such as campus or park security monitoring and wireless network backhaul.
Advantages
Using WDM (wavelength division multiplexing) technology, the TL-FC111B-20 transmits and receives data over a single fiber, reducing fiber cabling requirements. It supports up to 20 km (12.4 miles) transmission distance, uses 1310 nm for transmission and 1550 nm for reception, and can operate standalone or mounted in TP-Link racks for centralized installation and automatic MDI/MDI-X negotiation.
Key specifications
Data rate: 100 Mbps
Electrical port: 1 × RJ-45 (100M)
Optical port: 1 × SC (100M)
WDM wavelengths: TX 1310 nm, RX 1550 nm
Maximum fiber distance: 20 km (12.4 miles)
Operation mode: Standalone or rack-mount (compatible with TL-FC1420 rack)
How to use
Connect the Ethernet device to the RJ-45 100M port and connect the fiber cable to the SC port. Ensure the device at the remote end is the complementary model (TL-FC111A-20) that transmits at 1550 nm and receives at 1310 nm. Power on the unit; duplex and MDI/MDI-X negotiation occur automatically when used in a compatible rack or with standard Ethernet devices.
Recommendations
For optimal performance, use single-mode fiber of appropriate quality, verify that the remote unit is the matching pair (TL-FC111A-20), and consider using the TL-FC1420 rack for centralized power and automatic MDI/MDI-X when deploying multiple converters.
