Questions & Answers
What is the TL-FC111A-20 fiber media converter?
The TL-FC111A-20 is a bi-directional WDM media converter that converts 10/100 Mbps RJ45 copper Ethernet to 100 Mbps single-mode fiber via an SC connector, enabling cost-effective fiber runs over existing single fiber.
Which data rates does the TL-FC111A-20 support?
This converter supports 10 Mbps and 100 Mbps Ethernet on the RJ45 port and 100 Mbps full-duplex transmission on the single-mode fiber port.
What fiber connector type does the TL-FC111A-20 use?
It uses a standard SC simplex connector on the single-mode fiber port for easy installation and compatibility with most fiber infrastructures.
How far can the TL-FC111A-20 transmit over single-mode fiber?
Over single-mode fiber, the TL-FC111A-20 supports link distances up to 20 km (12.4 miles) using standard ITU-T G.652 compliant fiber.
What does WDM bi-directional mean on the TL-FC111A-20?
Wavelength Division Multiplexing (WDM) bi-directional technology allows simultaneous send and receive over a single fiber strand by using two different wavelengths—1310 nm Tx and 1550 nm Rx.
Is the TL-FC111A-20 hot-swappable?
Yes. The fiber module is hot-swappable: you can insert or remove the media converter without powering down your network equipment.
Which devices are compatible with the TL-FC111A-20?
