    TP-Link TL-FC111A-20 Media Converter

    Able to convert electronic signals to light signals and vice versa, this media converter is designed to connect twisted pair cable to a fiber-optic cable, allowing interconnection of fiber-based network and conventional copper-based network. It can be used to insert a fiber segment into a copper network to increase cabling distance and enhance cabling immunity to EMI. The support for auto-negotiation of half-duplex/full-duplex simplifies setup.

    The TL-FC111A-20 can work with TL-FC111B-20 in pair.

    What This Product Does

    TL-FC111A-20 is a 100M media converter, providing a 100M RJ-45 port and a 100M SC fiber port, which can convert between electrical and optical signals. And long-distance data transmission through optical fiber can be applied to commercial scenarios such as park security monitoring and wireless networking.

    How This Product Works

    TL-FC111A-20 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 20 km with only a single mode fiber, which saves half of the cable deployment cost for customers. TL-FC111A-20 transmits data at 1550nm wavelength and receives data at 1310nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the TL-FC111A-20 should send data at a wavelength of 1310nm and receive data at a wavelength of 1550nm. TP-Link another media converter TL-FC111B-20 is one of the products that can cooperate with TL-FC111A-20.

    Other Features

    Besides, this media converter can be used as a standalone device (no rack required) or used with TP-Link’s TL-FC1420 rack for auto MDI/MDI-X in TX port in which duplex mode is automatically negotiated.
