    The Transition Networks E100BTXFX06SMLCNA is a stand-alone Fast Ethernet media converter that connects 100Base-TX copper Ethernet to 100Base-FX fiber, making it suitable for network teams extending or integrating 100 Mbps fiber links into copper networks.

    Recommended For

    • Network installers extending an existing 100Base-TX connection beyond copper Ethernet’s 100 m limit over single-mode LC fiber, such as between buildings; this SMLC model is specified for links up to 20 km.
    • IT teams connecting a 100Base-TX device to equipment that already has a compatible 100Base-FX fiber port; the converter can be used as a single unit rather than only in a pair.
    • Facilities or network teams building a copper-to-fiber-to-copper Fast Ethernet link between two locations, using a matching converter at each end and compatible single-mode LC fiber.
    • Operators maintaining legacy 100 Mbps Ethernet equipment who need a simple physical-layer conversion; the Layer 1 design passes traffic at line speed without store-and-forward delay.
