    Overview

    • Converts an Ethernet connection into fiber for distances up to 80 kilometers
    • 1 x 100/1000BASE-T port
    • 1 x SFP port for long distance connections
    • No need to configure, simply connect and it is ready to go
    • High redundancy features such as Dual Power Input provides industrial-grade reliability
    • Resistant to temperatures between -40 and 70°C
    • IP30-rated ingress protection provides defense against small objects entering the device
    • Compact size allows for convenient installation, even in tight spaces

    D-Link’s Gigabit Industrial Unmanaged Media Converter turns an Ethernet connection into
    fiber, allowing for ultra-fast long distance connections. The DIS-M100G-SW media converter is
    housed in a highly resistant IP30-rated metal casing to protect the media converter from harsh
    environmental conditions. Meanwhile, the fanless design extends the life of the DIS-M100G-SW
    while also being able to operate in a wide temperature range from -40°C up to 70 °C. For
    increased flexibility, the DIS-M100G-SW can also be mounted on a DIN rail or conveniently
    mounted on a solid surface wall. In addition, the DIS-M100G-SW supports dual power input
    which allows for a redundant power supply configuration to make sure the media converter
    continues to operate in the event of a primary power supply failure.

    Extend Your Network
    Fiber-optic speeds are critical to success, but twisted-pair cabling can only go so far. Using
    D-Link’s converters you can change a twisted-pair Ethernet connection into a single-mode or
    multi-mode fiber connection that can go much further. Converters for distances of anywhere
    from 550 m to 80 km allow you to optimize your selection.

    No Wasted Space
    Its compact size fits anywhere and doesn’t require an entire rack. Measuring just 70 mm wide by 95 mm long by 26.1 mm in depth, with the total volume of one unit just 0.174 liters. This allows for convenient installation wherever it is needed, especially in limited space environments such as telecommunication cabinets or a distribution box.

    Plug and Play
    The media converters offered by D-Link include several industry-standard technologies that
    make them easy to operate, like 802.3u/x/ab. Auto-MDI/MDIX and Auto-Negotiation makes
    sure that your cable connection functions at the highest possible speed while remaining
    compatible. There’s no management software to configure – just simply connect the converter.
