This 10/100 Base to 100 Base-FX (ST) Multimode Fiber Ethernet media converter supports a maximum fiber cable distance of 2km, ensuring a highly reliable signal for ideal network connectivity & performance. The fiber converter features Power over Ethernet support that allows the converter to draw power from a Po E network, delivering the freedom to use the converter in environments & scenarios where additional standard power options are unavailable. Rather than paying for expensive installations of power wire (at drop points that may have them), running Po E requires only standard network cable (e.g. Cat 5e cable), eliminating cost & hassle.
