Flo-wire Ethernet converter, one single pair of cable can be used to distribute power and data. The cable hauls can be longer, up to 2 km, reducing the need for switches and/or repeaters. Up to 20 Flowire devices can be connected to the same 2-wire bus/star structure. Existing infrastructure can be used, even though only a single pair is available. This reduces the total cost of retrofit projects. The Flowire converter can be used with any Ethernet enabled device (not limited to STENTOFON products).
