ISABEL is a centrally managed interface converter from fiber to copper (FTTD). LAN based on optical fiber allow direct connections up to 3 km. Since end devices can only handle Ethernet, ISABEL is the product of choice as a directional converter. In addition to Ethernet, Token Ring, V.24/V.28, SS 97 and IHSS are also supported.
As sales partners, ABB (Asea Brown Bovery) and Alcatel have placed around 58,000 devices in building technology under their own brand over several years.
