ProfiHub B2FO2+ PROFIBUS Fiber Optic Coupler The ProfiHub B2FO2+ is an economic solution to convert PROFIBUS fiber optic to RS 485 copper segments and vice versa. The ProfiHub B2FO2+ is designed to be a part of the communication backbone of your fiber optic PROFIBUS DP network. The increased functionality of spur lines, and isolated segments create a network component which reduces all of the costs associated with the most common network communication issues. The ProfiHub B2FO2+ is designed with the unique functionality of two galvanic isolated transparent repeaters and an optical link module in one device. It supports multiple fiber optic topologies; point-to point, bus and star. The B2FO2+ allows network structures with two extended spur lines that individually can handle a maximum of 31 devices and a length equal to the main bus. Both copper segments have DP - RS 485 specifications. Because the B2FO2+ creates isolated segments, the devices can be removed and added during operation. Also electrical bus problems and EMC disturbances in a spur do not spread to the other segments. The intelligent logic and isolation circuits of the ProfiHubs do not change the bit width. This means the ProfiHubs do not have limitations in serial placement.
