Authorized North America Distributor StampThe ProfiHub B4FOR+ is a PROFIBUS DP RS485 copper cable to Fiber Optic Link module that can be used to create Multi-Mode or Single-Mode Fiber Optic Rings for PROFIBUS networks. Single-Mode allows for 50km fiber optic cable lengths, while Multi-Mode allows for 5km cable lengths. Status of the rings can be remotely monitored via ComBricks.

At the same time, this module supports RS485 cable redundancy for 2 cables and provides 4 copper segments. These PROFIBUS segments can be used with other ProfiHubs or ComBricks to create redundant copper cable runs on 2 cables between the hubs. If 2 copper cables are used for redundancy, then the remaining 2 segments can be used for PROFIBUS DP field devices.
