    AI Overview
    The
    Allen-Bradley 1788-CN2FF is not a long-distance fiber repeater, but rather a ControlNet to FOUNDATION Fieldbus H1 linking device. It bridges ControlNet (copper) to Fieldbus H1 segments, supporting up to 16 devices without needing external power conditioners. It operates in DIN-rail mounted, IP20-rated enclosures. 
    Key Features and Capabilities 
    • Function: Bridges ControlNet communication to Foundation Fieldbus H1, allowing integration of field devices.
    • Media Support: Supports redundant media (1788-CN2FFR) for increased network reliability.
    • Power: Built-in power conditioning for the H1 segment, providing up to 500 mA per port.
    • Topologies: Supports star, ring, and point-to-point configurations.
    • Capacity: Manages up to 16 Fieldbus devices. 
    Actual Fiber Ring Repeaters (Alternative Product)
    If you are looking for long-distance, fiber-optic ring communication, the correct Allen-Bradley components are: 
    • 1786-RPFM (Multi-mode) / 1786-RPFS (Single-mode): Fiber repeater modules used to create ring or star topologies, expanding ControlNet distance using fiber optic cable. 
    For high-speed, long-distance, and secure communication, using the 1786 series fiber repeaters in a ring topology is the recommended solution.
