Catalog Numbers 1786-RPFRL/B, 1786-RPFRXL/B 

About the Module

The ControlNet Fiber-optic Ring Repeater module supports fiber media 
redundancy by using a ring topology. The fiber-optic technology permits long 
(1786-RPFRL/B module) or very long (1786-RPFRXL/B module) 
transmission ranges. Both modules provide optimum protection against EMI 
effects along the transmission link and at the repeaters themselves. The fiber link 
provides ground isolation between nodes and is less susceptible to noisy 
environments than traditional copper media.
