Planning and Designing RIO Cable System

Connecting More
than Five Drops
The accompanying illustration shows how six RIO drops may be interconnected
using fiber optic cable but still remain within the maximum allowable limit of five
repeaters. Installers are cautioned against using ring configurations involving more
than five RIO repeaters. In the event of a break in the fiber cable, a linear
configuration will be the result and communication errors could occur if too many
repeaters are connected together. In the following illustration, dotted lines show
three and four RIO repeater ring configurations.
