Repeaters are optional components on the FC bus that increase the maximum allowable length and device counts of the FC bus. One repeater is counted as one device on the FC bus. Repeaters are not allowed on the SA Bus. Table 1 describes how the length and device maximums of the bus change when you add repeaters. The repeater is specified in Local FC Bus rules and specifications.
A maximum of two repeaters can be between any two points on the FC bus.
- The values in this table represent the recommended 3 conductor, 22 AWG stranded, shielded cable.
- Some device models and third-party devices may have reduced capabilities.
