Connectivity Guidelines
When adding hubs (repeaters) to your network, please follow the con- nectivity rules listed below for Fast Ethernet. However, note that because switches break up the path for connected devices into sepa- rate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
Maximum Fast Ethernet Network Diameter
Repeater Type | Twisted Pair | Twisted Pair/Fiber | ||
and Number | ||||
1 | Class I | 200m | (656 ft) | 260.8 m (855.4 ft) |
1 | Class II | 200m | (656 ft.) | 308.8 m (1012.6 ft) |
2 Class II | 205m (672.4 ft) | 216.2m (709.1 ft) | ||
Note: Network diameter is defined as the wire distance between the two end stations in the same collision domain.
