5 meters = 16 feet, 100 meters = 328 feet,
200 meters = 656 feet, 205 meters = 672 feet
Hub-to-Workstation
Distance
100 meters maximum using twisted-pair cable
Inter-hub Distance 10 Mbps link: 100 meters using twisted-pair cable
100 Mbps link: 5 meters using twisted-pair cable (assumes
100 meters from each node to the hub)
Total Network Span
Single Hub
200 meters of twisted-pair cable
(100 meters to each attached node)
Two-hub Chain
1
205 meters of twisted-pair cable
(100 meters to each attached node, and 5 meters between
hubs)
1. When cascading a dual-speed hub to another dual-speed hub or to a 100 Mbps hub, the cascade is
limited to two hubs, and the interhub cabling is limited to 5 meters. However, up to three 10 Mbps
hubs can be cascaded off of a dual-speed hub using 100 meters of cable for each link.
