Cable Length and Lobe Wiring Rules for Dedicated-Media
Token-Ring Segments
The Olicom Token-Ring network dedicated-media (full-duplex) connections
support only one attached entity (workstation or switch) per connection.
In a Token-Ring network, the section of cable that attaches a device to an access
unit is called a lobe.
The tables in this section specify the maximum supported lobe lengths for the types
of cables listed below. An additional 10 m (33 ft) per lobe length is allowed to
accommodate patch cables, unless otherwise specified.
