Extending the Interconnecting Medium or Backbone
The backbone side of the EXTEND-A-BUS must comply with
standard ARCNET cabling rules. Companion AI ARCNET
active hubs are available for extending the backbone cabling up
to 6 km using coaxial cabling and ten active hubs. When using
a fiber optic backbone, a maximum of 4.8 km can be achieved
requiring two active hubs. Hubs are cascaded to reach the
required distance.
