Backbone Link Guidelines
In a backbone network, a single continuous cable connects all devices served by the link. The unbroken cable allows
you to install a permanent network that maintains a high level of reliability, even when you must attach, disconnect, or
move a device.
Use the backbone topology for large and permanent networks; it is also a good solution when connecting a few devices
located in the same general area.

1. Locate the CCM anywhere along the backbone.
2. Terminate devices at both ends of each backbone link. Leave all others unterminated.
3. Attach up to 32 devices on each link.
4. Limit combined cable length (from CCM to farthest device) up to 1 km (3281’) or less.
5. To attach unterminated devices, strip 1.2 cm (.5”) of insulation from each conductor at the connection point, fold in
the middle of the stripped area, and secure in the device’s compression connector.
