Planning a DH II Cable System

ATTENTION: Do not bend the trunkline cable so that it has a
bend-radius of less than 6 inches (15.2 cm). Bending the cable more
than the recommended bend-radius may decrease the reliability of
the network.

You should plan your dropline cable routing so that the bend-radius for the
dropline cable is not less than 3 inches (7.6 cm).

ATTENTION: Do not bend the dropline cable so that it has a
bend-radius of less than 3 inches (7.6 cm). Bending the cable more
than the recommended bend-radius may decrease the reliability of
the network.

Selecting the shortest path for routing the cable helps minimize the amount of
cable you need. The specific details of planning such a cable route depends
upon the needs of your network.

ATTENTION: When determining cable lengths, do not allow
tension to be exerted on the cable. Tension on the cable can damage
the cable and connectors. To minimize tension, allow sufficient slack
in the cable.
