Refer to Figure 51. Route the cable between the site locations of the
node devices. Guidelines for cable routing are described below. For
dual-cable routing, follow these guidelines for each cable.
V Use a continuous length of trunk cable between locations. Do not
use any splices.
V In dual-cable installations, make sure that each trunk cable, tap,
and drop cable is properly marked so that it can be positively
identified as belonging to Cable A or Cable B over the entire
end-to-end length of the network.
V At each tap location, allow sufficient trunk cable length for a
service loop to prevent pulling or twisting the cable.
V For each drop cable, provide a service loop to allow the connector to
be connected and disconnected at the network node device without
any strain on the cable. A service loop of 6 in (15 cm) minimum
radius is adequate for most installations.
V Install cable ties or clamps on each trunk cable segment as required
for strain reliefs, to prevent the cable from pulling on the tap.
V Install cable ties or clamps on each drop cable as required for strain
reliefs, to prevent the cable from pulling on the tap or node device
connector.
V Use additional ties or clamps as required to secure each cable from
flexing or other damage in areas of mechanical motion devices and
traffic.
