Z100-TYPE HARDWARE
installed 25-pair connectors on both ends. Staggered-finger cables are recommended
for all multiple 25-pair station cables.

Nonconnectorized 4-pair station cable—This cable cannot be used with any of the
Z100 hardware unless a MOD-4 (modular 4-pin plug—Comcode 403 617 699) is
installed on one end or "junction boxes" are provided.
Single modular plug-ended 4-pair station cable—This cable is used between adapters
or connector modules equipped with Z204A1 connecting units and information outlets
with push-on connections. The station cables are available in the following
lengths:
10 feet ( 3.0 m)
25 feet ( 7.6 m)
50 feet (15.2 m)
75 feet (22.9 m)
100 feet (30.5 m)
150 feet (45.7 m)
200 feet (61.0 m).
●
Double modular plug-ended 4-pair station cable—This cable is typically cut and used
to provide nonstandard length runs between adapters or connector modules equipped
with Z204A1 connecting units and information outlets with push-on connections. It
can also be used between adapters or connector modules equipped with Z204A1
Connecting Units and modularly connected information outlets. It is available in the
same lengths as the single modular plug-ended cable (see Note).
Note: If a 4-pair station cable length longer than 200 feet (61.0 m) is required,
a 451A in-line adapter (double-ended modular female connector) is attached to
the cable and a second 4-pair cable is plugged into the adapter for the
additional distance (see Figure 2-56). The 451A in-line adapter is available in
grey (Comcode 103 942 272) or ivory (Comcode 103 786 240).
