• 75 ft (22.86 m)
• 100 ft (30.5 m)
150 ft (45.72 m)
•
• 200 ft (61 m)
NOTE:
If more than 200 ft (61 m) of 4-pair station cable is required, a 451A in-line adapter
(double-ended modular female connector) is attached to the cable and a second 4-pair
cable of the required length is plugged into the adapter. See
Station Cables.
Double modular plug-ended 4-pair station cable
length runs between adapters and information outlets with push-on connections. It can also be
used between adapters and modularly connected information outlets. It is available in the same
lengths as the single modular plug-ended cable.
—
Bulk Cable Same as the 25-pair cable or multiple 25-pair cable; however, the bulk cable is
not equipped with connectors. Use this cable between the equipment room and satellite closets
when both are equipped with punch-down type terminal/connecting blocks.
—
4-pair station cable Use this cable when 4-pair station cables are to be field-terminated on
the 110-type terminal blocks in the equipment room or satellite closet and the information
outlets require push-on connections

Closets

Site Locations

Site locations are closets that provide a point in the station wiring for the administration of
remote powering. Adapters are used at site locations to terminate the 25-pair station cables and
provide connection points (modular jacks) for power adapters and 4-pair station cables.
The258A and BR2580A adapters plug into a 25-pair female cable connector. These adapters
divide the 25-pair cable into six 4-pair (modular jack) circuits. See
Adapters'' on page 163.
The 356A adapter plugs into a 25-pair female cable connector. See
164. The 356A adapter divides the 25-pair cable into eight 3-pair circuits. Although the circuits
are 3-pair, the adapters modular jacks will accept the 8-wide modular plug used on the 4-pair
station cable.
!
CAUTION:
Adapters wired similarly to the 356A should not be used. Their jacks do not accept 4-pair
plugs.
