Station Wiring Design
The following hardware and cabling is used:
• ‘‘Information Outlets’’ on page 160 (modular wall jacks)
• ‘‘Station Cables’’ on page 160
• ‘‘Closets’’ on page 161
• Site locations
• Satellite locations
A brief description of each of the above listed items follows. Ordering information is not
provided for station cables and information outlets.
Information Outlets
Information outlets are 8-pin modular wall jacks. Most of the outlets are wired with push-on
connections. Information outlets are also available that connect to a double modular plug-ended
4-pair station cable routed from the MDF, a site/satellite location, or an adapter.
Station Cables
For clarity, a station cable is either a 25-pair cable, multiple 25-pair cable, or 4-pair D-inside
wire (DIW) run from the equipment room, site/satellite location, or adapter to the information
outlets. The following station cables are available. See ‘‘Example of Extending 4-Pair Station
Cables’’ on page 163.
25-pair station cable
— Use between the equipment room and site/ satellite locations or
adapters. Use an A25D cable (male to male) between the equipment room and satellite closet.
Use a B25A cable between the equipment room and site closet or adapter.
Multiple 25-pair station cable
— Use between the equipment room and site/satellite locations
or adapters. This cable consists of individually sheathed 25-pair cables with a factory-installed
25-pair connector on each end. Use a male to female cable to connect between the equipment
room and site location or adapter. Use a male to male cable to connect between the equipment
room and satellite location. Staggered-finger cables are recommended for all multiple 25-pair
station cables and are available in both double-ended and single-ended types.
Single modular plug-ended 4-pair station cable
— Use this cable between adapters and
information outlets that require push-on connections. It can also be used when 4-pair station
cables are field- terminated on the 110-type terminal blocks in the equipment room or satellite
closet and modularly connected to information outlets. The station cables are available in the
following lengths:
• 10 ft (3.05 m)
• 25 ft (7.62 m)
• 50 ft (15.24 m)
