Unit 4 Exercise 1: Cabling – Definitions
Horizontal Cable- The cabling between and including the telecommunications outlet and the horizontal cross-connect. Backbone Cable- A cable connection between telecommunications or wiring closets, ﬂoor distribution terminals, entrance facilities, and equipment rooms either within or between buildings. Patch Cords- Any ﬂexible piece of cable that connects one network device to the main cable run or to a patch panel that in turn connects to the main cable run. Connectors- With respect to cabling, a device attached to the end of a cable, receiver, or light source that joins it with another cable, device or ﬁber. A connector is a mechanical device used to align and join two conductors or ﬁbers together to provide a means for attaching and decoupling it to a transmitter, receiver, or another ﬁber. Conduit- A rigid or ﬂexible metallic or nonmetallic raceway of circular cross section in which cables are housed for protection and to prevent burning cable from spreading ﬂames or smoke in the event of a ﬁre. Racks- A frame-like structure where patch panels, switches, and other network equipment are installed. The typical dimension is 19 inches. Punch-Down Blocks- A generic name for any cross-connect block where the individual wires in UTP are placed into a terminal groove and “punched down” with a special tool. The groove pierces the insulation and makes contact with the inner conductor. Consolidation Points- A location deﬁned by the ANSI/TIA/EIA-568-B standard for interconnection between horizontal cables that extends from building pathways and horizontal cables that extend into work area pathways. Crimpers- A device that is used to install a crimp-on connector. Crimping involves the act of using the crimping tool to install the connector. Fish Tape- Also called ﬁsh cord. A tool used by electricians to route new wiring through walls and electrical conduit. Cable Toner- Device that ensures electricity...
