Exercise 1: Cabling definitions Horizontal cable- Horizontal Cable-The cabling between and including the telecommunications outlet and the horizontal cross-connect. Horizontal cabling is considered the permanent portion of a link; may also be called horizontal wiring. Backbone cable- is a cable connection between telecommunications or wiring closets‚ floor distribution terminals‚ entrance facilities‚ and equipment rooms either within or between buildings. This cable can service voice communications or data

AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC light where HVDC light converters are used for faster and efficient conversion of power. HVDC Light is a fundamentally new

fiber Fiber optic cable was once reserved for high-performance needs‚ but today it’s turning up in all kinds of networks. If you’re familiar with copper cable‚ you’ll quickly discover that fiber optic cable is a completely different animal. Not only is the installation process different for fiber‚ but also the troubleshooting process. Fiber optic cable is also far more fragile than copper cable‚ so there are more potential causes of trouble. I’ll discuss common fiber optic cable problems and how to

telecommunications rooms and equipment rooms. Patch cords: Any flexible piece of cable that connects one network device to the main cable run or to a patch panel. Connectors: A device attached to the end of a cable‚ receiver‚ or light source that joins to another cable or device. 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

equipment room. One advantage of using conduit to hold the cables is that conduit may already exist in the building. A drawback to conduit is that it provides a finite amount of space to house cables. Conduit should be a maximum of 60 percent full. This margin leaves room for future growth. It is better to use conduit if it is already available and fireproofed. Cable trays are typically wire racks specially designed to support the weight of a cable infrastructure. They provide an ideal way to manage a
