Network cabling today is used for many other purposes besides computer networking. Network cabling is also used as control cable in Building Maintenance Systems and Access Control Systems. Understanding Cable Type
Before you can really understand how cable networking works, you need to know about the various cables and how they work. Here is a rundown of the cables that are most commonly used for network cabling:
Unshielded/Shielded Twisted Pair – This is the type of cable that is used for many Ethernet networks. Twisted pair cable is limited to 295′ on a horizontal run. Twisted pair cable is used for many applications. Standard station cabling for computers and VOIP phones, wireless access points, network cameras, access control and building maintenance systems are just a few. Fiber Optic – Fiber optic cable is primarily used as backbone cable although it is being used more and more as station cable (think FIOS). Fiber cables can cover great distances(hundreds of meters) as opposed to copper cable. Fiber cables transmit light as opposed to electrical current. Fiber optic cable is a great choice for high speed reliable communications.
Coaxial Cable – Coaxial cable usually falls under the scope of work of the network cabling installation contractor. Coax will be used for the cable television locations within the space you are cabling. Network Cabling Components
RJ 45 Connector – The RJ-45 connector is installed on the end of a network cable. Contrary to popular belief wireless devices STILL need to be fed with network cabling.
Cable Supports – (Commonly called J-Hooks) Cable supports are mounted in the ceiling as a support structure for your cable bundles. Wire Managers – Wire managers are installed between patch panels and switches to manage patch cables. Firestop Sleeves – Firestop sleeves are a vital part of any network cabling installation these days. Cable Labels – All cables and termination points should have a unique label.
