Have you ever wondered what the thing that connects computers and networks to each other? Network cable together with the associated hardware (network hubs, switches and demarcation equipment) is responsible for computers being able to transfer and connect data across intranets (internal network) and over the internet. Network cabling is now used in a variety of ways, not just for computer networking. It can be used to transmit video to security camera systems as well as video to Cable TV or AV (Audio/Visual) programs. Network cabling is also employed as a control line in Building Maintenance Systems and Access Control Systems. There are numerous types of cables being used for this function, including unshielded twist, shielded pair in addition to fiber optic and COAX. In certain situations, only one kind of cable is used for a network, when in other cases, many different types are utilized. Wireless systems are becoming increasingly prominent, but you must remember that it is still necessary to connect network cables to support the wireless system. There are two factors to make network cabling better than a wireless network It is more secure and reliable.

This is the type of cable that is used in many Ethernet networks. There are four wires inside the cable. The cable is protected by a tough plastic separator that keeps each pair completely isolated throughout the line of cable. Both pairs are made to be twisted, ensuring zero interference with other gadgets that are connected to that same network. They are also twisted at different intervals , so they will not cause interference between themselves. In situations where there's a significant amount Electromagnetic Interference (EMI), like in a space with mechanical components you could choose to use a shielded twisted couple that comes with an outer shielding that adds an extra layer of protection against EMI. Category 5e, 6A, and 7 are the most common selections today. Twisted-pair cable is limited to 295' in an horizontal run. Twisted Pair cable is used for many applications. Standard station cabling for computers and VOIP phones, wireless access points, access control, network cameras along with building and construction maintenance are but the most common. This is one of the most reliable types of cables, and when used, network issues are less common than in the case of other cables.

Fiber optic cables are primarily used for backbone connections, though it is being used more and more as station cable (think of FIOS). By "backbone" cable, I mean it connects Telecommunication Rooms within an area to one another. Fiber optic cables boast huge capacity for broadband, allowing it to transfer large amounts and information at super fast speeds. Fiber optic cables can reach great distances(hundreds of meters) unlike copper cables. Because these cables must work hard and data is transferred over long distances there are numerous layers of protective coatings for their fiber optic cables. Fiber optic cables transmit light opposed to electrical current. Fiber optic cable requires much less energy than high-speed copper does. It is a great option for reliable, high-speed communications.

Cable paths need to steer free of electrical light fixtures as well as another source for EMI (Electro Magnetic Interference). Maintain cable paths in a safe areas of the ceiling for future cable runs and for ease of maintenance. All paths must be located above corridors or hallways and cables should be inserted into individual rooms using circular 90-degree angles. Install a firestop cover or putty on all entrances to an fire wall. Be mindful when pulling cables in order not to cause them to bend beyond their bend radius. This can result in a failure in conducting tests. Make sure you don't connect cables to water pipes on ceilings. They must be tied at least every 5' on horizontal runs, and even more frequently on vertical runs. J-hook support should be fixed to the concrete deck above. Utilize velcro wraps at least every five feet or so once you've finished running cables to provide your cable bundles with the perfect look.

Tc tray cables are installed in cable trays, ducts and conduit; They can also be used in direct burial applications. Cable trunking is a manufactured enclosure for the protection of cables.
