Have you ever wondered about what exactly connects networks and computers to one another? Network cable along with the hardware (network hubs, switches as well as demarcation equipment) is responsible for computers being able connect and transfer data between intranets (internal networks) and the internet. Network cabling is now used for a myriad of purposes other than computer networking. It is used to transmit video to security camera systems, as well as video for cable TV and AV (Audio/Visual) applications. Network cabling may also be utilized as a control cable within Building Maintenance Systems and Access Control Systems. There are several different types of cables that are used for this purpose. These include unshielded T-twisted pair, shielded pair, fiber optic and coaxial. In certain instances, only one kind of cable is employed in a network, while in other cases various kinds are used. Wireless networks are becoming more and more popular but always remember you will require network cabling to run the wireless system. There is still two things that make network cabling superior than a wireless network as it is far more safe and reliable.

This is the type of cable used for many Ethernet networks. There are four pairs of wires inside the cable. There is a strong plastic separator that keeps each pair isolated through the line of cable. Each pair of wires are bent so that there is in no way to interfere with devices that are connected to this network. The wires are also twisted at different intervals to ensure that they will not cause interference among each other. If you're in a situation where there is a significant amount of Electromagnetic Interference (EMI), like a mechanical space you could choose to use shielded twisted pair which comes with an outer shielding which provides additional protection against EMI. Categories 5e, 6, 6A and 7 are the general choices for today's. Twisted pair cable is only available to 295' on a horizontal run. Twisted pair cable can be used in a variety of applications. The standard station cabling used for computers as well as VOIP phones wireless access points, access control, network cameras and buildings maintenance equipment are only a few. It is among the most reliable types of cables. And when they are in use, network failures are less frequent than when other cables are utilized.

Fiber optic cables are primarily utilized as a backbone cable, however it is increasingly being used in the form of station cable (think"FIOS"). By backbone cable I mean it connects Telecommunication Rooms within the same space. Fiber optic cable comes with huge capacity for broadband, allowing it to carry massive amounts of information at extremely fast speeds. Fiber optic cables can reach great distances(hundreds of meters) as opposed to copper cable. Since they work at a high rate and the information moves over such long distances, there are many layers of protective coatings on these cables. The fiber optic cables transmit light as instead of electrical current. Fiber optic cables require less energy than high-speed copper. Fiber optic cable is a fantastic choice for high-speed reliable communications.

Cable paths need to steer away from electrical fixtures as well as additional sources that could cause EMI (Electro Magnetic Interference). Make sure that cable paths are in reachable portions of the ceiling to allow for future cable runs as well as ease of maintenance. All routes should be placed across corridors or hallways. cables must enter each room on circular 90-degree angles. Install a firestop sleeve , or putty on every penetration of a fire wall. Take care when pulling cables, so as not to stretch them beyond their bend radius. This can cause failure in testing. Do not connect cables to fixtures on the ceiling, such as sprinkler pipes. They should be tied at least every 5' on horizontal runs and more often for vertical runs. J-hook supports should be anchored on the concrete deck above. Make use of velcro wraps each 5' or so once you've completed running cable to give your cable bundles an appealing look.
