This is the kind of cable that is used in many Ethernet networks. There are four pairs of wires that make up the cable. It has a durable plastic separator to keep each pair separated throughout the cables. This means that each pair are twisting, so there is zero interference with other gadgets on the network. The wires are also bent at different intervals , so they won't cause interference between the pairs. If you are in an area where there's a great deal of Electromagnetic Interference (EMI), such as in a mechanical environment or a mechanical space, it's possible to utilize a shielded twisted pair and have an outer shielding that adds extra protection from EMI. Categories 5e, 6A, and 7 are typical choices for today's. Twisted-pair cable is limited to 295' for a horizontal run. Twisted pair cable is used in many ways. The standard station cabling used for computers as well as VOIP phones wireless access point, network cameras, access control and buildings maintenance equipment are only one of. It is among the most reliable types of cables, and when employed, network failures are much less frequent than when other cables are used.
Fiber optic cable can be utilized as a backbone cable, however it is being used more and more for station cables (think"FIOS"). Backbone cable means it connects Telecommunication Rooms within the same space. Fiber optic cables have huge capacity for broadband, allowing it to transport huge amounts and information at super fast speeds. Fiber cables can span huge distances(hundreds of meters) unlike copper cable. Since they perform such an intense job and data moves at such a distance, there are many layers of protective coating on these cables. Fiber cables transmit light as rather than electrical current. Fiber optic cables consume less power than high speed copper. Fiber optic cable is a great option for reliable, high-speed communications.
Cable paths must steer away from electrical fixtures as well as different sources for EMI (Electro Magnetic Interference). Make sure that cable paths are in reachable places on the ceiling for future cable runs, and to make it easier of maintenance. All paths should be run over corridors, hallways, or hallways. cables can enter rooms in circular 90-degree angles. Install a firestop sleeve putty at all points of the wall. Be mindful when pulling cables, so as not to over-bending them beyond the bend radius. This could result into a failure when testing. Do not attach cables to hanging ceiling slats, or even sprinkler pipes. They must be secured at minimum every 5' on horizontal runs and higher on vertical runs. J-hooks should be tied to the concrete deck on top. Use velcro wraps for every 5' , or less, after having done running cable in order to give your cable bundles an attractive finish.
