Cable in the running for a Network Operations Center is a challenge, you have a variety of cable types for different needs. When it comes to the physical construction of the cables, there are four basic types to consider.
The first, almost all of these cables are a number of different pairs UTP "or" cable UTP, there are two pairs of twisted wires Comer, wrapped in a coating of polyurethane. UTP uses several features ofpropagation of electromagnetic waves to send signals, by varying the differential voltage on the wires. There are other types of cables (fiber and shielded cables are two), but if you do not have their specific advantages, twisted-pair copper is the most profitable. (Glass fiber offers higher bandwidth, but are much more expensive and a little 'fragile, shielded cable adds the cost of services, but not, and is usually used in places whereelectromagnetic radiation on the power cords can cause problems.)
Twisted pair copper cables, there are several subtypes. Stranded is the most common type - if you plug a network or an Ethernet cable from the router to a computer, this is the most likely. It consists of pieces of copper wrapped together in an insulator, over long distances, the signal loses its strength and has the advantage of being cheaper and flexible, and in the end it is easiertorque curve or a stranded wire to meet a given.
Flat cable uses a larger wire insulation in each run, has big problems with the electrical performance, which means in this context continue to transmit data with fewer losses. Most of the special cable wiring in buildings that were built in network cabling by the sound. If you've never had the traction cable through the rigid walls or ceiling, this is the type of cable that you had your handsexperience.
If you've heard of CAT5 cable (or CAT3 or CAT5) and someone had to sell or CAT6 CAT7, you see one of the key differences between the wire and drive there - the transmission distances. Transmission distance for a cable goes to the ability of cable to bring electricity - often leads to harness the power with less loss over distance, improved insulation also improves the transmission distances.When running more wires together (as the standard cable) can approximate the cable is fixed, it is not so effective and powerful, but the flexibility and lower costs are good performance.
CAT 6 cable is CAT5 cable with better shielding and a little more often, CAT 5 cable is a CAT5 CAT6 with the same screen. CAT7 wired to one thousand meters (a mile!) And is taller and more often end insulators. Note that neitherO CAT6 CAT7 recognized by today's standards - these cables as "draft-n" wireless, something that hardware manufacturers are making a product in advance of the current rule being finalized, but parts of it are released.
Both CAT6 cables and CAT7 considerably stiffer and more difficult to walk around corners, as expected, and are more expensive.
The real question is "What kind of cables do I really need this project?" You can savesignificant cost to only the cables you actually need, instead of walking CAT7 wiring for a couple of length 10 meters, where it offers no advantage over cheaper running.
