Voice and Data Cabling - Network cabling carries the lifeblood of your organization. $nbsp; To minimize expensive data network problems, Aonica Infrastructure Solutions follows strict installation and testing guidelines. Coax Cabling - A critical piece of the infrastructure puzzle for our customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications. Video Cabling - Video cabling can be closely associated with coaxial cable, because most video applications require coax, but we also install twisted pair cable for certain video applications. Twisted Pair Cabling - Unshielded Twisted Pair has been designed for use in voice applications and local area networks. Because of the relatively low cost, this cable is widely used and is available in several different performance categories. Fiber Optic Cabling - We install, terminate and test multi-mode and single-mode fiber. We've kept abreast of advances in the manufacture, termination and testing standards of fiber optic cable. Data Center Cabling - Because the server room is the centralized brain of your structured cabling system, we take special care to design and install it according to the highest standards.

Unshielded Twisted Pair (UTP) has been designed for use in voice applications and local area networks. Because of the comparatively low cost, this cable is widely used and is available in several different performance categories (Categories 5, 6 and 7). The majority of copper installations are UTP versus shielded twisted pair (STP).

Electromagnetic interference is present in all types of cabling to some degree. There are two basic types of electromagnetic interference (EMI) that cable engineers worry about-electromagnetic emissions and electromagnetic immunity. Emissions refer to energy that is radiated by the cable, and immunity is the ability of the cable to reject outside signals. In local area networks (LANs), failure to properly manage EMI can have an adverse effect on the integrity of the signals being transmitted and received as noise margins are reduced.

In an unshielded cable, careful design of the cable and the associated electronic equipment results in a "balance" of the currents in the two conductors of a pair. That is, the currents in the two conductors are equal in magnitude but flowing in opposite directions. Proper installation and termination of the cable is also critical to maintaining this balance. In a balanced system, there is very little radiation of EMI since the external field from one conductor is effectively canceled by the external field from the other conductor of the pair.

Generally, the more twists per foot of cable, the better the cable is electrically balanced. Category 6 cable has more twists per foot than Category cable and, therefore, offers better protection from EMI problems. In category 7 cable each twisted pair has its own shield as well as an overall shield. The consequent improvement in crosstalk and EMI rejection enables category 7 to offer performance up to 10 Gbit/s.
