Network Cabling Systems

Voice and Data Cabling - Network cabling carries the lifeblood of your organization - information. To minimize expensive data network problems and to add value to your business, River Valley Communications follows strict installation and testing guidelines adhering to EIA/TIA and BICSI.

Coax Cabling - A critical piece of the infrastructure puzzle for our legacy customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications and is till used widely even though in most arena's they have been replaced by modern solutions.

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 based on the complexity at site and requirements.

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 adhering to EIA/TIA standards.

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 cabling systems and use advanced splicing techniques for our installations.

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. We are the leading industry solutions provider in the DATA Centre arena and have wide levels of experience and expertise to understand customers needs and to put them to work.


Network Cabling Systems - Twisted Pair Cabling

Twisted Pair Cabling

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 3, 4, 5, 6 and 7). Over 95% of our copper installations are UTP versus shielded twisted pair (STP) and foiled twisted pair (FTP), both of which are rarely used.

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. Normally generated by over head or adjoining electrical lines running close to the data cabling.

In local area networks (LANs), failure to properly manage EMI can have an adverse effect on the integrity of the signal being transmitted. 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 5 cable has more twists per foot than Category 3 or 4 cables and, therefore, offers better protection from EMI problems.

All cables that we use adher or exceeds standards specified by EIA/TIA and BICSI.
