Network Cabling Systems - Voice and Data Cabling
Cat 5, Cat 6 Cable
Today, your network cabling system carries the lifeblood of your organization - information. The installation, material, quality of cable and testing procedures are all much more critical in data wiring than in voice. The main reason for this is that networks today are designed to carry large amounts of information at incredible speeds. To accomplish this over unshielded twisted pair cable (UTP), many different criterion must be met.
Who sets the criteria and standards for network cabling? Well, the three major players are The Institute of Electrical and Electronics Engineers (IEEE - commonly called I-triple-E ) who work on developing new protocols, the American National Standards Institute (ANSI), the Telecommunications Industry Association / Electronic Industry Alliance (TIA/EIA) who issue the standards and testing procedures and BICSI (Building Industy Consulting Service International) who helps in the advancing of transport systems.
Note on BICSI - BICSI is a professional association supporting the information transport systems (ITS) industry. ITS covers the spectrum of voice, data and video technologies. It encompasses the design, integration and installation of pathways, spaces, fiber- and copper-based distribution systems, wireless-based systems and infrastructure that supports the transportation of information and associated signaling between and among communications and information gathering devices..
Suffice it to say that these people have been busy over the past 12 years - as we've seen network speeds increase from 10 million bits of information per second, over Category 3 wire, back in 1991 to 1 billion bits (called Gigabit Ethernet) today. With bandwidth increasing and reliance on the network at all time high, getting information to where it needs to be is becoming more challenging than ever. Ask any IT Manager what their most common network problem is and you will most likely hear would be about cabling issues. In fact, cabling problems, which account for over 70% of network problems, cost companies millions annually. And this is one area that is most neglected over the electrical system since this carries only few DC volts through them which can in no way harm humans.
The most common problems are:
- Low attenuation Poor NEXT (near-end crosstalk),
- Poor ACR (attenuation-to-crosstalk ratio)
- Poor delay skew (data arrives at different times)
- Poor return loss (also known as "echo")
- Poor ELFEXT (equal-level far-end crosstalk) numbers for cable,
- connecting hardware and
- channel Splices in cable Mis-labeled cables.
All of these problems can be avoided if the cabling is installed and tested properly. The cable must be installed following strict and specific guidelines and the testing must be done using the right equipment calibrated for the latest standards (called certification). River Valley Communications provides this with each cabling installation.
