Voice & Data Cabling

InnovaGlobal's National Cabling Division:

    Network cabling provides the heartbeat of your organization. To limit costly data network issues, InnovaGlobal's Infrastructure Solutions produces strict installation and testing guidelines. The installation, material, quality of cable and testing techniques are all considerably more critical in data cabling than on the voice cabling side. The main reason for this is that networks today are intended to carry large amounts of information at extraordinary speeds. To accomplish this over unshielded twisted pair cable (UTP), numerous requirements must be met.


    Who sets the criteria along with standards for network cabling? Well, the three significant participants are The Institute of Electrical and Electronics Engineers (IEEE - commonly called I-triple-E ) who work on establishing new protocols, the American National Standards Institute (ANSI), and the Telecommunications Industry Association / Electronic Industry Alliance (TIA/EIA) who issue the standards and testing methods. Adequate enough to say that these people have been busy over the past 12 years - as we've seen network speeds improve 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 improving and reliance on the network at an all time high, getting information to where it needs to be is becoming more challenging than ever. Ask any IT Manager what their most typical network problem is and you will most likely hear them rant about cabling issues. In fact, cabling challenges, which account for over 50% of network problems, cost companies millions annually. The most common issues are:

  • Low attenuation (slow loss of intensity)
  • Poor NEXT (near-end crosstalk)
  • Poor ACR (attenuation-to-crosstalk ratio)
  • Poor delay skew (data arrives at different times)
  • Impedance
  • Poor return loss (also known as "echo")
  • Poor ELFEXT (equal-level far-end crosstalk) numbers for cable, connecting hardware and channel
  • Splices made in cable
  • Mis-labeled cables

    Most of these issues can be avoided if the cabling is installed and tested appropriately. The cable needs to be installed following strict and specific rules and the testing must be done using the appropriate equipment calibrated for the latest standards (called certification). InnovaGlobal provides this with EVERY cabling installation.
