Voice & Data Cabling

Cabling Design & Installation

GETATECH can help you meet your communications cabling objectives.

• Voice Cabling Services - Our installation techniques provide customers with the flexibility to install any combination of VoIP phones, modems and analog lines at any location.
• Data Cabling Services - Network cabling carries the lifeblood of your organizations  information. To minimize expensive data network problems, GETATECH follows strict installation and testing guidelines.
• Coax Cabling Services - 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 Services - 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 Services - 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 Services - We install, terminate and test multi-mode and single-mode fiber. This includes both indoor and outside plant fiber. We keep abreast of advances in manufacturing, termination and testing standards of fiber optic cable.
• Server Room Installation Services - The server room is the centralized brain of your structured cabling system. We have the knowledge and experience to design and install it according to the highest standards.
  

  Data Cabling

  Cat 5, Cat 6 Cable

  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 criteria must be met.

  The criteria and standards for network cabling are developed and determined by the Institute of Electrical and Electronics Engineers (IEEE) work on developing protocols, the American National Standards Institute (ANSI), and the Telecommunications Industry Association / Electronic Industry Alliance (TIA/EIA) who issue the standards and testing procedures.

  With bandwidth increasing 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 common network problem is and you will most likely hear them rant about cabling issues. In fact, cabling problems, which account for most network issues and costs companies millions of dollars annually.

  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)
• Impedance
• Poor return loss (also known as "echo")
• Poor ELFEXT (equal-level far-end crosstalk) numbers for cable, connecting hardware and channel
• Splices in cable
• Unlabeled or Mislabeled cables

GETATECH avoids these problems by testing and certifying each cable with the latest cable testing and certification equipment.  We then provide a labeling system along with a cabling map and up-to-date documentation to make your job easier.

Coaxial Cabling

Coaxial cables carry a nominal impedance of between 35 and 185 ohms. The three most common coax cables are 50 ohms (most widely used in thin-net Ethernet), 75 ohms (the cable your most likely using at home for your TV or cable modem) and 93 ohms, which is rarely used.

Coax cable can support much higher bandwidths than unshielded twisted pair (UTP) cable. The most efficient transfer of energy, over coax, occurs when all parts of the system have the same impedance. For example, a transmitter, interconnecting cable, and receiver should all have matching impedance. This need for impedance matching is especially critical at higher frequencies, where the consequences of mismatches are more severe.

Knowing how to install and terminate coax cable properly is critical to achieving impedance matching. Knowledge and selection of the best available materials greatly increases efficiency.

The most common type of coax, called Flexible Coax, is a flexible cable, which uses a braided shield of extremely fine wires. This braid helps to make the coax flexible, but at a cost: energy or RF (radio frequency) signals leak through the small gaps in the braid. To combat this attenuation (energy loss), manufacturers have added several layers of braid and placed thin foil between the layers. This provides better coverage for greater shielding effectiveness. We normally use a quad shield (two layers of braid, two of foil) for 75-ohm applications.

Even though coax makes up a small percentage of our total installations, it is still 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 is closely associated with coaxial cable, because most video applications require coax, but we also install twisted pair cable for certain video applications.

We also install wiring for security and surveillance systems.
