Data cabling services

Cabling of data and voice systems is often ignored by many companies until the last minute just before relocation or new building takes place. Cabling is the backbone of any computer network; it ties all the components of the network together therefore it should receive as much careful consideration as any other network component.

Different type of cables used for network installation is:

  • Coaxial cabling is the primary type of cabling used by the cable television industry and is also widely used for computer networks, such as Ethernet. It is more expensive than standard telephone wire; it is much less susceptible to interference and can carry much more data than a telephone wire.
  • Twisted pair cable is created for high signal integrity. Some are unshielded while others are shielded. It is used in structured cabling for computer networks, token ring, basic voice services, and ATM.
  • Optical Fiber: It is further categorized into:

      • Single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm.
      • Multimode optical fiber is made of glass fibers, with common diameters in the 50-to-100 micron range for the light carry.
