Our current "age of technology" is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copper wire of a century ago to today's fiber optic cable has enabled the telecommunications, news and banking industries to expand their horizons and offerings while becoming increasingly more reliable and dependable.


The advent of Digital and HD-TV ensured this medium now comes to Broadcast Television, giving it an ever increasing ability to transmit more information at a higher quality, more quickly and over longer distances. It has and will continue to expand the boundaries of our technological development in all areas. Today's low-loss glass fiber optic cable offers almost unlimited bandwidth and unique advantages over all previously developed transmission media. Here are but a few of the wide range of benefits offered by fiber optic solutions over traditional copper wire or coaxial cable:


  • The ability to carry much more information and deliver it with greater fidelity than either copper wire or coaxial cable.
  • Fiber optic cable can support much higher data rates, and at greater distances, than coaxial cable, making it ideal for transmission of serial digital data.
  • The fiber is totally immune to virtually all kinds of interference, including lightning, and will not conduct electricity. It can therefore come in direct contact with high voltage electrical equipment and power lines. It will also not create ground loops of any kind.
  • As the basic fiber is made of glass, it will not corrode and is unaffected by most chemicals. It can be buried directly in most kinds of soil or exposed to most corrosive atmospheres in chemical plants without significant concern.
  • Since the only carrier in the fiber is light, there is no possibility of a spark from a broken fiber. Even in the most explosive of atmospheres, there is no fire hazard, and no danger of electrical shock to personnel repairing broken fibers.
  • Fiber optic cables are virtually unaffected by outdoor atmospheric conditions, allowing them to be lashed directly to telephone poles or existing electrical cables without concern for extraneous signal pickup.
  • A fiber optic cable, even one that contains many fibers, is usually much smaller and lighter in weight than a wire or coaxial cable with similar information carrying capacity. It is easier to handle and install, and uses less duct space. (It can frequently be installed without ducts.)
  • Fiber optic cable is ideal for secure communications systems because it is very difficult to tap but very easy to monitor. In addition, there is absolutely no electrical radiation from a fiber.


Still believe it is Cost Prohibitive? Remember Fiber is a universal medium:

Fiber can transport Digital Video, Analog Video, Digital Audio, Analog Audio, Data (RS-232, RS-422, RS-485) and Intercom, sometimes even on the same strand of fiber. Once you've laid down your basic infrastructure, refurbishing or changing configurations simply means moving the head ends around. This saves both time and money! The bandwidth potential of fiber means you need to pull far fewer cables during the initial install, again saving you time and money. Each setup requires less cables and bulk connectivity ensures a much faster setup and teardown—no wasted overtime, etc.

We find them to be particularly useful for both beginners and advanced users of Fiber Technology as they are both informative and well researched, from the pen of a very experienced industry veteran.
