CABLE DESIGN

October 21, 2011

There are 2 basic cable designs in fiber optics, loose-tube cable and tight-buffered cable. The loose-tube cable is used in most of the outside plant installations with the tight-buffered cable being primarily used inside buildings.

TIGHT-BUFFERED CABLE

With tight-buffered cable designs, the buffering material is in direct contact with the fiber. This design is suited for "jumper cables" which connect outside plant cables to terminal equipment, and also for linking various devices in a premises network. Multi-fiber, tight-buffered cables often are used for intra-building, risers, general building and plenum applications.

In 1870, a man by the name of John Tyndall (pictured right) showed that light follows the curve of a stream of water pouring from a container. This simple experiment led to the development of applications for this phenomenon. A Mr. John Logie Baird patented a method of transmitting light in a glass rod for early color TV.

In 1970, Corning developed the first optical fiber capable of maintaining the strength of laser light signals over significant distances. And in 1978, Corning developed the loose tube fiber optic cable design which has become the industry standard; manufactured and installed the first single mode optical fiber cable.
