Use of fiber optic cables has significantly grown in the past few years.  Nowadays, fiber optic cables are used in a number of industries such as  medical, defense, telecommunication and broadcast industry. They are  used in networking to increase speed and accuracy of data transmission.  Broadcast companies also use these fibers for wiring HDTV, CATV and  other applications. In medical industry, they are used to light imaging  tools and lasers. Fiber optic cables are also utilized in wiring  submarines, air-crafts and other similar vehicles. These cables are  required to transmit data from one point to another. Cabling is usually  done by using optical fibers, which are thin, flexible and long strands  of ultra-pure glass. They use portions of manufactured glass which is  heated between 3000 and 4000 degrees. When an optical fiber is pulled,  it is monitored using a laser micrometer, to ensure that the diameter is  uniform from one end to the other. Optical fibers need to be highly  ...
