Telecast-Fiber Systems specializes in fiber optics for television broadcast production. The company is one of the pioneers in the fiber optic industry and created many of the industry s firsts, such as the first commercial single mode fiber and cable. Telecast-Fiber Systems supplied systems for one of the first fiber optic network broadcasts in 1980, and the company has worked to improve the equipment for fiber television production since. The result is a family of fiber optic communications systems that provide transmission of virtually all the signals used in television broadcast production from digital video technology to the most basic of intercom systems interfaces. Telecast was formed in 1991 to develop products specifically for television broadcast production. The company s systems are used throughout the world by many networks and stations in some of the highest profile events. Telecast-Fiber Systems was founded in 1974 and is located in Worcester, Mass.
