Fiber Optics Technology

December 25th Fact-of-the-Day

Fiber optics technology provides a method to transmit information from one place to another that is superior to copper wires in many applications. Instead of sending electrical signals, modulated light is sent over insulated glass-fiber lines to a light-signal receiver. The light signals are immune to electric, magnetic and electromagnetic interference that affect transmissions over wires. Glass fiber lines tend to be lighter in weight than copper lines. They are not damaged by moisture. Light attenuation tends to be very low through glass fiber, so information can be sent great distances without repeaters. The spectral bandwidth is extraordinarily wide, which makes it possible to send a large number of high-speed information channels simultaneously over single lines. ©2004 Martek International All rights reserved.
