made of high-quality silica glass‚ but they can both be made of plastic as well. Connecting two optical fibers is done by fusion splicing or mechanical splicing and requires special skills and interconnection technology. Diagram of a fiber optic cable Fiber optics would not be possible without total internal reflection. When light hits a medium of lesser index of refraction‚ the ray is bent away from the normal‚ so the exit angle is greater than the incident angle. The exit angle will then approach

1. A 1.4M Hz carrier is modulated by a music signal that has a frequency components from 20 Hz to 10k Hz. Determine the range of frequencies generated for the upper and lower sidebands. Solution: Upper Side Band = 1‚ 400‚ 000 Hz + 20 Hz = 1‚400‚ 020 Hz Up to = 1‚ 400‚ 000 Hz + 10‚ 000 Hz = 1‚ 410‚ 000 Hz Lower Side Band = 1‚ 400‚ 000 Hz – 10‚ 000 Hz = 1‚ 390‚ 000 Hz Up to = 1‚ 400‚ 000 Hz – 20 Hz = 1‚ 399‚ 980 Hz 2.
