Aherne-Williams Fibre-Optic Telecommunications Systems: Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter‚ relaying the signal along the fiber‚ ensuring that the signal does not become too distorted or weak‚ receiving the optical signal‚ and converting it into an electrical signal. An optic-fibre is a small

Persaud NT1310 Unit 7 Exercise 1: Fiber Optics- Definitions 1. Crosstalk – The coupling or transfer of unwanted signals from one pair within a cable to another pair. Crosstalk can be measured at the same (near) end or far end with respect to the signal source. Crosstalk is considered noise or interference and is expressed in decibels. 2. Waveguides – A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH – (fiber-to-the-home):

Baldeo Persaud NT1310 Unit 7 Assignment 1: Refraction‚ Reflection and Optics A good example of refraction of light and reflection of light is a rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle‚ which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least
