Exercise 1 – Fiber Optics Definitions
1. Crosstalk – The coupling or transfer of unwanted signals from one pair within a cable to another pair.
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
4. Simplex –
a. A link that can only carry a signal in one direction.
b. A fiber-optic cable or cord carrying a single fiber. Simplex cordage is mainly used for patch cords and temporary installations
5. Half-Duplex – A system in which signals may be sent in two directions, but not at the same time. In a half-duplex system, one end of the link must finish transmitting before the other end may begin.
6. Full-Duplex – A system in which signals may be transmitted in two directions at the same time.
7. Photodiode – A component that converts light energy into electrical energy. The photodiode is used as the receiving end of a fiber-optic link.
8. Amplitude Modulation – A method of signal transmission in which the amplitude of the carrier is varied in accordance with the signal. With respect to optical fiber cabling, the modulation is done by varying the amplitude of a light wave, common in analog/RF applications.
9. Analog Transmission – a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable.
10. Digital Transmission – The sending of information over a physical communications media in the form of digital signals.
11. Sample Rate – Defines the number of samples per unit of time (usually seconds) taken from a continuous signal to make a discrete signal.
12. Electromagnetic Wave – A wave of energy propagated in an electromagnetic field.
13. Refraction – The bending of a beam of light as it enters a medium of different
