Fiber Optics Illustrated Dictionary - Part 15

The Fiber Optics Illustrated Dictionary - Part 15 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary which excessive voltage is detected and the circuit tripped or broken in order to prevent overload electrical fires or damage to appliances or the main panel. 2. In radio communications anyone who drops in on a channel to communicate when others are already engaged in conversation. 3. In public online forums a person who breaks into an ongoing conversation or thread with irrelevant or unkind and unwanted comments. breaking strength 1. An industrial measure of the force needed to break a specific structure or material or a combination of the two . Used in structural and safety design and selection and installation of appropriate wires and cables. breakout An exit point for electrical conductors wires cables etc. along the length of the circuit between the endpoints of the circuit. Breakouts can be used for additional installations or testing and diagnosis of the circuit. Breakouts are usually covered or capped in some way to prevent interference with the circuit and shock or fire hazards. breakout box A diagnostic instrument used to tap into an existing circuit to evaluate its functioning to see whether individual lines within a group are correctly connected and in some cases to detect which signals are being transmitted. Breakout boxes often have indicators such as tones or light-emitting diodes LEDs to help assess the line and may include jumpers to temporarily switch connections. One usefill application of a breakout box is to test a serial circuit since computer equipment manufacturers don t consistently follow the RS-232 or RS-423 specifications. In the case of a temporary need for a null modem cable e.g. for transferring information from one computer to another through telecommunications software a breakout box can be used to cross the transmit and receive lines. See breakout. Brewster s angle In the context of an electromagnetic wave encountering a dielectric material there is a particular angle called Brewster s angle at .
