The Fiber Optics Illustrated Dictionary - Part 16 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 productivity applications demo programs and clipart libraries. 2. Individual wires or cables combined or interwoven to form a bundle for ease of handling and installation. Bunsen cell A type of cell devised by . von Bunsen that was an adaptation of an early wet cell in which the positive electrode was suspended in a bath of contained nitric acid separated from the outer electrolyte solution so that hydrogen would be oxidized and the cell depolarized. See dry cell wet cell von Bunsen . buried cable An underground cable installation that cannot be altered without disturbing the soil or accessing the cable under the soil through some entrance point. Buried cables are more aesthetic as they do not clutter the landscape with utility poles and wires but may be less easy to access to make changes or repairs. See Call Before Digging. burn-in A diagnostic preliminary operation sometimes at high temperatures to test devices and circuits in order to identify those likely to fail. In electronics many problems will show up early in the first few weeks of operation or under stress from heat and humidity. Sometimes called early failure period. burn-in monitor An undesirable ghost image on the coating inside a cathode-ray tube CRT monitor resulting from the persistent display of the same image or similar images. Monitor bum-in can be prevented by turning the monitor off when not in use and using screen savers that darken the screen completely or second-best that move around small low-contrast images.
