TAILIEUCHUNG - Fiber Optics Illustrated Dictionary - Part 91

The Fiber Optics Illustrated Dictionary - Part 91 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 street price The price paid for a product after shopping around as opposed to suggested list or suggested retail the price the wholesaler or manufacturer has designated for the product which is usually higher due to dealer discounts. The suggested list price is often imprinted on the product packaging and overlaid with a lower dealer price. The street price may equal the dealer s price or may be a commonly negotiated price through discounts volume and competitive pricing dealers often offer a street price much lower than the list price. The street price may also be higher than list price. For example a ticket for a popular rock concert sold by street hawkers an hour before showtime may have a street price much higher than the original ticket price the scalped price stringed insulators Electrical insulating objects mounted in multiples in order to increase the spacing distance to what is needed between a conducting line and its supporting structure. Higher voltage lines mounted overhead on utility poles or high voltage towers tend to require a longer string of insulators that can be directed away from the pole or cross arm. The insulators are commonly strung in single rows or in a V configuration. Depending upon their configuration and the number of strings it may be difficult to access and maintain stringed wires from cherry picker bucket maintenance vehicles. Climbers manually scaling utility poles with strung insulators must also be careful not to move within the minimum air distance MAD arcing zone which is especially tight in V configurations. The arcing zone is related to the length of the insulating siring. See suspension insulator. stringing The process of running wire or cable especially as applied to stringing utility wires along outdoor utility poles. stringing block See stringing roller. stringing rope A narrow-gauge rope used to help string lines through narrow walls conduits or stringing rollers.
