Fiber Optics Illustrated Dictionary - Part 12

The Fiber Optics Illustrated Dictionary - Part 12 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 demarcate the end of one communication or section and the beginning of the next one especially in situations where many people are sending information through the same queue such as a print queue or 2 to identify the type of communication or the person to whom it belongs. bantam tube A squat electron tube with a normalsized base that was once commonly used in small appliances or battery-operated mobile devices like portable radios. Modem transistors have since made most types of vacuum tubes obsolete. See acorn tube. bar code Identification information and management code designed for optical scanning by a reading device. Black and white visual bar codes are familiar identifiers on consumer products. They assist the checkers in entering prices and adjusting inventory databases. Bar codes are frequently inserted on postal letters and packages that have been optically interpreted. In fact the information encoded into video and audio discs is stored via bar codes. Bantam port A connecting interface used on T1 systems for interfacing with receive and transmit e.g. DS 1 in out or external timing sources typically with balanced 100- or 120-ohm termination. A mini-Bantam may be used on T1 daughtercards for supporting an external monitor. In circuit testing the sleeve on the Bantam connection may be used to ground the circuit. Port Configurations - Bantam W W @@ I I Unlike RJ-45 left or bayonet-mount ports middle which have distinctive shapes a Bantam port is very simple and unassuming just a small round hole or dual holes for receive and transmit connections . bar generator A device used to generate horizontal or vertical bars on an output device to determine and adjust linearity. Baran Paul ca. 1926- A Polish-bom American engineer Baran is acknowledged as a significant Internet pioneer. He conceived a Distributive Adaptive Message Block Network a concept dubbed packet switching by Donald Davies while working at RAND Corporation on U.S.
