Industry:Telecommunications
A substance in which an electric field may be maintained with zero or near-zero power dissipation, i.e., the electrical conductivity is zero or near zero. Note 1: A dielectric material is an electrical insulator. Note 2: In a dielectric, electrons are bound to atoms and molecules, hence there are few free electrons. 2. Pertaining to a substance that has a zero or near zero electrical conductivity.
Industry:Telecommunications
A substance surrounding the buffer tubes of a fiber-optic cable, to prevent water intrusion into the interstices in the event of a breach of the jacket.
Industry:Telecommunications
A substance, resembling petroleum jelly in viscosity, that surrounds a fiber, or multiple fibers, enclosed in a loose buffer tube. Note: This gel serves to lubricate and support the fibers in the buffer tube. It also prevents water intrusion in the event the buffer tube is breached. 2. Index-matching material in the form of a gel. Synonyms index-matching gel, matching gel.

A substance, usually a liquid, cement (adhesive,) or gel, which has an index of refraction that closely approximates that of an optical fiber, and is used to reduce Fresnel reflection at the fiber endface. (FAA) Note 1: An index-matching material may be used in conjunction with pairs of mated connectors, with mechanical splices, or at the ends of fibers. Note 2: Without the use of an index-matching material, Fresnel reflections will occur at the smooth endfaces of a fiber. These reflections may be as high as -14 dB (i.e., 14 dB below the level of the incident signal. ) When the reflected signal returns to the transmitting end, it is reflected again and returns to the receiving end at a level that is (28 plus twice the fiber loss) dB below the direct signal. The reflected signal will also be delayed by twice the delay time introduced by the fiber. The reflected signal will have no practical effect on digital systems because of its low level relative to the direct signal; i.e., it will have no practical effect on the detected signal seen at the decision point of the digital optical receiver. It may be noticeable in an analog baseband intensity-modulated video signal.
Industry:Telecommunications
A Subsystem containing its own implementation of the reference monitor concept for those resources it controls. Secure subsystem must depend on other controls and the base operating system for the control of subjects and the more primitive system objects.
Industry:Telecommunications
A suffix that is preceded by a decimal (". ") and that is appended to a computer file name. Note: Common filename extensions with their meanings are:. Wpd = a type of word-processing document. Doc = a type of word-processing document. Exe = executable code or a self-extracting archive file. . Gif = a graphical interchange format (graphics file. )txt = a text file. 2. Proprietary HTML tags that are recognized by a single Web browser or by those Web browsers developed by a single company.
