The limiting conductor-load per unit size assumed for the purposes of design. The fastened transmitter/receiver device that a cell radio transceiver establishes a communication link with in order to achieve access to the public-switched phone network. The steel from which the connector, contact or other metallic accent is made and on which a number of metals or coatings could also be deposited. The metallic from which the connector, contact, or other piece part accessory is made and on which one or more metals or coatings could also be deposited. The seal preventing the passage of moisture or gases through the insulator and the gap between insulator and heart conductor or outer conductor of a connector or adapter.


A comparatively costly contact material with properties superior to brass or phosphor bronze. It is used for contact functions requiring repeated extraction and reinsertion due to its resistance to fatigue at excessive operating temperatures. Single-mode fibers which were modified to demonstrate reduced bend radius traits without attenuation modifications. Multiple conductor cable having a layer of insulation over the assembled insulated conductors. Number of layers of insulation on a conductor, or variety of layers of jacket on a cable. The raised portion on the front and/or back of the wire barrel crimp that gives a gradual entrance and exit for the wire strands without inflicting harm.


Insulated copper wire for making doorbell and thermostat connections in homes. A passive gadget that uses optical lenses with reflective coatings to control the split ratio and divide an optical beam into two or extra beams. The formal name for the ST connector, a selected slotted twistlock connector with 2.5-mm ferrule. Metal from which the connector parts are made and on which one or more metals or coatings may be deposited. The BRI contains 2B + D channels for carriage of signaling and consumer information.


The cabling used to connect entrance amenities, crossconnects, telecommunications closets, and gear rooms. The backbone might encompass either interbuilding and/or intrabuilding cabling. An intermediate stage in the response of sure thermosetting resins during which the fabric softens when heated and swells when involved with sure liquids, however could not completely fuse or dissolve.


A partition of electrically non conductive materials which will increase the electrical path between adjoining electrical circuits or an electrical circuit from floor. An insulated wire used for the interconnection of selector switches in computerized telephone exchanges. A system for matching impedance between a balanced to unbalanced line, often twisted-pair and coaxial cable. A cable consisting of one or more metallic symmetrical cable components . A cable having two equivalent conductors which carry voltages opposite in polarity and equal in magnitude with respect to ground. Any system added to the rear of a connector to reinforce the connector's operational characteristics.


It can embrace wire with a steel core clad wire, or plated or coated wire. A combination of biconical and log periodic antenna with an automated crossover community with a frequency range from 26MHz to 2 GHz. A amount derived by multiplying the number of conductors in a cable by the quantity of cable. Usually used to point plant capability or an annual requirement. A winding made non-inductive by winding together two wires carrying current in reverse directions. A broadband dipole antenna used to measure and produce electric fields from approximately 30 MHz to 300 MHz. A phenolic-bodied, threaded, spring-loaded, non-keyed connector with a cone-formed alignment area.


The resin in an uncured thermosetting adhesive is usually on this stage. A ray passing by way of the axis of the optical waveguide without any inside reflection.


A connector meeting in which the elements are bonded collectively utilizing an electrically acceptable adhesive in a sandwich construction to provide sealing against moisture. Main, or largest, portion of a connector to which other portions are connected. Outer cable overlaying utilized by managed inflation of the cured jacket tube then pulling the cable through it.
