Resistance - Answer ️️ -Resistance is expressed in Ohms, and is the property of a conductor to resist the flow of electricity through it. V=IR Inductance - Answer ️️ -Is a property of an electromagnetic field built around a conductor that opposes any change in the current flow in a circuit Capacitance - Answer ️️ -is a property of conductors that allows storage of electric charges when potential differences exist between the conductors. Impedance (V) - Answer ️️ -Total opposition of current flow measured in Ohms American Wire Gauge (AWG) - Answer ️️ -A standard rating that indicates the diameter of a wire, such as the conducting core of a coaxial cable or the twisted pairs in a UTP cable. Megahertz (MHz) - Answer ️️ -one million hertz, especially as a measure of the frequency of transmissions Megabit (Mb) - Answer ️️ -Approximately one million bits. Often used as a measurement of data transfer throughput. Bandwidth - Answer ️️ -The amount of data that can be transmitted over a network in a given amount of time. Decibel (dB) - Answer ️️ -A unit used to compare the loudness of different sounds. Crosstalk - Answer ️️ -when data bleeds from one pair to another in a cable Alien Crosstalk (AXT) - Answer ️️ -Unwanted signal coupling from one permanent link to another USOC - Answer ️️ -Universal Service Order Code Coaxial cable types - Answer ️️ -Series-6 and Series-11 Coaxial connectors - Answer ️️ -Series-6 uses BNC and F connectors Series-11 uses F and N connectors Fiber connectors - Answer ️️ -SC, ST, and SST(LC or cladding - Answer ️️ -The glass or plastic shield around the core of a fiber-optic cable. Cladding reflects light back to the core in patterns that vary depending on the transmission mode. This reflection allows fiber to bend around corners without impairing the light-based signal. Multimode Fiber (MMF) - Answer ️️ -Larger core with multiple paths of light. Common for backbone and horizontal cabling in buildings. OM2 - Not recommended for new installs. OM3 - Higher bandwidth. OM4 - Highest bandwidth for MMF. 2000m/6500ft limitation. 850 nm and 1300 nm (nanometers) Singlemode Fiber - Answer ️️ -Smaller core with only one path of lights. Horizontal, riser, campus environments. 9 um core, 125 um cladding. OS1 - LAN, tight buffered construction, 1310/1550 nm OS2 - Outside Plant, 1310, 1490, 1550, 1625 nm 3000m/9842ft limtations. Ribbon Fiber - Answer ️️ -Multiple 250 um fibers bonded into a flat color coded ribbon. Can splice a bunch at a time. Fiber - Tight buffer diameter - Answer ️️ -900 um Fiber - Acrylate coating diameter - Answer ️️ -250 um OM1 - Answer ️️ -850 nm OFL - 200 MHz•km (3.5dB/k
