BICSI Installer 1
BICSI Installer 1 25-pair color code: Specifies the color combinations used in telecommunications cables, with each color paired with blue, orange, green, brown, and slate. - Fiber color code: Defines the standard colors used in fiber optic cables for identification: blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, and aqua. - NVP (Nominal Velocity of Propagation): Refers to the speed at which an electrical signal travels through a medium relative to the speed of light in a vacuum. - Insertion loss: The reduction in signal power resulting from the insertion of a device or component into a transmission line or optical fiber. - Resistance: The measure of opposition to the flow of electric current through a conductor, measured in Ohms (Ω). - Inductance: The property of an electrical conductor by which a change in current flowing through it induces an electromotive force (EMF) in the conductor itself. - Capacitance: The ability of a system to store an electric charge, typically between two conductors separated by an insulator. - Impedance (Z): The total opposition to alternating current in a circuit, combining resistance, inductance, and capacitance, measured in Ohms (Ω). - American Wire Gauge (AWG): A standardized system for specifying the diameter of electrically conducting wires. - Megahertz (MHz): A unit of frequency equal to one million hertz, commonly used to measure the frequency of electromagnetic signals. Megabit (Mb) ️Approximately one million bits. Often used as a measurement of data transfer throughput. Bandwidth ️The amount of data that can be transmitted over a network in a given amount of time. Decibel (dB) ️A unit used to compare the loudness of different sounds. Crosstalk ️when data bleeds from one pair to another in a cable Alien Crosstalk (AXT) ️Unwanted signal coupling from one permanent link to another USOC ️Universal Service Order Code Coaxial cable types ️Series-6 and Series-11 Coaxial connectors ️Series-6 uses BNC and F connectors Series-11 uses F and N connectors Fiber connectors ️SC, ST, and SST(LC or cladding ️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) ️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 ️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 n
