BICSI Installer 1 Questions & Answer,

100% Correct | Grade A+

25 - pair color code โœ”: White - Blue, orange, green, brown, slate Red - Blue, orange, green, brown, slate Black - Blue, orange, green, brown, slate Yellow - Blue, orange, green, brown, slate Violet - Blue, orange, green, brown, slate Fiber color code โœ”: Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose, Aqua NVP โœ”: Nominal Velocity of Propagation Insertion loss โœ”: The difference in the amount of power received before and after something is inserted into the circuit.

Resistance โœ”: Resistance is expressed in Ohms, and is the property of a conductor to resist the flow of electricity through it. V=IR Inductance โœ”: Is a property of an electromagnetic field built around a conductor that opposes any change in the current flow in a circuit Capacitance โœ”: is a property of conductors that allows storage of electric charges when potential differences exist between the conductors. Impedance (V) โœ”: Total opposition of current flow measured in Ohms American Wire Gauge (AWG) โœ”: 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)

Coaxial cable types โœ”: Series-6 and Series- 11 Coaxial connectors โœ”: Series-6 uses BNC and F connectors Series-11 uses F and N connectors Fiber connectors โœ”: SC, ST, and SST(LC or cladding โœ”: 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) โœ”: 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

โœ”: 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 โœ”: Multiple 250 um fibers bonded into a flat color coded ribbon. Can splice a bunch at a time. Fiber - Tight buffer diameter โœ”: 900 um Fiber - Acrylate coating diameter โœ”: 250 um OM โœ”: 850 nm OFL - 200 MHzโ€ขkm (3.5dB/km) 1300 nm - 400 MHzโ€ขkm (1.5dB/km) OM

Modal Bandwidth is described in terms of... โœ”: (MHz)(km) Ferrule Key Latching Mechanism โœ”: flat or pre-radiused end assures consistent connector orientation within couplers locks in place Straight Tip (ST) โœ”: One of the most common fiber-optic connectors, similar in style to the BNC connector in coax subscriber connector (SC) โœ”: A square snap coupling for fiber-optic cable, about 2.5 mm wide, used for cable-to-cable connections or to connect cables to network devices. It latches with a push-pull action similar to audio and video jacks. Small Form Factor (SFF)

โœ”: LC and MU an example of array connectors... โœ”: MPO Can terminate 6-72 optical fibers into a single ferrule Ohm's Law โœ”: V=IR Typical balanced twisted pair cable โœ”: 100 Ohms UTP 4 pairs blue, orange, green, brown (tip/ring) 8P8C - B pinout โœ”: White/orange Orange White/green Blue

1 trillion cycles โœ”: 1 Hz 60 Hz 1 KHz 1 MHz 1 GHz 1 THz Voltage, current, and amperes โœ”: P(Power)=V(voltage) x I(Current) What is bandwidth expressed in โœ”: analog frequencies (0Hz to 1MHz) AWG โœ”: Smaller number - bigger wire Higher number - smaller wire A balanced twisted pair has... โœ”: a nominal characteristic impedance of 100 Ohms

A unbalanced coaxial cable has... โœ”: a nominal characteristic impedance of 75 Ohms Category 3 Category 5e Category 6 Category 6A Category 8 โœ”: 16 MHz 100 MHz 250 MHz 500 MHz 2000 MHz 8P8C - A pinout โœ”: White/green Green White/Orange Blue
