BICSI 1 & 2 EXAM Study Guide | PassGuaranteed
Code - ✔✔Rule intended to ensure safety during installation, use, disposal. Typically invoked
and enforced by government. Address safety of persons, property and environment. Include:
Electrical, Building, Fire, Environmental, Safety. When adopted by Authority Having Jurisdiction
they have the force of law.
Standard - ✔✔Establish a basis to compare, measure or judge: Capacity, Quantity, Value,
Quality, Performance, Limits, Interoperability.
OLTS - ✔✔Optical Loss Test Set
OTDR - ✔✔Optical Time Domain Refractometer
Transmition - ✔✔The movement of information in the form of electrical or optical signals in
analog or digital form.
Simplex lines - ✔✔Transmit in one direction only
Half-duplex lines - ✔✔Transmit in either direction, but only one direction at a time
Full-duplex lines - ✔✔Transmit in both directions at the same time
The only common limiting factors are - ✔✔Faulty or improper system design or installation
techniques
Frequency - ✔✔The number of cycles a signal is repeated in a given time period
,Hertz - ✔✔The rate of change in one second
1,000 Hz is - ✔✔1 kHz
1,000,000 Hz is - ✔✔1MHz
1,000,000,000 Hz is - ✔✔1GHz
Bandwidth is - ✔✔The range between the highest and the lowest frequencies of a
communications component
Analog signals - ✔✔Utilize continuously varying electrical signals
Digital signals - ✔✔Are discontinuous, have a fixed bit framing time slot, on/off, 1/0, +/-,
digital pulses, rectangular shape
Digital Transmition - ✔✔Basic unit of digital information is a bit(binary digit). Old devices use
current flow, new devices change voltage levels
Modem(Modulator/Demodulator) - ✔✔Converts digital into analog, over standard
telephone, converted back into digital
Codec(Coder/Decoder) - ✔✔Convert amplitude changes of various frequencies into digital
format over digital media
EMI(Electromagnetic Interference) types: - ✔✔Radio, Cellular, Transceivers, Lighting, Power
lines, Electric motors, Radar, Electronic ballasts.
, What can reduce EMI? - ✔✔Proper grounding and shielding
Balanced cable(UTP) has - ✔✔same voltage on each conductor in reference to ground
Unbalanced cable(coaxial) has - ✔✔Outer conductor 0V to ground, center conductor at
some voltage carrying the signal
Characteristic impedance can be impacted by - ✔✔Hardware, Design, Installation methods
and procedures
P=VxI - ✔✔Power is equal to Voltage multiplied by current
Resistance is - ✔✔Resistance of a conductor to the flow of electricity through it(Ohms)
Inductance is - ✔✔a property of an electrical force field built around a conductor that
opposes and change in current flow
Inductance is measured in - ✔✔henries(H)
Capacitance is - ✔✔A property of conductors that allows storage of electrical charges when
potential differences exist
Capacitance is measured in - ✔✔farads(micro 1/millionth, nano 1/billionth, pico 1/trillionth)
Impedance is - ✔✔In AC current flow, the total opposition to that current flow(Resistance[R],
Inductance[L], Capacitance[C])
