A wavelength-isolating power meter is most commonly used in - CORRECT ANSWER:
Point-to-multipoint FTTx installations.
According to the Federal Communications Commission (FCC) leakage regulations,
what distance must an antenna be from the network for leakage level measurements? -
CORRECT ANSWER: The antenna must be 3 meters (10 feet) from the network
elements and 3 meters (10 feet) above the ground.
Across 6 MHz, what is the maximum in-channel frequency response (ICFR) defined in
the Data Over Cable Service Interface Specification (DOCSIS)? - CORRECT ANSWER:
3.0 dB peak-to-valley (P/V).
Besides RS-232 ports, what type of interface is common on an optical power meter? -
CORRECT ANSWER: A USB interface can provide easy download of information to a
PC.
Chipsets with ingress cancellation algorithms are most effective for removing
impairments in what portion of the RF return frequency spectrum? - CORRECT
ANSWER: Within the upstream channel bandwidth.
Even though the downstream sweep test pulses are intended to fit in the narrow
frequency band between channels, what parameter can cause interference if set too
high? - CORRECT ANSWER: Sweep test pulse amplitude.
, House amplifiers with a passive return path are used for what type of situation? -
CORRECT ANSWER: For situations when long service drops are used and the forward
path needs to be amplified but return path amplification is unnecessary.
How can a distribution amplifier be identified in the network or on a network design
map? - CORRECT ANSWER: The distribution amplifier has multiple downstream
outputs.
How can a less-experienced technician identify what non-standard symbols on the
network design maps represent? - CORRECT ANSWER: The legend at the bottom of
the network design map that defines the map symbols, cable types, and amplifier data.
How can the amount of thermal noise added to a network be minimized? - CORRECT
ANSWER: By ensuring that the RF input is at or above the specified minimum input
level to all amplifiers.
How does surge protection at the input and output of a ferroresonant power supply
defend against voltage surges? - CORRECT ANSWER: By passing voltage surges
(within the surge device rating) to ground without damage.
How does the signal attenuation through coaxial cable in the sub-band frequency
spectrum compare to the attenuation at forward path frequencies? - CORRECT
ANSWER: At sub-band frequencies, the signal attenuation is significantly less than in
the forward path.
How has the optical power meter changed? - CORRECT ANSWER: Enhanced power
meters evolved where more complex records are required, and measurements need to
be easily stored, recalled, transmitted, and downloaded.
How is impulse noise characterized when viewed on a spectrum analyzer? - CORRECT
ANSWER: Impulse noise will appear as random spikes of energy across the entire
return path frequency spectrum (5 to 42 MHz).
