CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+
Monitoring the status of optical nodes - ANSWER>>Involves the
use of a node transponder that continuously monitors a number of
critical functions.
Digital return path transmissions - ANSWER>>Use DWDM
Dense wavelength division multiplexing
digital return transmitters in hub-to-headend architectures.
Broadband cable operators provide customers with HSD High-
speed data connections to the Internet via their HFC networks
using what standard? - ANSWER>>DOCSIS
What is MPEG? - ANSWER>>A universally accepted standard for
digital television, first released in 1992.
Which of the following is true about optical nodes? -
ANSWER>>They contain four main sections: the optical receiver,
the RF amplifier module, the reverse optical transmitter, and the
DC power supply.
What product based on the DOCSIS defines the protocols for IP
telephony over HFC? - ANSWER>>PacketCable
In a centralized server VOD architecture, - ANSWER>>The
number of servers needed for video content storage is smaller
than in the distributed server architecture.
, Which of the following statements about local ad insertion is true?
- ANSWER>>Local ad insertion is performed usually by a video
server.
In regard to providing HSD service, - ANSWER>>The CMTS
Cable modem termination system
can provide a data transfer rate up to 38 Mbps, using 256-QAM
in a single 6 MHz channel.
Which of the following is true about the SONET standard? -
ANSWER>>SONET is the North American standard used for
telephony applications.
Compared to a solid copper center conductor, which property
about a copper clad aluminum (CCA) center conductor is correct?
- ANSWER>>The CCA center conductor has almost equal
attenuation at high frequencies.
In hardline coaxial cable, what is the most common dielectric
material? - ANSWER>>Foamed polyethylene produced by gas
injection.
In aerial installations, why do cable manufacturers recommend
that expansion loops be formed in hardline coaxial cable? -
ANSWER>>To allow movement of the cable when lashed to the
strand
Why was the impedance for the broadband cable industry
standardized at 75 ohms (Ω)? - ANSWER>>At 75 Ω characteristic
impedance, the coaxial cable has minimal attenuation, with
adequate breakdown voltage and power carrying capacity.
What is the coaxial cable velocity of propagation (VoP)? -
ANSWER>>The rate that radio frequency (RF) signals travel
