IT Advanced Operations Lesson 1
Questions with complete solution
Optical line terminal (OLT). - correct answers When converting from HFC and
DOCSIS technology to FTTH, the CMTS is to be replaced with an equivalent
device that is specific to FTTH technology. Which of the following replaces the
CMTS?
DOCSIS - correct answers Made possible for broadband cable operators to
become the largest providers of high-speed data (HSD) service in North
America.
FTTH - correct answers Proven technology that works well for broadband
providers that are replacing their old network infrastructure or building a new
network altogether.
Google Fiber - correct answers First announced in 2010 with the intention to
prove that broadband service could be provided at minimum data rates of 1
gigabit per second (Gbps).
false - correct answers True or False? Splitters, directional couplers, and
service taps are most likely to cause a service outage because of component
failure or loss of power.
Low density parity check (LDPC). - correct answers Which coding scheme is
more efficient at correcting errors and is enabled in DOCSIS 3.1?
Edge quadrature amplitude modulators (EQAM). - correct answers In the M-
CMTS architecture, the physical elements used for downstream RF signal
distribution are separated from the CMTS chassis and the signal is distributed
using which of the following?
