Questions & ANSWERS(RATED A)
T/F The biggest advantage of optical fiber is the fact it is the most cost effective means of transporting
information. - ANSWER True
Fiber can transport more information longer distances in less time than any other communications
medium,
_______ companies "overbuild with fiber, often lashing fiber optic cables to installed aerial coax cable. -
ANSWER CATV
Copper networks can be converted to fiber optics easily using: - ANSWER Media converters
The bandwidth and distance capability of optical fiber means that _________. - ANSWER Fewer cables
are needed, Fewer repeaters are needed, Less power is consumed by the network, Less maintenance is
required
T/F Telephone networks have been converted to fiber, including long distance and metropolitan
networks, but fiber to the home (FTTH) is not yet feasible. - ANSWER False
FTTH is cost effective today because of the demand for high speed digital services in the home and the
development of lower cost PON networks.
Today, with the exception of some _________, the entire telephone backbone is fiber optics. - ANSWER
Some rural or remote locations
Around the world use satellites instead of fiber to reach distant users.
Which Networks use fiber optic backbones? - ANSWER Telephones, CATV, Internet, Cell Phones
