JATC FIBER OPTICS FINAL
OTDRs are used in outside plant cables to _____, _____, and _____. -
ANSWERS-- Verify splice loss
- Measure length
- Find faults in installed cables
What does "OTDR" stand for? - ANSWERS-Optical Time Domain
Reflectometer
Which parameters CANNOT be measured by OTDRs in fiber optic
networks? - ANSWERS-Transmitter and receiver power
The OTDR should never be used without a "launch cable" (aka,
"pulse suppressor"). - ANSWERS-True
Cables tested with an OTDR do not require insertion loss testing with
an OLTS. - ANSWERS-False
The principle of operation of OTDRs is similar to _____. -
ANSWERS-- Radar
Every network needs lots of _____ which may be directly connected
to servers through switches or connected in a "storage area network"
or SAN. - ANSWERS-- Storage
,Wired users and wireless access points are connected to _____ on the
network. - ANSWERS-- Switches
Which network component switches connections between devices on
the network? - ANSWERS-Switches
What type of network architecture consists of all network
devices/users connected to a central point that switches or connects
them to whomever they want to communicate with? - ANSWERS-
Star topology
What type of network architecture utilizes connections that "tap" into
a cable that is usually coax? - ANSWERS-Bus topology
The Internet is an example of what type of network architecture? -
ANSWERS-Mesh topology
Telephone systems and LAN's commonly use ____ networks. -
ANSWERS-- Star
The essence of any network is that the network shares connections
and thereby shares the available _____. - ANSWERS-- Bandwidth
What network device replaced a hub, making full duplex data transfer
possible? - ANSWERS-Switches
, What caused bandwidth to be limited on bus networks when too many
users were using it at the same time? - ANSWERS-Collisions
Fiber optics is used in cars to connect their electronic systems. -
ANSWERS-True
Copper networks can be converted to fiber optics using _____. -
ANSWERS-Media converters
Telephone networks have been converted to fiber, including long
distance and metropolitan networks, but fiber to the home (FTTH) is
