You want to measure the voltage, amps, and ohms of various devices. What tool would you use?
- ✔✔You'd use a multi-meter.
what's a multimeter? - ✔✔a device for testing various electrical properties. i.e. ac/dc voltage,
current (amps), resistance (ohms), capacitance, and frequency.
What does a voltage event recorder do? - ✔✔keeps track of voltage conditions on a power line.
basic recorders simply keep track of the occurrence of under/over voltage conditions, while more
advanced devices track conditions over time/create a graph, saving data from a program running
on a computer.
What's a butt set also called? - ✔✔a lineman's handset.
what is a butt set used for? what does it include? - ✔✔testing analog telephone installations.
includes: an earpiece, mouthpiece, dialing interface, and various connectors.
What is a toner probe, and what is it used for? - ✔✔a toner probe is 2 devices used together to
trace the end of a wire from a known endpoint into the termination pt in the wiring closet.
what is a cable certifier? - ✔✔a cable certifier is a multi-function tool that verifies or validates
that a cable or an installation meets the requirements for a specific architecture implementation.
i.e. use a certifier to verify that a specific drop cable meets the specs for 1000BaseT networking.
which of the following is true about single mode fiber optic network cabling? - ✔✔the central
core is smaller than that of multi-mode fiber optic cabling.
How does a single mode fiber optic cable transmit data (and through what)? does single mode
support longer or smaller transmission distances? - ✔✔By transmitting a single ray (or mode) of
light through glass or plastic fiber. supports longer transmission distances than multi-mode fiber
optic cable & is also more expensive. also has a central core that is much smaller than that of
multi-mode fiber optic cabling.
how do msgs travel through a logical ring topology based network? - ✔✔msgs travel from one
device to the next until they reach the destination device. basically, in a logical ring topology;
msgs travel to each device in turn. if the msg isn't intended for that device, the msg is forwarded
to the next device on the network.
name two fiber optic connectors that usually require polishing as part of an assembly process? -
✔✔SC & ST connectors.
fiber optic cable assembly is more complex than other assemblies. it's necessary to polish the
exposed fiber tip to ensure that ligh
