Fiber-optic cable networks can span much longer distances than copper-based networks before requiring repeaters because:
[x]they use wavelength division multiplexing.
[ ]their signals never require amplification.
[ ]they are resistant to noise such as EMI.
[ ]their signals do not suffer degradation no matter how small the cable's bend radius.
A form of transmission in which signals are modulated as radio frequency (RF) analog waves that use different frequency ranges.
In modulation, a simple wave called a(n) ____ wave, is combined with another analog signal to produce a unique signal that gets transmitted from one node to another.
The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length.
The serial interface on the back of the connectivity device is often labeled "____."
Technology used to modify analog signals to make them suitable for carrying data over a communication path.
You are helping to install a cable broadband system in your friend's home. She wants to bring the signal from where the service provider's cable enters the house to a room on another floor, which means you have to attach a new cable to the existing one. What type of cable should this be?
The data transmission characteristic most frequently discussed and analyzed by networking professionals is ____.
Latency occurs when a signal traveling on one wire or cable infringes on the signal traveling over an adjacent wire or cable.
____ is a technology used with fiber-optic cable, which enables one fiber-optic connection to carry multiple light signals simultaneously.
WDM (wavelength division multiplexing)
