Cat5 (Test wanted Cat5e, which contradicts book) |
What is the minimum category of UTP cable required in order to support Gigabit speeds? |
|
MT-RJ |
Which of the following connectors is the most common for multimode fiber? |
|
WDM divides a beam of light into up to 40 different wavelengths or colors |
WDM divides a beam of light into how many different wavelengths or colors? |
|
baseband |
Ethernet is an example of what type of technology? |
|
A type of coaxial cable that is characterized by an impedance of 75 ohms and contains an 18 AWG conducting core. The core is usually made of solid copper. RG-6 coaxial cables are used, for example, to deliver broadband cable Internet service and cable TV, particularly over long distances. |
Which option below reflects the standard impedance of an RG-6 cable? |
|
Modem |
A device that is responsible for modulating digital signals into analog signals, and demodulating analog signals into digital signals at the receiving end, is known as? |
|
WDM (Wanted CWDM, which is Course Wavelength Division Multiplexing) |
Which type of multiplexing is defined by wavelength instead of frequency? |
|
Frequency |
The number of times that a wave’s amplitude cycles from its starting point, through its highest amplitude and its lowest amplitude, and back to its starting point over a fixed period of time, is known as what term below? |
|
DWDM |
The most common multiplexing technology used in conjunction with fiber optics is which option below |
|
Sheath |
What term below is used to describe the outer-most layer of protective covering of a coaxial cable? |
|
True |
Multimode fiber contains a core that is larger than a single mode fiber core. |
|
False (Console Port?) |
A serial cable with an RJ-45 connector is capable of being used through an RJ-45 Ethernet port. |
|
False |
Because digital signals do not depend on amplitude or frequency differences to communicate information, they are more vulnerable to EMI noise. |
|
True |
Digital signals are composed of pulses of precise, positive voltages and zero voltages. |
|
True |
A continuity tester should not be used on a live network segment. |
