QUESTION 25
For guided conductive mediums such as UTP (unshielded twisted pair) and coaxial cable, thicker conductors (i.e., lower AWG numbers) result in higher data rate capacities being supported.
True
False
QUESTION 26
Select the correct statement(s) regarding UTP.
| a. UTP signals are balanced, meaning that one wire transmits the signal, while the other wire is connected to ground
| |
| b. All UTP wire pairs within a cable (e.g., Cat 5e) are twisted at exactly the same twist ratio
| |
| c. UTP signals are balance, which means that each wire within a pair carries the same signal, but with opposite polarities
| |
| d. Crosstalk is never a problem with UTP
|
QUESTION 27
Coaxial conductors use unbalanced signals, which means that it is less capable than UTP balanced conductors with regards to data rate capacity and attenuation.
True
False
QUESTION 28
Select the correct statement(s) regarding fiber optic cable.
| a. The core and cladding within a fiber optic cable must have the same refractive index in order to achieve TIR (Total Internal Reflection)
| |
| b. Only single mode fiber (SMF) can be constructed with either a step or graded index core
| |
| c. Mulimode optical fibers (MMF) are vulnerable to modal dispersion
| |
| d. All statements are correct
