Question

QUESTION 29

When considering the quality of laser light sources, a narrower spectral width is preferred.

True

False

QUESTION 30

Select the difference(s) between optical LED and LD light sources.

a. LED light sources are slower than LDs

b. LEDs produce incoherent light, compared to LDs which produce coherent light

c. LDs have a more narrow spectral width compared to LEDs

d. All of the above are differences between LEDs and LDs

QUESTION 31

APD (Avalanche Photo Diode) light detectors amplify optical signals during the optical-to-electron (OEO) conversion. PIN (Positive Intrinsic Negative) light detectors do not amplify the optical signal during the OEO process.

True

False

QUESTION 32

The use of optical amplifiers, such as the EDFA (Erbium-Doped Fiber Amplifier) and Raman Amplification, do not require conversion from optical to electrical signals during the amplification process.

True

False

a. LED light sources are slower than LDs

b. LEDs produce incoherent light, compared to LDs which produce coherent light

c. LDs have a more narrow spectral width compared to LEDs

d. All of the above are differences between LEDs and LDs

Explanation / Answer

QUESTION 29 - When considering the quality of laser light sources, a narrower spectral width is preferred

TRUE

QUESTION 30 - Select the difference(s) between optical LED and LD light sources.

QUESTION 31 - APD (Avalanche Photo Diode) light detectors amplify optical signals during the optical-to-electron (OEO) conversion. PIN (Positive Intrinsic Negative) light detectors do not amplify the optical signal during the OEO proces

FALSE

QUESTION 32 - The use of optical amplifiers, such as the EDFA (Erbium-Doped Fiber Amplifier) and Raman Amplification, do not require conversion from optical to electrical signals during the amplification process.

TRUE (An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal)
