問題 #39
How does a Raman pump work in the 1830 specific implementation?

A. The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.
B. The amplification is done simultaneously for all channels as they enter the board.
C. The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.
D. As the incoming signal power increase, the gain of the amplifier is reduced.

答案：A

解題說明：
In Raman amplification, a pump laser is used to excite the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. In the 1830 specific implementation, the pump laser is typically a high-power laser that is launched into the fiber in the opposite direction to the signal. The pump light interacts with the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. This allows the Raman pump to provide a gain that increases with distance, which can be used to compensate for the loss of signal power as it travels through the fiber.

問題 #40
Which of the following are the main reasons for fiber attenuation?

A. Scattering and absorption
B. Refraction and reflection
C. Small channel spacing
D. Chromatic dispersion (CD) and polarization mode dispersion

答案：A

解題說明：
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.

問題 #41
In which window(s) does the attenuation reach its minimum peak?

A. Both first and second windows
B. First window (850 nm)
C. Third window (1550 nm)
D. Second window (1300 nm)

答案：C

解題說明：
The third window (1550 nm) is where the attenuation reaches its minimum peak. This is because the materials used in fiber optic cables have minimal absorption in this wavelength range. The first and second windows (850 nm and 1300 nm respectively) have higher attenuation due to the materials used in the fiber optic cables.

問題 #42
A user needs to check for interface details against the commands is the correct one?

A. 11starla 1/17 port-detail
B. config card 11star1a interface 1/17 detail
C. config interface detail 1/17/L1
D. show interface 11starla 1/17/L1 detail

答案：D

解題說明：
show interface 11starla 1/17/L1 detail is the correct command to check for interface details. This command will display detailed information about the specified interface, including its status, configuration, and statistics.

問題 #43
What is the definition of OSNR?

A. The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.
B. The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber including both signal and optical noise.
C. The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.
D. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.

答案：A

解題說明：
The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth. This is also known as the signal-to-noise ratio (SNR), and it is a measure of how much signal is present in the optical signal compared to the noise, usually expressed in decibels (dB).
