Question 86

ITU-T stipulates, what is the switching gain requirement of the Raman amplifier equal to how many DB?

A.8

B.11

C.10

D.9

Question 87

Which of the following are the main reasons why OSC monitoring signals are not amplified by EDFA along with business signals?

A.Prevent monitoring signals from interfering with business signals.

B.The power of OSC is too low, lower than the amplification sensitivity of OA.

C.The rate of OSC is too low, and if it is enlarged, the energy efficiency is too low.

D.Even when the OA fails, the OSC monitoring channel is still valid.

Question 88

During CV/FFD, the ingress node transmits detection packets at a specific interval, and the egress node checks the number and content of these packets at an interval ( ) times the length of the detection packet transmission interval.

C.15

D.3

Question 89

Which of the following operations may interrupt network element services? (Multiple choice)

A.Search protection subnets

B.Disable trails

C.Download network element data

D.Find trails

Question 90

Unlike ROADM, FOADM has some disadvantages. What are the disadvantages of FOAM? (Choose all that apply.)

A.Site visits are required for node capacity expansion and service adjustment.

B.Wavelengths are allocated based on planning. Once they have been allocated, it is difficult to rellocate them, making network flexibility poor.

C.During node capacity expansion, the power budget must be adjusted manually onsite. It cannot be adjusted remotely or automatically.

D.Wavelength services cannot be provisioned quickly.
