NEW QUESTION 50
The EDFA in the OAU board has a gain lock function. When the optical signal of one or several channels or some channels fluctuates, it does not affect the signal gain of other channels.

TRUE

FALSE

NEW QUESTION 51
What should be paid attention to when planning a 1588V2 network?

It is recommended to adopt BC mode for the whole network in the networking mode

In practical applications, there may be a distance difference between the two directions of the fiber optic transceiver, but there is no need to compensate for this. 1588V2 will automatically calculate it according to the algorithm

BMC algorithm must be activated to prevent looping

1PPS + TOD interface is more suitable for internal transmission of the network

NEW QUESTION 52
The function of PW OAM is basically the same as that of Tunnel. The PW OAM mechanism can effectively detect, confirm and locate defects and faults originating from the PW layer network.
Which of the following functions are not available in PW OAM?

Ping

BDI

FDI

NEW QUESTION 53
After the faulty board is found at the beginning of the project, after calling the TAC phone to locate the fault, you can go through the DOA process and apply for spare parts directly

TRUE

FALSE

NEW QUESTION 54
Regarding the OSNR test of the OTN system, which of the following statements is correct? () (multiple choice)

When using OSA to test OSNR, because the noise in the signal band cannot be directly tested, the out-of-band noise interpolation method is adopted to calculate the noise in the band

The out-of-band noise interpolation method refers to inserting the noise of the instrument to replace the actual noise of the system

After the wavelength signal passes through a filter device such as D40, the noise power between channels will be reduced, so the OSNR value of the traditional OSA test is higher

The 40G and 100G wavelengths overlap due to the signal spectrum, and the OSNR value tested by the traditional OSA test method is low

The integral method test OSNR is also called the turn-off method, and the channel business will be interrupted during the test. And in the case of a small number of waves, the OSNR value measured by the integral method has a certain deviation from the true value

OptiX OSN8800/6800 equipment MCA online test 100G wavelength OSNR also uses the shutdown method

NEW QUESTION 55
For NG-SDH equipment equipped with dual main control, when the main control board is upgraded, which of the following statements is correct?

After the backup main control board has been upgraded first, the original main control can be upgraded only by switching between the main and the backup.

Directly upgrade the main control board first, and then upgrade the standby main control board

First complete the upgrade of the standby main control board, and then perform a hard reset on the current active main control board to switch between the main and standby main control boards, and then upgrade the current standby main control board

Upgrade the main main control board first, and then upgrade the standby main control board in the same way

NEW QUESTION 56
The main difference between SNCP and PP ring is that SNCP adopts tributary board selective reception while PP adopts cross board selective reception.

TRUE

FALSE

NEW QUESTION 57
The reason for reporting the BEFFEC_EXC alarm is that the following statement is wrong

The signal has too much loss in line transmission.

The input optical power of the OTU board is too high or too low

This alarm will not be reported in AFEC mode.

The FEC mode settings of the OTU at both ends are incorrect.

NEW QUESTION 58
During the degrading process of the smart business, the intermediate node is reset, and the downstream node will have

Residual signaling

Time slot reserved residue

Time slot inconsistency remains

NEW QUESTION 59
When board services such as LOA/TOA/THA/TOM/TOG are activated, the local client-side interface reports the L_SYNC alarm. The cause is

Abnormal light reception on the client side interface of the local end, abnormal light reception on the client side interface of the opposite end

The client-side interface of the local end receives normal light, but the client-side interface of the opposite end receives abnormal light.

The client-side interface at the local end receives normal light, and the client-side interface at the opposite end receives normal light

The light reception of the client-side interface of the local end is abnormal, and the light reception of the client-side interface of the opposite end is normal.

NEW QUESTION 60
The WDM optical layer ASON DCC D4-D12 setting pass-through has no effect on ASON

TRUE

FALSE

NEW QUESTION 61
The main survey points of engineering survey are (multiple choices)

Length of optical fiber, interface type

The diameter, length, number of power supply circuits, power supply voltage, power supply power of the power cord

Computer room installation environment such as the height of the computer room, wiring method, ground type, load-bearing capacity of the computer room, seismic requirements, row spacing, etc.

Impedance, wire diameter, length, and connector of the relay cable

NEW QUESTION 62
After the OTN device to the storage device is opened, the actual service rate is less than 20% of the interface rate. Possible reasons (multiple choice)

The FClicense configuration of the storage switch is incorrect

There is a problem with the docking optical power

Interface rate does not match

The remote function is not enabled on the docking port of the transmission device

NEW QUESTION 63
When deploying QoS, where the complex classification of data flows is usually deployed in the network

Edge access layer

Convergence layer

Core layer

NEW QUESTION 64
Designed as a C-band 80-wave system, add the operation of the C-band odd-numbered wave, the description is correct (multiple choice)

Need to re-adjust the light emission power

The original business signal-to-noise ratio remains unchanged after operation

The operation process will interrupt the original business

There is no change in the optical power of the OTU WDM side
