NEW QUESTION 75
AGC can solve a multi-wavelength WDM system. When some wavelength signals are lost, due to gain competition, its energy will be transferred to those signals that are not lost, making the power of other wavelengths higher.

True

False

NEW QUESTION 76
Corresponds to the ISO seven-layer model. Ethernet corresponds to the physical layer and network layer of the seven-layer model, and the specifications defined by Ethernet include the MAC sublayer and the physical layer of the data link layer.

True

False

NEW QUESTION 77
Most of the WDM systems on the existing network adopt the single-fiber bidirectional transmission mode.

True

False

NEW QUESTION 78
Which of the following paths can be configured on the network management? (Multiple choice)

Client

ODUk

OTS

OCh

NEW QUESTION 79

NEW QUESTION 80
Which of the following monitoring boards does not support the processing and transparent transmission of 1588V2 signals? (Multiple choice)

ST2

SC2

SC1

AST2

NEW QUESTION 81
For a 10G OTU board, the optical module at the receiving end uses a PIN module, so which of the following receiving powers is within the normal receiving range of the board?

-9dBm

-19dBm

9dBm

19dBm

NEW QUESTION 82
Since different frequency (or wavelength) components of the light source have different group velocities, in the transmission process, the time delay of different frequency beams is different and the dispersion is called ()

Chromatic dispersion

NEW QUESTION 83
Which of the following descriptions about the ROADM board is correct? (Multiple choice)

The TM20 board supports adding 20 coherent optical signals of different wavelengths and multiplexing them into 1 multiplexed optical signal to realize the colorless adding function.

RDU9 implements the broadcast function of the main optical channel signal in 9 directions at the same time.

The TD20 board supports broadcasting output of a coherent service signal containing 20 different wavelengths at the same time. Since the coherent OTU or line board has the wavelength selection function, it can realize the colorless downwave function of 20 waves.

The RMU9 board completes the adding function of 8 channels of single-wavelength or multiplexed-wavelength optical signals.

NEW QUESTION 84
The TOA board is an 8-way arbitrary rate service tributary processing board. Which of the following description about the TOA (STND) board is wrong?

The maximum crossover capacity of a TOA board is 20 Gbit/s

When the service on the client side is GE, the working mode of the port is ODU0 non-aggregation mode, and the intra-board crossover needs to be configured.

When the client-side service is STM-16, the port working mode is ODU1 non-aggregation mode, and there is no need to configure intra-board crossover

When the service on the client side is FE, the working mode of the port is ODU1 aggregation mode, and the intra-board crossover needs to be configured.

NEW QUESTION 85
Which of the following are the ways to back up the network element database? (Multiple choice)

Back up the NE database to the CF card

Back up the network element database to the main control board

Backup network element data to the network management client

Backup network element data to the network management server

NEW QUESTION 86
The technology of recovering amplitude, phase and polarization state information from the received signal by using which of the following characteristics of the laser to coherent with the received optical signal is called coherent receiving technology?

Vibration in the same direction

Same amplitude

The direction of vibration is opposite

same frequency

NEW QUESTION 87
When using a script to back up U2000 data, the backup speed is very fast because the backup file is small.

True

False

NEW QUESTION 88
Which of the following clock operating modes supports the ITU-TG781 standard? (Multiple choice)

Tracking

Keep

Run free

Master/slave

NEW QUESTION 89
When LCK is inserted at the local ODUk PM overhead, how does the downstream site process the insertion?

Inserts the ODUk PM BDI alarm back to the upstream site.

Continues to transparently transmit the ODUk_PM_LCK alarm to the downstream site.

Inserts the ODUk_PM_LCK alarm back to the upstream site.

Reports the ODUk_PM_LCK alarm.

When LCK (Lock) is inserted in the local ODUk PM overhead, the downstream site processes it by (A) inserting the ODUk PM BDI (Backward Defect Indication) alarm back to the upstream site and (D) reporting the ODUk_PM_LCK alarm locally. This mechanism allows upstream devices to be aware of downstream lock conditions, enabling coordinated protection actions. HCIP-Transmission highlights these procedures as part of OTN fault propagation and monitoring to maintain network stability and rapid fault response.
