M402D can realize the wavelength division side optical signal in the extended C band 50GHz interval
96 wavelength range domestically adjustable

Support ODUk SNCP protection and client side 1+1 protection

Dual-channel 100 Gbit/s wavelength conversion board

QUESTION 428
Are the following statements regarding the definition of SDH correct?

hierarchy that can be used for asynchronous digital transfers

A hierarchy of standardized digital signals that can be asynchronously reused

A hierarchy of standardized digital signals that can be cross-connected asynchronously

Complete hierarchy of standard mathematical signals, providing simultaneous digital transmission multiplexing and cross-connectivity

QUESTION 429
Which of the following options are correct? (Multiple choice)

SATop encapsulation type processes CES services by packaging the 32 time slots in the E1 frame as a whole and then transparently transmitting them to the other end.

The CESoPSN protocol can identify the structure of TDMN services. It does not need to transmit idle time slot channels. It only extracts useful time slots from the service flow and encapsulates them into PWE3 messages for transmission.

PCM30 frame format of E1 frame: except time slot 0 which is used as synchronization time slot and does not carry voice, time slot 16 also cannot carry voice because it is used to transmit random signaling.

PCM31 frame format of E1 frame: except for 16 time slots as synchronization time slots that do not carry voice, it can also carry 31 channels of voice.

QUESTION 430
Which of the following operations may interrupt network element services? (Multiple choice)

Search for protected subnets

Finding a trail

Out of use trails

Download network data

QUESTION 433
For Huawei equipment, NODE ID is the unique identifier of the intelligent network element in the control plane. After the network is configured with intelligent services, the NODE ID will no longer be modified during construction.

True

False

QUESTION 434
When performing fiber cut-off test on an ordinary MSP ring, which of the following alarms will be reported? (Multiple choice).

YOU-AIS

R-LOS

APSJNDl

QUESTION 435
Regarding the comparison between Raman amplifier and EDFA, which of the following statements is wrong?

Raman amplifiers can amplify signals of different bands by selecting different pump sources, so Raman amplifiers theoretically have no gain bandwidth limitation, while EDFA has a limited gain bandwidth.

The gain calculation/test method of Raman amplifier and EDFA is the same, both are “Gain = Output Power – Input Power”

The gain medium of the Raman amplifier is the transmission fiber; while the gain medium of the EDFA is EDF (doped fiber) D. The equivalent noise index of the Raman amplifier is smaller than that of the EDFA

QUESTION 436
Which of the following modulation technologies has the best performance in terms of wavelength stability?

Indirect modulation

Direct modulation

M-Z modulation

EA modulation

True

False

QUESTION 438
If bit errors occur in the SDH network, the service signal restored after decapsulation will definitely contain bit errors.

True

False

QUESTION 439
Which of the following options are included in the alarm level in the NCE-T system? (Multiple choice)

Minor alarm

Prompt warning

Important warning

Emergency Alert

QUESTION 440
PDH is a quasi-synchronous digital system, which also belongs to the synchronous digital transmission system.

True

False
