A. The maximum difference of insertion loss between M40 and M40V channels does not exceed 3dB
B. M40 channel insertion loss≤6.5db
C. Insertion loss between TI-TO1 on OLP board≤1.5dB
D. M40V channel insertion loss≤6.5dB
E. LINE1-SYS1 insertion loss of SFIU≤1.0dB
F. OLP board RI1-RO insertion loss ≤1.5dB

Question 2

When configuring the Ethernet service, the value of the J1 byte in the higher-order channel overhead should be the same as the value that should be received, but the Ethernet single board EGT2 and EFS0 both generate the HP_TIM alarm. C

A. Light path failure
B. The mode set by the J1 byte is inconsistent
C. EGT2 and EFS0 protocol are inconsistent
D. EGT2 and EFS0 cannot be connected

Question 3

When the MR1 board is used as an OSN1800 single fiber bidirectional in the following scenarios, you can use the MR2 or MR4 board instead

A. TRUE
B. FALSE

Question 4

The C-band 40-wave system is transformed into a C-band 80-wave system. The correct description is (multiple choice)

A. The original business signal-to-noise ratio remains unchanged after operation
B. Unprotected networking operation process will interrupt the original business
C. There is no change in the optical power of the OTU WDM side
D. Need to re-adjust the light emission power

Question 5

A certain network is configured with SOM. When performing path performance analysis, the OSNR value of the downstream optical amplifier of the OCh path is higher than that of the upstream optical amplifier. What is the error of the following analysis ()?

A. After the initial configuration of the SOM route is issued, the performance analysis is started immediately. If the SOM route is configured first in the OMS section at this time, the OSNR calculation is started first, and there is no basis for the previous OSNR calculation value, this phenomenon will occur
B. The network management must issue the SOM routing configuration to the OMS segment on the path in order from the front to the back. It takes about a few seconds to issue the SOM routing configuration for each OMS segment, and it takes a few seconds to configure the SOM routing existence time between each OMS segment. difference
C. Click "Analyze" on the "Path Performance Analysis" interface to restart the performance analysis to solve the problem
D. The calculation of the OSNR value of the first part of the OMS section where the OCH path is located is completed, and the calculation of the latter part has not been started. At this time, the performance analysis is started, and the new calculated value of the front part is reduced due to external reasons. This phenomenon will occur
