Which of the following alarms will be reported when performing a fiber cutting test on a normal MSP ring? (Multiple choice)
- A . TU-AlS
- B . R-Los
- C . APSJNDI
- D . BD status
Which of the following descriptions of ODUk SNCP protection type is wrong?
- A . When the protection subtype is "SNC/I, there is no need to set the OTN overhead. However, when configuring this type of protection, both ends of the service must be within the range of SM overhead monitoring;
- B . The protection subtype is "SNC/S": monitors the PM layer and needs to set the OTN overhead;
- C . For boards that require ODUk SNCP protection and electrical cross-connection, the configuration varies depending on the selected board and customer-side services;
- D . The ODUk SNCP protection configuration of the receiving site needs to be consistent with the ODUk SNCP protection configuration of the sending site;
The length of Ethernet frames has a lower limit. What is the main consideration?
- A . Carrier Sense
- B . Multi-point access
- C . Conflict Detection
- D . Improve network bandwidth utilization
As shown in the figure, which of the following wavelengths is used for FD fiber mass star detection from station A to station B?
- A . 1510 nm
- B . 1310nm
- C . 1401nm
The maximum dispersion tolerance of an OTU board is 800ps/nm. On a G.652 fiber, the dispersion-limited distance can be roughly considered to be?
- A . 40KM
- B . 60KM
- C . 80KM
- D . 10KM
Which of the following is a time slot optimization step? (Multiple choice)
- A . Before optimizing the time slot, clean up the services, delete the junk services, and confirm with the customer to complete or delete and rebuild the defective services.
- B . Data collection and production optimization plan: It requires consistency verification of customer network metadata, fiber cable connection, and full network path data: and handles deactivation services in the network and confirms unidirectional services in the network.
- C . Analyze resource assessment reports, focus on low-order cross-connect resources and line time slot utilization, pay attention to bottleneck locations, and confirm the principles of routing time slot optimization with customers
- D . Generate a time slot optimization plan in AMS5000 based on the optimization principles and write an implementation plan.
OptiX OSN 1800 is a compact multi-service optical transport platform. Which of the following descriptions is wrong?
- A . Does not support 158802 transmission and does not support external time signal access
- B . Single channel maximum rate 10Gbit/s (OTU2)
- C . The OptiX OSN 18001 chassis provides a total of 4 service board slots
- D . The OptiX OSN 180011 chassis provides a total of 8 service board slots
A network is configured with SOM. When performing path performance analysis, the OSNR value of the downstream optical amplifier in the OCh path is higher than that of the upstream optical amplifier. Which of the following analysis is wrong?
- A . After the initial configuration of the SOM route is issued, the performance analysis is started immediately. If the SOM route is configured in the OMS segment at this time, and the OSNR calculation is started first, there is no OSNR calculation value in the previous segment as a basis, this phenomenon will occur.
- B . The OSNR value calculation of the first part of the OMS segment where the OCH path is located has been completed, but the calculation of the second part has not yet started. At this time, the performance analysis is started. Due to external reasons, the newly calculated value of the first part is reduced, which will cause this phenomenon
- C . The network management sends the SOM routing configuration to the OMS segment on the path from the front to the back. It takes about a few seconds for each OMS segment to send the SOM routing configuration. There is a time difference in configuring the SOM routing between each OMS segment .
- D . Click "Analyze" on the "Path Performance Analysis" interface to restart the performance analysis to solve this problem.
Which of the following is not one of the possible reasons for the CPW_OMS_TEL_DOWN alarm?
- A . Fiber misconnection
- B . The OMS TE link LMP protocol is not enabled
- C . There is no available control channel between the nodes at both ends of the OMS TE link
- D . Circuit board failure
The tunnel-level APS protection of Hybrid MSTP equipment can support forced switching and locked switching, and the priority of forced switching is higher than that of locked switching.
- A . True
- B . False
