Which of the following statements about the latency of a storage and forwarding device is false?

MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.

Dispersion compensation is not required for 40 Gbit/s and 100 Gbit/s coherent systems because the dispersion tolerance of coherent boards is large. NG WDM products do not support hybrid transmission of non-coherent and coherent networks.

Which of the following statements about the modulation technologies of the 40Gbit/s and 100Gbit/s coherent systems are correct?

Which of the following is not a PW APS switching condition?

Loopback is a common operation for routine maintenance and troubleshooting. Which of the following statements about loopback operations are incorrect?

In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. After receiving the OTUk_TIM alarm on the client side, the OTU board at station A sends the OTUk_BDI alarm to the upstream. When the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. The WDM side of the OTU board at station B reports the ODUk_PM_AIS alarm, and the ODUk_PM_AIS alarm is transmitted downstream. The client equipment reports this alarm. After the WDM side of the OTU board at station B receives the OTUk_TIM alarm and the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. After the client side of station B processes the SF event, the client equipment reports the ODUk_PM_AIS alarm.

If tunnel APS is configured for the tunnel to which the PW belongs, PW APS cannot be configured for the PW.

Which of the following methods can be used to analyze faults in the NG WDM system?
