정답: B
The alarm detection of the optical layer overhead is realized through the optical layer overhead OOS. Although the alarms such as R_LOS and MUT_Los are also optical layer alarms, they are not based on OOS detection and reporting, but based on optical power detection and reporting.
정답: A
When light passes through a passive optical device, it will cause a drop in optical power. This loss is called the insertion loss of the device.
정답: A
The OTS path refers to the physical fiber connection between two adjacent OM/OD/OA on the main optical path.
정답: B
Some SNCP protection switching conditions are default. For example, AUAIS and TUAS. Other conditions are optional. For example, HP-TIM and HP-SLM. Optional conditions can be flexibly set according to the service level.
