A.The total loss of the fiber will affect the actual detection distance. The dynamic range of the same detection mode is fixed. The larger the total loss of the fiber, the smaller the distance that can be detected.

B.Different modes of light pulse width are different in detection, pulse width affects distance accuracy and monitoring distance. The larger the pulse width, the larger the dynamic range, the longer the test distance and the higher the range measurement accuracy.

C.Line fiber quality monitoring function increases the monitoring accuracy by adding the averaged results to the average. The actual time required from the start detection to the software returning the test result will be greater than the "detection time" is set.

D.Increasing the pulse width increases the duration of the laser emission, which increases the energy injected, allowing for a larger dynamic range, but an increase in pulse width results in a larger dead zone.

A.CLASS 1M means low optical power, no damage to eyes or skin

B.Regularly clean the air filter to facilitate heat dissipation

C.Equipment needs safety grounding

D.Wear an ESD-preventive wrist strap or gloves to prevent static electricity from damaging the board.

A.The PM_BIP8_SD alarm indicates the PM segment signal degradation alarm in the ODU layer.

B.The PM_BIP8_OVER alarm indicates the PM segment error amount of the ODU layer is over-limit alarm.

C.The PM_BIP8_DEG alarm indicates the PM segment signal degradation alarm in the ODU layer.

A.TRUE
