Optical Pulse Measurement (OTDR)

2.2 Performing Averaged Measurements
WARNING
• During measurement, light is transmitted from the light source ports. Do not disconnect the
connected optical fiber cables. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. Visual impairment may occur if light that is mistakenly emitted from these ports
enters the eye.

AVERTISSEMENT
• Lorsque l’AQ7280 génère de la lumière, la lumière est émise à travers les ports de source
lumineuse. Ne pas débrancher les câbles de fibre optique connectés. Des lésions oculaires
peuvent être causées si le faisceau lumineux pénètre l’œil.
• Couvrir les caches des ports de source lumineuse libres. Sur les modèles dotés de deux
ports de source lumineuse ou plus, protéger les yeux contre l’émission accidentelle de
lumière depuis le mauvais port.
In averaged measurements, the data that is acquired from each pulse is averaged and displayed. By
performing averaged measurements, you can improve the signal-to-noise (S/N) ratio.
This is effective when you want to detect faint events that are buried in noise.
Procedure
Starting and Stopping Measurements
1.
From the top menu, select OTDR.
2.
Press AVG. The measurement begins, and the measurement waveform is displayed on the
screen.
The Average menu appears. The average duration or progress is displayed in the top area of the screen.
Also, during measurement, a mark appears at the top of the display to indicate that the laser light is on.
