Figure 5. OPTICAL LOSS TEST SET Screen.
The display is divided into three equal rows. Each row shows measurements for
each wavelenght. Next are described each one of the fields on screen:
The SIGNAL LED indicates the status of the signal with respect to the
threshold values. Three indicator lights colours are possible and each
colour represents status signal with respect to threshold values: GREEN
(PASS), AMBER (HIGH) and RED (LOW).
Wavelenght at which it is measuring. Wavelenght at 1310 nm corresponds
to the UPSTREAM and the other two (1490 y 1550 nm) to the
DOWNSTREAM.
Signal status with respect to threshold values. Three status are possible:
PASS, HIGH, LOW.
Power graphical representation.
Lower threshold value.
Upper threshold value.
Group of threshold values selected. Threshold values can be grouped and
saved on the memory of the instrument and later to select the one that
best meets the criterion of quality to follow.
Relative losses of the signal with respect to the reference value. Reference
value can be changed by capturing a new one.
Absolute signal losses at the corresponding wavelenght. It represents the
losses power of the signal in dB.
