Sensor
Unit
High Accuracy
Measurement accuracy of ±2.5% is guaranteed under the reference
conditions.
Wide wavelength range and dynamic range
Covers a wide waveband from 400 to 1870nm, and provides a dynamic
range of 100dB or more for loss measurement.
(It depends on sensors.)
Low polarization dependence
The AQ2733 and AQ2734 sensor units achieve a low polarization dependence
of 0.02dBp-p or less.
Support for the 1650nm band
The AQ2734 sensor unit uses a photodiode with flat wavelength sensitivity
from 1300 to 1800nm, for accurate measurement at 1650nm as well.

Light
source unit
High
stability
The LD unit has an internal isolator that maintains optical output
level stability
at ±0.003dB.
Optical power attenuation function
Optical power can be decreased in 0.1 dB steps to 6.0dB.
Support for a variety of connectors
A wide variety of optical connectors can be used just by exchanging
the universal connector adapters (AQ4214 excluded).
Return
Loss unit
High accuracy
Because internal self-reflectance data is stored by individual units
in memory to correct operations, even high-reflectance attenuation
can be measured with excellent accuracy.
High stability
The internal high-stability sensor can be used together with the
LD unit to provide stable reflectance attenuation measurement.
Simple operation
Mounted with a return loss unit and an LD unit, the display will
show reflectance attenuation after measurement of reference reflectance
by merely connecting the measured fiber cable.
