Condition: used
1. Sensor, 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.

2. Light source unit:
?High stability--The LD unit has an internal isolator that maintain
optical output level stability at ±0.003dB.
?Optical power attenuation function--Optical power can be decreased in 0.1dB steps to 6.0dB.
?Support for a variety of connectors--A wide variety of optical connectors can be used just be exchanging the universal and connector adapters (AQ4214 excluded).

3. 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 LD unit, the display will show reflectance attenuation after measurement of reference reflectance by merely disconnecting the measured fiber cable.
