Features:

• Measurement accuracy of ±2.5% is guaranteed under the reference conditions
• Covers a wide waveband from 400 to 1870nm, and provides a dynamic range of 100dB or more for loss measurement (It depends on sensors)
• The AQ2733 and AQ2734 sensor units achieve a low polarization dependence of 0.02dBp-p or less
• The AQ2734 sensor unit uses a photodiode with flat wavelength sensitivity from 1300 to 1800nm, for accurate measurement at 1650nm as well
• 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
• The internal high-stability sensor can be used together with the LD unit to provide stable reflectance attenuation measurement
• 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
• A wide variety of optical connectors can be used just by exchanging the universal connector adapters (AQ4214 excluded)
• Optical power can be decreased in 0.1 dB steps to 6.0dB
• The LD unit has an internal isolator that maintains optical output level stability at ±0.003dB
