Agilent 81577A The Agilent variable optical attenuator family features lowest insertion loss and
excellent wavelength flatness over a complete attenuation range of 60 dB, for characterizing
optical network components for telecomunication and data communication in systems.
The power control feature in the Agilent’s variable optical attenuator module (81577A) enables the
user to set the output power level of the attenuator. The model of ’attenuator plus power meter’
eliminates measurement uncertainty of various instruments and optical components such as optical
coupler in one system because the Agilent’s test instrument provides complete specification in one
module. It is ideal solution for test setup with BERT (bit error rate tester) or DCA (digital
communication analyzer) where various power levels need to be precisely tested. High Input
