The Keysight (Agilent) 8156A is a precision optical attenuator designed for both single-mode and multimode fiber applications, operating across 1200 nm to 1650 nm. It features a 60 dB attenuation range with an ultra-fine 0.001 dB resolution and employs a single-filter design that eliminates ranging, dark spots, and overshoots. Typical performance includes ±0.05 dB linearity, ±0.005 dB repeatability, and <0.02 dB polarization-dependent loss, with up to +23 dBm input power. The attenuator delivers 60 dB return loss and is available in multiple configurations including built-in monitor outputs and options for different connector types and return loss levels (35 dB to 60 dB).
Ideal for precise optical signal control in telecom, R&D, and fiber testing environments, the 8156A ensures stable, repeatable attenuation with minimal signal distortion.
