Description
Overview
The Keysight 81571A is a variable optical attenuator module with an angled connector interface, designed for telecommunications and data communication system testing. Optimized for single-mode fiber (9/125 μm SMF28) in the 1200-1700 nm wavelength range, it delivers precise attenuation with excellent optical performance. The angled connector helps minimize back-reflections in test setups.
