Variable Optical Attenuator Module 1250nm - 1650nm (SMF);
Power Control and Angled Interface
The Agilent (now Keysight) 81577A is a Variable Optical Attenuator and offers 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.
It features power control functionality that allows you to set the output power level of the attenuator directly reducing test time.
