Description
Overview
The Keysight 81624A is an InGaAs optical head engineered for low PDL, low spectral ripple, and high return loss performance. It interfaces with single (81618A) or dual (81619A) interface modules and integrates with lightwave mainframe models 8163A/B, 8164A/B, and 8166A/B. Unlike the later 81624B, the 81624A does not include analog output capability.
