HP-Agilent/Keysight 81625B

The optical heads have to be operated with the single (Agilent 81618A) or dual (Agilent 81619A) interface modules. They are used in lightwave mainframe models 8163A/B, 8164A/B and 8166A/B. The Agilent 81625B optical heads are specially designed for low PDL , low spectral ripple and high return loss and are used for optical component tests. The heads come with a magnetic D-shape adapter and provide a safe stand. – Large Area InGaAs Sensor – Optical Range of 850 to 1650 nm – Power Range of +27 dBm to -70 dBm
