The Keysight Agilent HP 81623A optical heads are specially designed for low PDL , low spectral ripple and high return loss and are used for optical component tests. The optical heads have to be operated with the single (Keysight Agilent HP 81618A) or dual (Keysight Agilent HP 81619A) interface modules. The heads come with a magnetic D-shape adapter and provide a safe stand. The Keysight Agilent HP 81623A is the predecessor to the Keysight Agilent HP 81623B. Here is Keysight Agilent HP's description of the difference between these two models: Most of the functionality of the Keysight Agilent HP 8152x optical heads was carried over when Keysight Agilent HP first introduced the Keysight Agilent HP 8162xA family of optical heads. However, the Keysight Agilent HP 8162xA optical heads did not have an analog output available. The Keysight Agilent HP 8162xB models, with the exception of the Keysight Agilent HP 81625B (now replaced by the Keysight Agilent HP 81626B), all offer an analog output on the optical head.
