Optical Head 750 nm - 1800 nm, Ge

+10 dBm to -80 dBm

HP (now Keysight) 81623A Optical Head Ge, +10dBm to -80dBm output range,

750 nm to 1800 nm wavelength range, for use with Agilent Lightwave Mainframes.

The Agilent (now Keysight) 81623A optical head is specially designed for low PDL, low spectral ripple and high return loss and is used for optical component tests.

The optical head has to be operated with the single 81618A or dual 81619A interface modul.

The head come with a magnetic D-shape adapter and provide a safe stand.

The 81623A is the predecessor to the 81623B. The difference between these two models:

Most of the functionality of the 8152x optical heads was carried over when Agilent (now Keysight) Technologies first introduced the 8162xA family of optical heads.

However, the 8162xA optical heads did not have an analog output available.

The 8162xB models, with the exception of the 81625B (now replaced by the 81626B), all offer an analog output on the optical head.
