What accessories should I order with a 8163X power sensor module?

The optical power sensors Keysight Technologies offers are used for optical power measurements. The power sensors will not be able to operate as standalone instruments. The following accessories are needed:

A mainframe
An optical interface

The 8163x power sensor works with the 8163, 8164 and 8166 mainframes
