    Chapter 5 Tips and Techniques 5.3.1 Grounding with Modulation Most modulators have a BNC output that is connected to earth ground. This is not a problem as long as the laser anode or cathode is not also connected to earth ground. However, in many systems, it is. When it is, the following must be considered: When the anode is tied to earth ground, this effectively connects earth ground to the laser power supply, which can be up to +10V dc.
