Hi every one

I am using 40G clock. My friend told me that the clock is connected with ground, which is a one end grounded signal.

I dont understand why is this?

Since the modulator is also connected with ground at one end.

A ground loop will be formed to absorb noises, is that correct?

Why does this happen?

Thank you very much.
