How to ground the optical cable shielding layer
With single-ended grounding, it is usually better to ground the cable shield at the source end, because that is the reference for the signal voltage. However, if the signal source is floating, grounding the shield at the load end is preferable. Low-frequency cable shield grounding At low frequencies the primary purpose of a shielded cable is to prevent electric-field coupling from 50/60 Hz power lines. No practical shield provides magnetic-field protection at low frequency. For low frequencies, shielded twisted pair is often used: the. When it comes to running shielded twisted-pair (STP) cabling, grounding might not be the first thing you think about. But how you ground your cables can make the difference between a reliable, noise-free network and one plagued with mysterious issues.
