I have doubts how to earth terminate a telecom cable armour, shield (Tape) & drain wire. The termination must be suitable for EMC protection. Can I terminate the armour +shield+tape into the same Armour clamping gland?
at the tip of your cable, put a terminal log depends the size of your cable and terminate it to grounding sysyem.all ground cable must be terminated into the grounding system ex.( buildings, telecom exchange,or cell site) dont terminate with the same kind of cable it must be a grounding rod.
In my opinion, you have to connect the armour to the metal cabinets, at
the two ends of the cable, using EMI cable glands. Then you can earth the
internal shield + tape at only one point. (Preferably at the remote end from
the source of interference).
