We are going to be routing 12 metallic-sheathed fiber optic cables across our plant floor (usual mix of 480V, welding, etc) and into the datacomm room. It seems to me that the metallic sheath should be grounded at the point where the cables enter the room, to drain off any induced voltages on the sheath.
In the dim past I used IBM Type 1 cable, and the termination racks had a tower that the cable would run through. You would strip off 1 cm of the insulation at the point where the cable ran through the tower and crimp a tab on the tower onto the metallic shield, then ground the tower. I would think this should work for the fiber cables also. However, I can no longer locate any such part. Any suggestions?
