The grounding method of the optical cable of the splice box on the structure: the top of the structure, the lowest fixed point (before the remaining cable) and the end of the optical cable should be connected to the structure with a reliable electrical connection through. The grounding method of the optical cable of the splice box on the structure: the top of the structure, the lowest fixed point (before the remaining cable) and the end of the optical cable should be connected to the structure with a reliable electrical connection through. This paper, OPGW Grounding Techniques for Safe Fiber Splicing, outlines critical safety protocols and procedures for preparing Optical Ground Wire (OPGW) splicing on high-voltage transmission lines. OPGW serves a dual function as both a ground wire for fault current protection and a medium for. W) into a splice box is to connect one OPGW to tion of Optical Ground Wire into the AFL SB01 splice box. The first step is to determine the amount of cable needed to take advantage of this feature. This amount of cable includes the distance from the splice enclosure mounting position on the tower to the ground plus any additional length desired to transport the splice drawer. Overhead ground wire composite optical cable (OPGW) should be reliably grounded at the entry portal to prevent the optical cable from being broken by induced voltage and interrupted when a short circuit occurs in the line. The grounding requirements are as follows: 1. Be sure to follow ALL guidelines and recommendations set forth by the operator. When your at a wooden structure on a. Is there any NEC / NESC or other requirement to ground/bond the tracer wire on communication wire on one end (Fiber in this case)? There is a 138kV transmission line near a large solar farm and a 7.
