To effectively splice OPGW cables, begin by ensuring site safety through the establishment of an equal potential zone, then prepare and straighten the cable, remove the armor to access the fibers, splice the fibers using a fusion splicer, and secure the splice with a heat shrink. To effectively splice OPGW cables, begin by ensuring site safety through the establishment of an equal potential zone, then prepare and straighten the cable, remove the armor to access the fibers, splice the fibers using a fusion splicer, and secure the splice with a heat shrink. Splicing OPGW (Optical Ground Wire) cables requires following several precise steps—establishing site safety, preparing the cable, accessing the fibers, performing the splice with a fusion splicer, sealing the splice with a heat shrink sleeve, and finally installing the splice in a closure. Careful. Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed. In case you are wondering why light traveling through fiber optic cable does not actually travel at true light speed, it is because the glass that makes up. OPGW cables combine the functions of grounding and communication, with a optical fibers in the middle of the conductive cable. OPGW cables are installed on transmission and distribution power lines, above the high-voltage power conductors since acts as the protection from lightning strikes. OPPC. This fiber optic training course is designed for those who specify, design, install, construct or maintain aerial Optical Power Ground wire systems in investor-owned, Electric Power Utilities, REAs, Co-operatives, and municipal power networks. Students will learn about the latest construction. In this guide, we cover the basics of fiber optic splicing, how to perform splicing using two different methods, and finally some best practices to perform good fiber splicing.
