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. The procedure for preparing OPGW cables for fusion splicing consists of several steps. Different types of optical closures are used. First, a heat-shrink tube is placed over the OPGW cable. After that, the cable is secured with a clamp or another suitable tool to ensure stability while removing the. 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. Ensure Your Splicing Tools are Clean – #2. For network managers and technicians, a poor splice can lead to significant signal degradation, network downtime, and costly troubleshooting. At Turn-Key. General OPGW based Fibre Optic network being established by Power Utilities for catering data & voice communication requirements. Hence, it is specifically made with an armour of metal on the outside to protect the enclosure from electrical fields.
