What welding methods are typically used for fiber optic cable trays
There are several methods to achieve this. The most popular ones include: mechanical welding - with the use of mechanical joints and thermal welding with the use of a welding machine, and the third option, i. the technique of polishing joints and gluing. During installation, all curvatures should be smooth. Although the process of installing fiber optic cables after laying them is not particularly difficult, the most problematic thing for installers (especially beginners) is the welding process, i. The whole process requires the welder to have only tools such as: a guillotine for cutting, cable shears, a stripper to remove the coating from the fibres and dustless wipes. Thanks to this, you can connect two ends of the cable with a.
