There are many types of defects, and common cable surface defects include pores, pinholes, bubbles, etc. They will have a certain impact on the insulation performance, mechanical. The construction process and problem analysis of the optical cable are as follows. The optical cable is a communication line in which a certain number of optical fibers form the core according to a certain method, and the outer sheath is covered, and some are also covered with the outer sheath to. Setting up an optical cable sheath extrusion line is a critical step in manufacturing robust optical cables designed to withstand environmental stress and ensure reliable signal transmission. However, like any technology, fiber optic systems can encounter issues that affect performance. Let's dive into the most frequent headaches, how to spot them, and, most importantly, how to get your network back on track. Fiber optic cables are the unsung heroes behind lightning-fast data.
