Optical fiber's core (typically silica glass, SiO₂) and surrounding components (coating, buffer tube, jacket) react differently to temperature changes, leading to two primary issues: signal attenuation and mechanical damage. In this work, we analyze the thermal effects occurring in optical fibres, such as the coating heating due to high power propagation in bent fibres and the fibre fuse effect. We describe the actual state of the art of these phenomena and our contribution to the subject, which consists on both. ABSTRACT Optical ber composite low voltage cable (OPLC) is an optimized way of carrying out the function of supplying electrical power and communication signals in a single cable. The status of an optic–electric composite high-voltage submarine cable (referred to as submarine cable) can be monitored based on optical fiber-distributed sensing technology, and at the same time, no additional sensor is needed in the monitoring system. Optical fiber's ability to withstand extreme heat and cold directly impacts signal integrity, network reliability, and maintenance costs, especially in harsh environments like industrial facilities, outdoor installations, and data centers.
