What happens when optical fiber cables get very hot
Higher temperatures tend to increase the attenuation due to alterations in the glass's refractive index. 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. Harsh heat can degrade normal fiber optic cables, causing downtime, data loss, or expensive replacements. Thus, the conjugation of high power propagation and tight bending, resulting from the actual FTTH infrastructures, is responsible for fibre lifetime reduction, mainly caused by the local increase of the coating temperature. High temperature impacts several internal parts in different ways: Laser diodes (DFB, VCSEL): Output power and wavelength shift with temperature.
