Anti-freezing measures for underground optical cables
The preferred approach to prevent ice-freezing effects is to ensure that all cables are installed inside of a small diameter PE subduct, which in turn is contained in the larger conduit. Corning recommends a maximum fill ratio for subducts of 65%. Yet, outdoors, they face temperature swings, moisture, UV exposure, rodents, and human interference. In addition to bridge crossings, fiber is susceptible to ice damage at any location where duct is exposed to freezing temperatures, such as culverts. When using fiber optic cables in an area that can see freezing temperatures, precautions must be taken to provide long term cable and fiber reliability. This can lead to mechanical stress and potential. This article introduces an investigation into the mechanism of damage to optical fiber cables and polyethylene pipes in lifting pipes installed in cold regions. We carried out examinations using a physical simulation model in a large thermostatic room. This upward force can disrupt the stability of underground structures, including.
