Outdoor covered optical cable plays a vital role in modern communication networks, and its durability and protection measures under extreme weather conditions are the key to ensuring the stability and security of communication networks. Faced with weather conditions such as extreme temperatures, strong winds, heavy rain, hail, and lightning, outdoor covered optical cable needs to have excellent performance to cope with various challenges.In terms of material selection, the outer sheath of outdoor covered optical cable is usually made of strong materials such as polyethylene (PE) or polyvinyl chloride (PVC), which can effectively prevent ultraviolet radiation, chemical corrosion, and physical damage. For optical cables exposed to extreme temperatures, materials such as low-temperature resistant PE or thermoplastic elastomer (TPE) can be selected to ensure that the optical cable does not become brittle at low temperatures and does not soften excessively at high temperatures.In terms of waterproofing, outdoor covered optical cable usually has excellent waterproofing functions. For example, gel-filled tape or waterproof tape is used for sealing to prevent moisture from entering the interior of the optical cable. Moisture may freeze in cold weather and damage the optical cable, so waterproofing measures are essential.In order to enhance the mechanical strength and durability of the optical cable, some outdoor covered optical cables are also equipped with additional protective layers, such as metal armor or reinforcements. These protective layers can withstand strong winds, ice and snow loads, and physical impacts, providing additional protection for the optical cable.Under extreme temperature conditions, the flexibility of the optical cable and the thermal stability of the material are equally important. Too high or too low temperatures may cause the optical cable material to become brittle or deform, thus affecting its performance. Therefore, the design and material selection of the optical cable need to take into account the influence of temperature factors to ensure that it can still work properly under extreme temperatures.In addition to the above measures, regular inspection and maintenance are also important links to ensure the durability of outdoor covered optical cables. After extreme weather events, such as optical cable interruptions caused by severe convective weather, it is necessary to quickly initiate emergency responses, organize support personnel, emergency vehicles, and generators, and comprehensively strengthen the repair and inspection of communication facilities such as base stations, optical cables, and machine rooms.In summary, the durability and protection measures of outdoor covered optical cables under extreme weather conditions involve multiple aspects, including material selection, waterproof design, mechanical strength enhancement, and regular inspection and maintenance. These measures together constitute an effective barrier for the outdoor covered optical cable to cope with extreme weather challenges and ensure the stability and security of the communication network.
