Armored fiber optic cables incorporate a metal or non-metal armor layer in their structure, significantly enhancing their mechanical protection performance and making them suitable for a variety of demanding environments. Their main advantages include the following:
High Mechanical Strength and Protection:** The armor layer (such as steel tape, aluminum tape, or aramid) effectively resists external pressure, tension, impact, and rodent damage, making them particularly suitable for direct burial, conduit, or aerial applications where mechanical damage is likely.
For example, some models have a tensile strength exceeding 3000N and a lateral pressure resistance exceeding 2000N/100mm.
Environmental Adaptability and Durability: Armored fiber optic cables are resistant to temperature variations (-60℃ to +65℃), humidity, UV radiation, and chemical corrosion, allowing them to operate reliably for extended periods in harsh conditions such as outdoor, industrial, or military environments, reducing failures caused by environmental factors.
