316L Cold Rolled Stainless Steel Strip For Optical Cable/OPGW

Performance advantages
• Super corrosion resistance: Suitable for strong corrosion environments such as coastal areas, chemical parks, and sewage treatment plants. It can withstand salt spray (no rust in salt spray test for more than 5,000 hours), industrial waste gas (such as sulfur and chlorine gas) and seawater immersion for a long time, solving the problem of easy rust and breakage of ordinary steel belt optical cables.
• Enhanced mechanical protection: The tensile strength (≥480MPa) and toughness of 316L stainless steel belt are better than plastic sheaths. It can withstand stretching, extrusion and impact during laying, and protect the optical fiber from external force damage. It is especially suitable for complex laying scenarios such as direct burial, underwater or overhead.
• Moisture-proof and shielding: The closed stainless steel belt layer can effectively block water vapor penetration, and cooperate with the outer PE/PVC sheath to form a double moisture-proof barrier; at the same time, the metal belt has a certain electromagnetic shielding effect, reducing the impact of external electromagnetic interference on optical signal transmission.

Application scenarios
• Marine engineering: such as the shallow section of submarine optical cable and the connecting optical cable of offshore wind power platform, which can withstand long-term erosion by seawater and tidal impact.
• Chemical and industrial environment: Communication optical cables in chemical plants, printing and dyeing plants, etc., to resist acid and alkali leakage and high humidity corrosion.
• Special outdoor environment: Overhead optical cables in coastal areas and direct buried optical cables in saline soil areas to cope with high salt fog and high soil corrosion.
• Military and security fields: Field communication lines with high protection level requirements, taking into account corrosion resistance and anti-destruction capabilities.

Differences from ordinary steel belt optical cables

Compared with commonly used galvanized steel belt or 304 stainless steel belt optical cables, 316L stainless steel belt optical cables have a 3-5 times higher resistance to chloride ion corrosion and a service life of more than 20 years (ordinary steel belt optical cables may fail in 5-10 years in coastal environments), but the cost is high and is usually used in special scenarios with strict reliability requirements.

Its core value lies in the excellent corrosion resistance of 316L stainless steel belts to ensure long-term stable communication of optical cables in extreme environments, which is a key solution for optical fiber transmission in highly corrosive environments.
