In power tunnels, underground passages, remote monitoring stations, and large warehouses, the most difficult "natural enemy" for communication lines to defend against is not a natural disaster, but the omnipresent rodent—the rat. According to industry statistics, approximately 30% to 50% of fiber optic cable failures in industrial environments are caused by rodent bites. Once a cable is severed, enterprises face not only expensive fusion splicing repair costs but also massive losses due to production downtime.

This is a critical issue in industrial and underground infrastructure. Standard plastic-jacketed fiber optic cables, even those with aramid yarn or glass yarn reinforcement, are often easily breached by the incisors of rodents.
The OFSCN® 85°C Seamless Steel Tube Fiber Cable addresses this vulnerability by utilizing a continuous, seamless stainless steel tube as the primary protective layer. From a mechanical perspective, this provides a “bulletproof” defense that is physically impossible for rodents to penetrate.
Technical Advantages for Rodent-Prone Environments:
- Physical Barrier: The 304 (or optional 316L) stainless steel tube typically features a diameter of 2.0mm or 3.0mm. This metal shell provides high crush resistance and a hardness level that rodents cannot overcome.
- All-Metal Protection: Unlike traditional “anti-rodent” cables that use chemical additives (which can lose effectiveness over time) or steel tape armor (which can have gaps), the seamless tube is a solid, gap-less cylindrical structure.
- Durability: Beyond rodent protection, it offers superior tensile strength and resistance to harsh environmental factors common in power tunnels and underground passages.
Product Visuals:
This cable is highly effective when used as a communication line or as a distributed fiber optic sensor (for temperature or strain) in environments where physical integrity is paramount.
