Engineered for harsh‑environment outdoor deployment, this stranded loose‑tube fiber optic cable delivers superior mechanical safeguards for field‑level networking. Four optical fibers are housed within a gel‑filled PBT loose tube to buffer glass elements against environmental stress. A central metallic strength member (PE‑jacketed steel wire as an option) forms the core backbone; loose tubes and filler components are helically stranded around it to build a dense, round cable core. Water‑blocking filling compound together with steel‑tape wrapping encloses the core to block moisture ingress, and a durable black polyethylene outer jacket finishes the cable structure.
It achieves 1500 N short‑term tensile load capacity alongside 1000 N/100 mm compression performance. Functional temperature covers ‑40 °C up to +60 °C. Well‑suited for conduit routing, overhead stringing and shallow direct‑burial scenarios that call for baseline armor performance and dependable moisture‑sealing capability.
Product Advantage
1.Dual‑Layer Reinforced Armor System for Superior Mechanical Durability
Built with corrugated PSP steel tape paired with dual parallel steel‑wire reinforcement, this cable reaches 3000 N short‑term tensile capacity and 3000 N/100 mm anti‑crush rating. The hybrid reinforcement outperforms conventional single‑armor cables, defending against rock friction during underground laying, rodent gnawing inside conduits, and mechanical impact from construction machinery or heavy surface loads. It is a reliable pick for rocky ground burial, rodent‑prone ducts and heavy‑use industrial premises where ordinary fiber cables are prone to premature failure.
2.Multi‑Level Moisture‑Blocked Loose‑Tube Architecture
Hydrophilic filling gel fills the interior of each PBT loose tube, whilst supplementary water‑swellable materials are deployed between tube assemblies and PSP shielding layers. The full water‑blocking construction complies with IEC 794‑1‑F5B standards. It maintains stable transmission even in water‑logged ducts or occasional short‑term immersion, eliminating signal drift triggered by water intrusion. Inner gel compound also delivers cushioning for optical fibers, mitigating micro‑bending loss and securing consistent low‑attenuation performance through long‑term service cycles.
3.Enhanced Pull‑Resistant Performance for Long‑Reach Field Deployment
Rated for 3000 N short‑term tension resistance, the reinforcement combination of steel wires and PSP tape evenly disperses pulling stress across the whole cable body and avoids concentrated strain on bare fibers. This greatly lowers fiber breakage risk during installation. It fits overhead pole‑to‑pole runs, river‑span aerial crossings and long‑haul duct pulling jobs that face frequent tension surges during cable laying.
4.Broad Temperature Adaptability & Practical Bending Properties
Stable working performance is guaranteed within ‑40 °C ~ +60 °C ambient range; permissible installation ambient can drop to ‑10 °C. Minimum bend radius stands at 10× cable outer diameter under static unloaded state and 20× outer diameter under tension‑loaded conditions. Such bending tolerance supports routing inside confined manhole cavities and cable tray layouts. UV‑stable PE outer sheath provides resistance against ozone erosion and common chemical agents, extending service life for all‑weather outdoor exposure.
5.Space‑Sized Light‑Weight Design for Reinforced‑Grade Cable
Even equipped with heavy‑duty double reinforcement, the cable keeps outer diameter at 12.4 mm with unit weight of 150 kg/km. Compared with competing heavy‑armor fiber variants, it features slimmer profile and lower mass. Compact dimensions simplify on‑site handling, reel storage, transportation and field laying work, without sacrificing the high‑level mechanical robustness demanded by rigorous outdoor networking projects.
