Steel Tape Armored fiber optic cable

Steel tape armored optical cable is a heavy-duty protective optical cable designed specifically to withstand high voltage and biting. It is designed for harsh mechanical and outdoor direct burial environments and has extremely strong protective capabilities.

Cable structure:

* Central reinforcement

* Optical fiber/fiber bundle tube

* Cable core

* Inner sheath

* Armoring layer

* Outer sheath

Features

* Extremely strong compressive strength:

This is the most prominent advantage of steel tape armor. The steel tape layer effectively resists enormous external pressure, preventing the optical cable from being flattened or damaged. This is crucial in direct burial installations, as it can withstand the backfill pressure from soil and rocks, as well as the pressure from vehicles passing on the ground.

* Excellent resistance to rodent bites:

Rodents such as rats and badgers can cause significant damage to communication lines. Ordinary unarmored optical cables are easily bitten through, but the steel tape's hardness prevents their teeth from penetrating, effectively protecting the internal optical fibers.

* Excellent moisture and humidity resistance:

The steel tape layer itself is metal and has good water resistance. In addition to the sealing at the armored joints and the waterproof sealant inside the cable core, multiple waterproof barriers are formed, ensuring long-term stable operation of the optical cable in humid environments or environments with high groundwater levels.

* Enhanced Mechanical Protection:

Besides resistance to compression and biting, the steel tape layer also enhances the overall impact and shear resistance of the optical cable, providing additional protection during construction or unexpected external impacts.

* Long Lifespan and High Reliability:

 Combining the above advantages, steel-tape armored optical cables are typically designed for a lifespan exceeding 25 years, making them ideal for network backbones or permanent installations in harsh environments.

Application:

Direct Burial: Directly buried underground, a common choice for infrastructure construction such as highways, railways, and industrial parks.

Tunnel and Pipeline Laying: Complex environments with potential risks of rockfalls or mechanical damage.

Areas with High Rodent Infestation: Forests, farmland, urban underground pipelines, and other areas with high rodent activity.

Harsh Industrial Environments: Factories, mines, and other places with the risk of being crushed by heavy objects.
