Bundle Tube Type all Dielectric ASU Self-Supporting Optical Cable

ASU

Bundle Tube Type all Dielectric ASU Self-Supporting Optical Cable

The structure of the optical cable is designed to connect 250 μm optical fibers. The fibers are inserted into a loose tube made of high modulus material, which is then filled with waterproof compound. The loose tube and FRP are twisted together using SZ. Water blocking yarn is added to the cable core to prevent water seepage, and then a polyethylene (PE) sheath is extruded to form the cable. A stripping rope can be used to tear open the optical cable sheath.

Packing And Mark

OYI cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease. Cables should be protected from moisture, kept away from high temperatures and fire sparks, protected from over-bending and crushing, and protected from mechanical stress and damage. It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.

Loose Tube Non-metallic Heavy Type Rodent Protected

The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.

Test report and certification provided.
