Cavo in fibra ottica subacqueo a fascio centrale
- There are 2-24 optical fibers in an oil-filled loose casing, filled with water-resistant tape.
- The waterstopper is wrapped in a spiral around the center bundle, and spun sand or glass filaments around the bundle to provide protection and increase tensile strength.
- The PE sheath of the fiber optic cable can achieve the waterproof function.
- In the case of direct burial, steel wire armor and wrinkled steel tape armor plus an optional PE inner jacket In the case of direct burial, steel wire armor and wrinkled steel tape armor plus an optional PE inner jacket.

Applicazioni:
Outdoor center-beamed underwater fiber optic cables have good tensile strength, lateral pressure resistance and excellent mechanical properties, and can be well adapted to the surrounding working environment. Small diameter, light weight, with good tensile strength and lateral pressure resistance, suitable for underwater working environment, used to connect communication equipment and persistent information system.
