GYTA33 Steel Armored Outdoor Fiber Optic Cable for Underwater Installation
GYTA33 Fiber Optic Cable
The GYTA33 cable features optical fibers housed in PBT loose tubes filled with thixotropic gel. A steel wire serves as the central strength member, optionally coated with a PE layer for high-fiber-count configurations. Loose tubes are SZ-stranded around the core, and gaps are filled with water-blocking compounds. The cable is armored with thin round steel wires and a polyethylene outer sheath for enhanced protection.
Features:
-
Premium optical fibers ensure stable signal transmission.
-
Precisely controlled excess fiber length provides outstanding mechanical and thermal stability.
-
Gel-filled loose tubes safeguard fibers against stress and environmental factors.
-
Comprehensive water-blocking throughout the core ensures excellent moisture resistance.
-
Central strength member made of corrosion-resistant phosphated steel delivers strong tensile performance.
-
Longitudinal aluminum tape armor and stranded steel wire enhance crush resistance, bulletproofing, and underwater burial durability.
-
High-quality materials and manufacturing extend the service life to over 30 years.
Application:
Designed for underwater use in seas, rivers, and lakes, this submarine fiber optic cable supports high-capacity, long-distance communication between continents, islands, coastal facilities, and offshore platforms. Its robust structure is ideal for harsh environments requiring direct-burial and high mechanical strength.
