GYTS Single Mode Multimode Duct Outdoor Fiber Optic Cable

What is GYTS Fiber Optic Cable?

The GYTS fiber optic cable is a type of outdoor armored cable commonly used in telecommunication and data transmission.

       The fibers, single mode or muti mode , are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. 

       The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.

Key Features:

* Loose Tube Construction: The optical fibers are loosely housed in protective tubes that can absorb stress and adapt to environmental changes like temperature variations.

* Steel Tape Armor: Provides mechanical protection, making the cable resistant to external forces such as pressure from underground installations or rodent damage.

* Water-Blocking Materials: GYTS cables typically include water-blocking gels or tapes to prevent moisture penetration, protecting the fibers from water damage.

Applications:

* Outdoor Installation: Ideal for outdoor environments, particularly for direct burial or in ducts.

* Telecommunications: Suitable for long-distance data transmission,and overhead laying

* LAN/WAN Networks: Commonly used in large-scale networks that require durable and robust cabling.

Advantages:

* High Tensile Strength: The combination of steel tape and loose tube construction provides excellent durability.

* Moisture Resistance: Water-blocking materials protect the cable in wet environments.

* Cost-Effective: Compared to other armored cables, GYTS is both affordable and reliable for outdoor use.

Characteristics

* Good mechanical and temperature performance

* High strength loose tube that is hydrolysis resistant

* Special tube filling compound ensure a critical protection of fiber

* Crush resistance and flexibility

* PE sheath protects cable from ultraviolet radiation

* The following measures are taken to ensure the cable watertight:

* Steel wire used as the central strength member

* Loose tube filling compound and 100% cable core filling

* PSP enhancing moisture-proof
