The production of GYTS (Layer Stranded Loose Tube) fiber cable involves several steps. GYTS cables are commonly used in outdoor installations and are known for their robust design and versatility. Here's a simplified overview of the manufacturing process:
1. Fiber Optic Stranding:
- Individual optical fibers are coated with a protective buffer to prevent damage during handling.
- The coated fibers are then stranded together to form loose tubes. These tubes provide flexibility and protection for the enclosed fibers.
2. Central Strength Member:
- A central strength member, often made of steel, is added to provide additional support and tensile strength to the cable.
3. Filling Compound:
- The interstices between the loose tubes and the central strength member are filled with a water-blocking filling compound. This compound helps to prevent the ingress of water, ensuring the long-term reliability of the cable.
4. Armor Layer (if applicable):
- For added protection in harsh environments, an armored layer may be added. This armor can be made of materials like steel or aluminum, providing increased resistance to external forces.
5. Inner Sheath:
- An inner sheath is applied to protect the core components of the cable. This sheath is typically made of polyethylene or another suitable material.
6. Stranding of Core Components:
- The central strength member, loose tubes, and any additional elements are stranded together to form the cable's core.
7. Water-Swelling Tape (if applicable):
- In some cases, a water-swelling tape may be included to enhance water-blocking properties, especially at cable entry points.
8. Outer Sheath:
- The final layer of protection, the outer sheath, is applied to shield the cable from environmental factors. This sheath is usually made of high-density polyethylene (HDPE) or other suitable materials.
9. Quality Control and Testing:
- The finished GYTS fiber cable undergoes rigorous quality control checks and testing. This includes measurements of optical performance, mechanical strength, and environmental resistance.
10. Packaging and Distribution:
- Once the cable passes quality control, it is packaged and prepared for distribution. Proper labeling and documentation are included for easy identification and installation.
Throughout the manufacturing process, adherence to industry standards and quality control measures is crucial to ensure the reliability and performance of the GYTS fiber cable. Please note that specific details and variations may exist depending on the manufacturer and the intended application of the cable.
