Dimensions of Indonesian Fiber Optic Logging Cables

Indonesian fiber optic logging cables typically range from compact 3x2 mm microcables to larger armored outdoor and submarine cables, with dimensions varying by fiber count, protective layers, and installation type.

Indoor and Access Network Cables

For indoor or FTTX (fiber-to-the-home) applications, Indonesian manufacturers produce small-diameter fiber optic cables capable of accommodating 1 to 8 fibers, with approximate dimensions of 3x2 millimeters. These cables are reinforced with two non-metallic FRP (Fiber Reinforced Plastic) elements to protect the optical fibers, and are coated with LSZH (Low Smoke Zero Halogen) material to prevent flame spread and toxic gas release. They are available in PVC or polyethylene (PE) coatings, with indoor variants typically in white or yellow, and outdoor variants in black .

Outdoor and Buried Cables

Outdoor cables designed for pole, wall, or underground installation are larger due to additional protective layers. These cables often include:

• UV-resistant and waterproof coatings to withstand sunlight, rain, and temperature fluctuations.
• Anti-rodent protection for durability in outdoor environments.
• Armored structures for mechanical protection, especially in direct-buried or plowed installations.
• HDPE (High-Density Polyethylene) microducts for underground deployment, which are flexible, lightweight, and corrosion-resistant . The exact diameter depends on fiber count and the number of protective layers, but typical outdoor cables are larger than indoor microcables, often ranging from 6 mm to 20 mm depending on design and fiber capacity.

Submarine Cables

Submarine fiber optic cables used for inter-island or international data transmission are heavily armored to withstand high pressure, low temperatures, and corrosive environments. Each optical fiber is protected by multiple layers, including:

• Armored steel or copper layers for mechanical strength.
• Water-blocking materials to prevent moisture ingress.
• Special coatings for long-term durability in deep-sea conditions . These cables are significantly larger than terrestrial cables, with diameters often exceeding 20 mm, depending on fiber count and protective requirements.

Summary

• Indoor microcables: ~3x2 mm, 1–8 fibers, LSZH coating, FRP reinforcement .
• Outdoor cables: 6–20 mm, armored or UV-resistant coatings, suitable for poles, walls, or buried installation .
• Submarine cables: >20 mm, heavily armored, water-blocking layers, designed for deep-sea durability . The dimensions of Indonesian fiber optic logging cables vary widely depending on application, fiber count, and protective requirements, with manufacturers like PT ZTT Cable Indonesia and PT CCSI providing tailored solutions for indoor, outdoor, and submarine deployments .
