Parameters of optical fiber cable PE

PE-jacketed optical fiber cables are designed for durability, environmental resistance, and stable optical performance, typically using ITU-T G.652D fibers with loose tube construction and aramid reinforcement.

Optical Parameters

• Fiber Type: Single-mode fibers, commonly ITU-T G.652D, optimized for low attenuation and low water peak loss .
• Attenuation: Typically ≤0.35 dB/km at 1310 nm and ≤0.22 dB/km at 1550 nm, ensuring minimal signal loss over long distances .
• Wavelength Range: 1310 nm, 1550 nm, and sometimes 1625 nm for testing and CWDM applications .
• Proof Testing: Fibers are proof-tested to remove intrinsic flaws and ensure long-term reliability .

Mechanical and Structural Parameters

• Construction: Loose tube design with high-modulus plastic tubes filled with water-blocking compounds .
• Strength Members: Aramid yarns provide high tensile strength and protect fibers from mechanical stress .
• Outer Sheath: Polyethylene (PE) jacket offers excellent environmental protection, UV resistance, and mechanical durability .
• Color Coding: Fibers are color-coded for identification according to standard sequences, facilitating installation and maintenance .

Environmental and Operational Parameters

• Temperature Range: Typically -40°C to +70°C for operation, with short-term exposure up to +85°C .
• Water Resistance: Loose tubes filled with waterproof compounds and PE sheath ensure resistance to moisture ingress .
• Tensile Load: Designed to withstand installation and operational tensile loads without fiber damage, often tested under short-term and long-term conditions .
• Sag and Span: For aerial ADSS cables, maximum pole span and initial sag are specified to maintain mechanical integrity under load .

Compliance and Standards

• International Standards: Compliant with IEC 60794 series, ITU-T G.652D, and ISO 9001/14001 quality management systems .
• Service Life: Designed for a typical service life of 25 years under normal environmental conditions .
• Testing: Periodic qualification tests for optical, mechanical, and environmental performance ensure durability and reliability . PE-jacketed optical fiber cables are widely used in outdoor, aerial, and industrial applications due to their robust mechanical protection, environmental resistance, and stable optical performance, making them suitable for long-term deployment in harsh conditions .
