Standardized optical cable products

Standard optical cables include single-mode and multimode fibers designed for indoor, outdoor, and specialized applications, conforming to international standards for performance, reliability, and safety.

Types of Optical Cables

Single-mode fibers (SMF) are optimized for long-distance transmission with low attenuation, typically conforming to ITU-T G.652, G.655, and G.657 standards . Multimode fibers (MMF), such as OM3 and OM4, are used for shorter distances and high-speed data centers, offering high bandwidth and low modal dispersion . Cables are available in various constructions:

• Outdoor cables: UV-resistant, water-blocked, armored or non-armored, suitable for harsh environments .
• Indoor cables: Flexible, flame-retardant, and suitable for building installations .
• Universal (indoor-outdoor) cables: Designed for both environments, often with rodent protection or aluminum-laminated polyethylene sheaths .
• Mini and micro cables: Compact designs for micro-duct systems, ideal for Next Generation Access networks like FTTC, FTTB, and FTTH .

Key Features and Standards

Optical cables are manufactured to meet international standards ensuring quality, performance, and interoperability:

• IEC 60793 & 60794: Define optical and mechanical characteristics of fibers and cables .
• Telcordia GR-20: Covers outdoor cable reliability and environmental testing .
• TIA-568.3-D & ISO/IEC 11801: Specify structured cabling and connectivity requirements .
• Connector standards (IEC 61300 series): Ensure low insertion loss and stable performance in data centers . Cables are tested for attenuation, bending loss, tensile strength, temperature stability, and environmental resistance, ensuring reliable operation in industrial, telecom, and data center applications .

Specialized Constructions

Some optical cables include:

• Armored cables: Steel or aluminum for mechanical protection .
• ADSS (Aerial Dielectric Self-Supporting): Metal-free cables for overhead deployment .
• Bend-insensitive fibers: Reduce signal loss in tight bends, compatible with G.652 fibers .
