Air-blown optical cable model and specification table

Air-blown optical cables are lightweight, high-capacity fiber cables designed for installation via compressed air, offering flexible deployment, low friction, and robust mechanical and optical performance.General FeaturesAir-blown optical cables are engineered for long-distance fiber deployment using compressed air, with small diameters, light weight, and low sheath friction to maximize blowing distance and installation efficiency . Key features include:Mechanical Strength: Aramid yarn or central strength members provide tensile load support and resistance to bending .Environmental Protection: Water-blocking components, UV-stabilized jackets, and flame-resistant options for riser and plenum applications .Flexible Fiber Deployment: Fibers can be added or replaced without disturbing the duct system, supporting modular network expansion .Fiber Types and Optical ParametersAir-blown cables support both single-mode (SMF) and multimode (MMF) fibers, with specifications for attenuation, bandwidth, and Ethernet compatibility:Fiber TypeMax Attenuation (dB/km)Min Bandwidth (MHz·km)10G Ethernet Max Distance (m)40/100G Ethernet SupportOM1 62.5/1253.5 @ 850 nm200300YesOM2 50/1253.5 @ 850 nm500600YesOM3 50/1253.0 @ 850 nm15001000YesOM4 50/1253.0 @ 850 nm35001040YesSM OS2 (G.652D/G.657.A1)0.4 @ 1310/1550 nmN/AN/AYes Bend-insensitive fibers (BIF) are commonly used to reduce signal loss in tight bends.Mechanical and Physical ParametersAir-blown cables are available in various fiber counts and diameters, with typical mechanical specifications:ModelFiber CountNominal Diameter (mm)Weight (kg/km)Max Tensile Load (Short/Long Term, N)Min Bend Radius (Short/Long Term, mm)ENT-A SM-663.69.5445 / 13330 / 20ENT-A SM-24243.6–3.811–14445 / 13330 / 20ENT-A SM-72724.520.81600 / 45090 / 45ENT-A SM-96964.523.81600 / 45090 / 45 Cables are designed for micro-duct compatibility, often fitting 6 mm ID ducts, enabling high-density fiber pathways.Construction and DesignAir-blown cables typically feature:Loose Tube or Central Tube Design: Fibers are color-coded and gel-filled for protection .All-Dielectric Construction: No metallic components, suitable for environments requiring non-conductive cables.Outer Jacket: PE or LSZH materials, UV-stabilized, and water-blocked for durability.Ripcords: Facilitate easy jacket removal during installation.ApplicationsData center interconnectsHorizontal and backbone distributionLow-cost fiber upgrades and migrationInternal and external micro-duct systems Installation AdvantagesBlowing Distance: Long-distance fiber deployment without splicing.Modular Expansion: Fibers can be added later without replacing the duct.Reduced Labor and Cost: Faster installation and lower material handling requirements. Air-blown optical cables provide a highly flexible, reliable, and scalable solution for modern fiber networks, combining mechanical robustness, optical performance, and ease of installation.
