OM4 Multimode Central Tube Fiber Optic Cable GYXTW 24 Core Outdoor Crush

The OM4 Multimode Central Tube Fiber Optic Cable GYXTW 24 Core Outdoor Crush Resistant is a high-performance central tube outdoor fiber optic cable engineered for reliable optical transmission in demanding outside-plant environments. Manufactured in China under strict process control, this cable positions 24 optical fibers inside a loose tube made of high-modulus PBT, filled with water-resistant compound to keep the core dry. Two parallel phosphatized steel wires and a steel-plastic composite armor deliver outstanding tensile and crush resistance, while the PE outer sheath protects the assembly against moisture, UV exposure and mechanical stress.

Designed for outdoor fiber connection along building backbone applications, network links and inter-building bridges, this cable meets the industry-regulated requirements of optical transmission, mechanical protection and flammability. Its central tube structure provides excellent mechanical and temperature performance, and the PE jacket offers dependable protection across a wide operating range. With 2-24 core configurations and both single-mode and multimode fiber options, it adapts flexibly to FTTH, campus backbone, metropolitan and access network deployments.

• Central Tube Structure: Loose-tube design with high-modulus PBT delivers excellent mechanical strength and stable temperature performance.
• Waterproof Construction: Water-resistant compound filling plus water-blocking material and PSP armor keep the cable fully watertight.
• High Tensile Strength: Two parallel phosphatized steel wires provide 1500N short-term and 600N long-term tensile capacity.
• Superior Crush Resistance: Steel-plastic composite belt armor withstands 1000N/100mm short-term crushing force for reliable burial and aerial use.
• OM4 Multimode (50/125) Transmission: Optimized fiber geometry with 3.0/1.0 dB/km typical (850/1300nm) attenuation ensures clean, low-loss optical links.
• Wide Temperature Range: Operates reliably from -40°C to +60°C, suitable for harsh outdoor climates year-round.

This central tube fiber optic cable is purpose-built for outdoor fiber connection, building backbone networks, campus and metropolitan links, and inter-building bridges. It is the cable of choice for direct burial, duct and aerial installations where mechanical protection and moisture resistance are essential.

The OM4 24-core configuration delivers high effective modal bandwidth for 40G/100G parallel optics and 10G links up to 550m, providing future-proof capacity for dense campus and data center interconnect backbone deployments.

Each cable is wound onto a sturdy wooden drum or plywood reel with protective lagging, then secured for export shipping. Standard drum lengths are available in 1km, 2km and 4km configurations, with custom lengths supplied on request. Cable ends are sealed to prevent moisture ingress during storage and transit.

Quality is assured through full traceability: every fiber is tested for attenuation and geometry, every cable undergoes mechanical testing for tensile and crush resistance, and water permeability is verified in accordance with YD/T 769-2018. Our factory operates a documented quality management system and supplies test reports with each batch, so installers can commission networks with confidence.
