GYTA Heavy Armored Direct Burial Optical Cable (4-144 Cores)
The GYTA heavy-armored direct burial optical cable is designed for harsh outdoor environments requiring high mechanical strength and moisture resistance. With a stranded loose tube structure and double steel tape armor, it supports fiber counts from 4 to 144 cores, making it ideal for long-distance backbone networks, access networks, and direct burial applications.
Flexible Core Counts: Available from 4, 6, 8, 12, 24, 48, 72, 96, to 144 cores to meet various project requirements.
Heavy Double Armor: Corrugated steel tape double-armored construction provides excellent crush resistance, tensile strength, and rodent protection, perfect for direct burial.
Single Mode Fiber: Compatible with G.652D standard, ensuring low attenuation and high bandwidth for long-distance transmission.
Stranded Loose Tube Design: Optical fibers are placed in loose tubes around a central strength member, improving temperature performance and tensile stability.
Waterproof & Anti-Moisture: Water-blocking compound or yarn inside the cable core prevents water penetration, ensuring long-term reliability.
Durable Outer Sheath: Black polyethylene (PE) sheath offers high resistance to abrasion, corrosion, and UV radiation, suitable for direct burial in various soil conditions.
