The GBDH848 is a high-performance outdoor optical fiber cable designed to withstand the rigors of harsh environmental conditions. Featuring a multi-loose tube construction, this cable offers superior protection and reliability for a variety of applications, including industrial backbone, campus backbone, building backbone (riser), and horizontal cabling, as well as networks for industrial, telecom, cable TV, and broadcast use.
Key Features
- Robust Construction: The GBDH848 boasts a durable design that includes aramid yarns as the strength member, a polyethylene inner jacket, a corrugated steel tape armor for full rodent protection, and a polyethylene outer jacket. This combination of materials ensures the cable can withstand the challenges of outdoor installations, such as direct burial, duct/tunnel/trench placement, and exposure to the elements.
- High Fiber Count: With 48 single-mode (OS2) fibers spread across 6 loose tubes, the GBDH848 offers ample capacity for high-bandwidth applications, making it a suitable choice for backbone and distribution networks.
- Fiber Grade Compliance: The fibers used in the GBDH848 cable comply with the ITU-T G.652.D and G.657.A1 standards, ensuring reliable performance and compatibility with a wide range of optical networking equipment.
- Optimal Optical Performance: The GBDH848 features low attenuation values, with a maximum attenuation of 0.39 dB/km at 1310 nm, 0.24 dB/km at 1550 nm, and 0.29 dB/km at 1625 nm, ensuring efficient signal transmission over long distances.
