Description
The A-DQ(BN)2Y(SR)2Y single loose tube cable is designed for outdoor routes where compact construction must be combined with enhanced mechanical and rodent protection. At its core, a gel-filled loose tube houses up to twelve optical fibers, providing controlled fiber management and stable optical performance under thermal variations, micro-bending effects and moisture exposure. The single-tube configuration simplifies identification and splicing, making it a practical choice for access and distribution networks.
Around the central tube, non-metallic strength members support the cable during installation, while a cylindrical steel armour layer (SR) provides robust protection against mechanical impact, crushing forces and rodent attack. The metallic armour also improves resistance to localized damage in direct-buried or exposed environments.
The A-DQ(BN)2Y(SR)2Y structure features a double PE jacket: an inner polyethylene sheath that stabilizes and protects the core and armour interface, and an outer polyethylene sheath that delivers additional environmental shielding. This dual-sheath concept enhances long-term resistance against abrasion, moisture ingress, chemicals and UV exposure, supporting reliable performance in diverse soil conditions, ducts and shallow burial applications.
Engineered for balanced stiffness and handling, the cable supports efficient pulling over long distances while maintaining fiber integrity and controlled attenuation. Its combination of steel armour, double jacket and gel-filled loose tube ensures dependable service in challenging outdoor deployments such as rural distribution routes, industrial facilities, utility corridors and telecom access segments where both mechanical robustness and long-term stability are critical.
Manufactured in accordance with relevant IEC, EN and ITU-T recommendations, the A-DQ(BN)2Y(SR)2Y single loose tube cable delivers durable, high-performance connectivity for modern broadband and telecommunication infrastructures.
