Duct Cable – 288F – G657A1 – Singlemode – Per Metre

Duct Cable – 288F – G657A1 – Singlemode – Per Metre

The Duct Cable – 288F – G657A1 – Singlemode – Per Metre is a high-capacity loose tube fibre optic cable engineered for duct installations across telecommunications, broadband and FTTX networks. Designed with 288 bend-resistant G.657A1 single-mode fibres, it delivers exceptional optical performance with ultra-low attenuation, making it ideal for backbone networks, large-scale fibre distribution and high-density infrastructure projects.

Its water-blocked loose tube construction incorporates gel-filled tubes, water-swellable yarn and a central FRP strength member to protect against moisture ingress and mechanical stress. The durable HDPE anti-rodent outer sheath provides outstanding environmental protection and long-term reliability, ensuring dependable performance in underground duct installations.

Optimised for conventional blowing and pulling installation methods, the cable combines high tensile strength, excellent crush resistance and colour-coded fibres for simplified identification during splicing and termination. It is an ideal solution for telecom operators, broadband providers and data infrastructure projects requiring maximum fibre capacity and dependable long-term performance.
