Blown Cable – 72F – G657A1 – Singlemode – 250µm – 12FO Tube – Per Metre

Blown Cable – 72F – G657A1 – Singlemode – 250µm – 12FO Tube – Per Metre

The Blown Cable – 72F – G657A1 – Singlemode – 250µm – 12FO Tube – Per Metre is a high-capacity fibre optic micro cable engineered for blown fibre installations in FTTH, FTTX and high-density telecommunications networks. Manufactured with 72 bend-resistant G.657A1 single-mode fibres, this compact cable delivers exceptional optical performance while maximising fibre density within microduct infrastructure.

Designed with 250µm bend-loss optimised fibres, the cable provides excellent flexibility and reliable signal transmission through microduct systems while maintaining outstanding mechanical performance. Its lightweight construction, water-blocked design and durable HDPE anti-rodent outer sheath provide long-term environmental protection and enable rapid, efficient installation.

Manufactured to meet stringent international standards including IEC, ITU-T, Telcordia GR-20, RoHS and REACH, this blown fibre cable is an ideal solution for telecom operators, broadband providers and infrastructure contractors requiring high-capacity, reliable fibre deployment.
