Telenco Duct Cable G657A1 SM 12F (OQM 4km) – per metre
The Telenco Single-Mode (SM) Duct Cable 12F is a high-performance loose-tube optical fibre cable designed for duct installations in modern telecom and broadband networks. It integrates bend-insensitive G.657A1 fibres, water-blocked loose tubes, and a durable HDPE outer sheath to deliver exceptional signal integrity, mechanical strength, and long-term stability, even in harsh outdoor environments.
Engineered for FTTH and FTTX deployments, this compact 12-fibre cable combines robust protection with flexibility, making it ideal for both short- and long-haul duct installations. The water-blocking elements and central FRP strength member ensure consistent reliability and ease of installation for professional network operators.
Key Features:
-
High-Performance Fibre Optic Cable – Supports 12 fibres for small-scale or distribution-level telecom and data applications.
-
Low Attenuation G.657A1 Fibre – Ensures minimal signal loss and superior optical performance.
-
Water-Blocked Protection – Gel-filled loose tubes and water-swellable yarn provide moisture resistance and long-term durability.
-
Rugged HDPE Outer Sheath – Anti-rodent and abrasion-resistant, designed for duct and underground installations.
-
Central Strength Member (FRP Rod) – Reinforces tensile strength for safe cable pulling and long-distance runs.
-
Easy Fibre Identification – Colour-coded fibres simplify splicing, termination, and maintenance.
-
Optimised for Duct Installation – Suitable for standard pulling, jetting, or blowing techniques.
