CCOFC GYFC8Y Optical Cable Specification

1. Product Overview

CCOFC GYFC8Y is a figure-8 self-supporting aerial optical cable with loose tube stranded structure, non-metallic strength member, semi-dry water-blocking design and PE outer sheath. It integrates optical communication unit and galvanized steel messenger wire into one figure-8 shape, enabling direct aerial installation without extra supporting lines. It complies with YD/T 1155-2011 and IEC 60794-1-2, widely used for outdoor access network, rural communication, community and overhead line deployment. Fiber count ranges from 2 to 144 cores.

2. Key Features

· Integrated Figure-8 Self-Supporting: No additional messenger wire; simple aerial installation, saves construction cost.

· Non-metallic Cable Core: Insulating and anti-electromagnetic interference, suitable for overhead near power lines.

· Semi-dry Design: Easy stripping, splicing and maintenance with stable water-blocking performance.

· Lightweight & Compact: Small outer dimension, low load on poles; overall dimension approx 9.3×16.0 mm, weight 126 kg/km.

· Excellent Mechanical Performance: Long-term tension 1500N; short-term tension 4500N; long-term crush 300N, short-term crush 1000N.

· Durable Weather Resistance: Anti-UV, salt spray and aging; service life over 30 years.
