Description 

GYFTY73 is designed with physical anti-rodent measure. Single-mode/multimode fibres are housed in loose tubes that are made of high-modulus plastic. The tubes are stranded around a central strength member to form a cable core. The core is filled with cable filling compound. Then an inner PE sheath is extruded and armored with FRP tape. Finally, a PE outer sheath is extruded.

Features
• Physical anti-rodent method, green and environment-friendly
• Accurate process control ensuring good mechanical and temperature performances
• The material of loose tubes with good hydrolysis resistance and relatively high strength
• Tube filling compound providing key protection for fibres
• FRP tape armor providing good anti-rodent performance
• All-dielectric design, applicable to lightning-prone areas
• Applicable to aerial and duct installations with anti-rodent and anti-lightning requirements
