Central strength member (CSM): steel wire material or steel wire Coated PE material if need
Tube: Thermoplastic material, containing up to 12 optical fibres fil ed with a low viscosity, thixotropic, non-melting gel ful y compatible with fibre coating and tube material
Stranding: The required numbers of elements (tubes and fil ers) are SZ stranded around the central strength member
Reinforcing: FRP
Sheath: UV stabilised polyethylene in And coated Nylon with heavy rodent resistance
Direct Buried, Outdoor, Underground
• 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
• Combination of physical and chemical anti-rodent methods
• Flat FRP armor providing the physical anti-rodent performance
• Anti-rodent sheath providing the chemical anti-rodent performance, which effectively delays the diffusion of anti-rodent additives to protect working environment and construction safety
• All-dielectric design, applicable to lightning-prone areas
• Applicable to aerial and duct installations with anti-rodent and anti-lightning requirements.
