Ducting waiver® Sewer Optical Cable (GPTCA63)

It is a kind of self-supporting optical cable for laying in storm sewers. Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a metallic central strength member to form a cable core. The core is filled with water blocking compound and armored with laminated aluminum tape . Then a PE inner sheath is extruded and aramid yarns are placed outside the inner sheath as the strength member, Finally, a PE outer sheath is extruded.
Features

• 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
• Excellent crush resistance and flexibility
• Water resistance of optical cable is ensured by the following measures: 
• Special water blocking compound filled in loose tubes
• Laminated aluminum tape armor
• Cable filling compound ensuring longitudinal water resistance
