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(or non-metallic) central strength member to form a cable core. The core is armored with a layer of fire resistance tape and corrugated steel tape. Then a LSZH inner sheath is extruded and armored with another layer of fire resistance tape and corrugated steel tape. Finally, a LSZH outer sheath is extruded.
• Accurate process control ensuring good mechanical and temperature performances
• The material of loose tubes with good hydrolysis resistance and relatively high strength
• Fire-resistant layers and LSZH sheaths ensuring good fire resistance and flame-retardant performances
• Excellent crush resistance
• Comply with IEC60331(no cooling), IEC60754-1&2, IEC61034 and IEC60332-2-24
• Standard length: 2,000m; other lengths are also available.
