- All-dry GYFZY Fire-resistance Stranded Loose Tube Optical Cable
- 【Brief】：
- 【Series】：Mining fiber optic cable
Description
Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with water blocking yarns. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is amored with a layer of fire resistance tape and glass fibre yarns. Then, a LSZH outer sheath is extruded.
Feature
• All-dry design improving efficiency of construction and splicing
• Light weight, easy for long distance installation
• Accurate process control ensuring good mechanical and temperature performances
• All-dielectric design, applicable to lightning-prone areas
• Fire-resistant layer and LSZH sheath ensuring good fire resistance and flame-retardant performances
• Applicable to duct, aerial and vertical installations
