Outdoor underground double armored double sheath stranded loose tube direct buried fibre optic cable
In the GYTY53 cable,single-mode/multimode fibres are positioned in the loose tubes,which are made of high modulus plastic materials,while the loose tubes strand together around metallic central strength member into a compact and circular cable core.For certain high fibre count cables,the strength member would be covered with polyethylene PE.The water-blocking materials are distributed into interstices of the cable core.The cable core is covered with a PE inner sheath,and the PSP is longitudinally applied around the cable core before a PE outer sheath is extruded over it.
· Excellent mechanical and temperature performance guaranteed by the accurate excess fibre length
· Critical protection to fibres,based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube
· Excellent crush resistance and flexibility
· The following measures are taken to ensure the water blocking performance of the cable,single steel wire used as the central strength member,special water-blocking filling compound material in the loose tube,100% cable core filling,PSP moisture barrier,water-blocking material.
