Optical data cable GYFTA54

audio/videoRFarmored

GYFTA54 is a kind of outdoor communication optical cable, which consists of a non-metallic central strength member, stranded loose tubes, a laminated aluminum tape armor, a PE inner sheath, a stainless steel tape armor, a PE middle sheath and a nylon outer sheath. Single-mode fibres are housed in loose tubes that are made of highmodulus plastic and filled with tube filling compound. The tubes are stranded around the central member to form a cable core. The core is filled with cable filling compound and armored with laminated aluminum tape. Then a PE inner sheath is extruded and armored with stainless steel tape. Finally, a middle PE sheath and a nylon 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 • Tube filling compound providing key protection for fibres • Excellent crush resistance • Metallic armors providing good anti-rodent performance • Nylon outer sheath with high hardness providing certain anti-termite performance • Applicable to duct and buried installations 1. Xn refers to fibre type. For details, see naming rules for optical cables of YOFC. 2. For color arrangement of fibres and loose tubes, see the color sequence. 3. D is cable diameter. • Standard length: 2,000m; other lengths are also available
