GYTC8S Self-supporting Aerial Optical Cable
Technical Characteristics
Structure description: Jelly filled loose tube (and PP filler) stranded together around the metallic strength member, protected by peripheral strength member (Corrugated steel tape armor) and HDPE sheath.
♦ Fiber count: 2~288
♦ Low loss, low dispersion
♦ Proper design and precise excess length control offer excellent mechanical and environmental properties to cable
♦ Courrugated steel tape armor brings better humidity proof performance and side pressure resistance
♦ Compact construction, light weight, self-supporting installation
Performance
♦ Applicable to long distance, inter-exchange communication, CATV, computer network transmission system, etc.
♦ Minimum bend radius: static 10D, Dynamic 20D
♦ Operation temperature: -40 ~ +70
