GYTA53 Direct Burial Stranded 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: 2~228
♦ Low loss, low dispersion
♦ Proper design and precise excess length control offer excellent mechanical and environmental properties to cable
♦ Double sheath enhances the cable's side pressure resistance and moisture proof property
♦ Small size, light weight, easy to install
♦ The sheath can be made of LSZH material. (The model turns to GYTZA53 in the case)
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
