Product application：
GYTA53 outdoor direct burial loose tube layer-stranded type optical cable (double-layer metal strip longitudinal wrap) is applied to remote and interoffice communication; laying mode: direct burial.
Application standard：
ISO/IEC 11801：2008、YD/T901-2009
Product Features：
1.Small transmission loss and low chromatic dispersion.
2.Excellent mechanical properties and environmental performances due to reasonable design and precision control of the redundant length and the cabling method of the optical fiber in the loose tube.
3. The loose tube filled with gel and can make ensure the fiber transmission stability for long time.
4. The parts outside the reinforcing member and in the cable conductor are full of water-blocking cable paste; therefore the damp-proof and water-blocking effects of the optical cable can be ensure
5. Good flexibility and capability of resisting bending.
6. Double-layer metal strip longitudinal wrap has the ability of preventing the optical cable from damage of rodent due to strong resistance to tension and strong resistance to lateral pressure of the double-layer sheath.
7. 9/125 single-mode fiber, 50/125 multimode fiber, 62.5/125 multimode fiber and OM1, OM2, OM3 multimode fibers are available.
