Product application：
GYTS outdoor loose tube layer-stranded type optical cable (steel strip longitudinal wrap) is applied to remote and interoffice communication; laying mode: pipe laying and overhead laying.
Application standard：
ISO/IEC 11801：2008、YD/T901-2009
Product Features：
1. Small transmission loss and low chromatic dispersion.
2. Excellent mechanical properties and has good capability of resisting bending.
3. 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.
4. The loose tube filled with gel and can make ensure the fiber transmission stability for long time.
5. 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 ensured.
6. 9/125 single-mode fiber, 50/125 multimode fiber, 62.5/125 multimode fiber and OM1, OM2, OM3 multimode fibers can be chosen.
Application standard: ISO/IEC 11801：2008、YD/T901-2009
