Product application：
GYXTW outdoor miniature central beam tube typefiber optical cable is applied to remote and interoffice communication; laying mode: pipe and overhead laying.
Application standard：
ISO/IEC 11801：2008、YD/T769-2010
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 of the optical fiber in the loose tube.
3. Compact structure; and the optical fiber is ensured not to be subjected to the stress when the optical cable is taken in the rugged environment due to the structure of central loose tube.
4. The part in the cable conductor is full of water-proof cable paste; therefore the damp-proof and water-blocking effects of the optical cable can be ensured.
5. Good flexibility and capability of resisting bending.
6. 9/125 single-mode fiber, 50/125 multimode fiber, 62.5/125 multimode fiber and OM1, OM2, OM3 multimode fibers are available.
