Product application：
The butterfly optical cable is the novel user access optical cable which combines the characteristies of the indoor soft optical cable and the self-supporting optical cable together, it is the best altemative choice for solving the problems of FTTX network and plays the unique role in building networks, such as the intelligent building, the digital district, the campus network and the local area network
Application standard：
YD/T1997.1-2014
Product Features：
1.Poor rigidity, but excellent flexibility
2.Strong tensile strength, which is useful for self-supporting overhead laying and traction laying of the vertical pipe. the optical cable can be laid by the shaft and channel of the building available and laid directly on the outer wall of the building
3.It can be connected with the joint box without introduction of sensing current.
4.The reinforcing member can be non-metal FRP and KFRE(optional)
5.The outer sheaths prepared from low-smoke halogen-free material and the flame-retardant polyvinyl chloride are available.
6.Operation temperature -20C°C ~ +60°C
