With the development of fiber optic communication, FTTH has been the final solution of fiber-optic networks. It adapts to the demand for high speed and massive transmission of optical network signals from many users. In FTTH access projects, common indoor fiber optic cable cannot meet the requests of indoor distribution in mechanical ability and tensile properties. Under the situation of the market’s needs, FTTH drop cable with low bending radius and high intensity has been widely used in FTTH’s access network.
Cable Structure:
The optical fiber unit is positioned in the center. Two parallel strength members are placed at two sides. Then, the cable is completed with a jacket.
Features:
- Low purchasing and construction costs
- Soft and flexible, good bending performance
- Simple structure, compact and lightweight, and high practicability
- Flame retardant LSZH jacket meets relevant fire protection requirements in the indoor environment
- Two parallel strength members ensure good performance of crush resistance to protect the fiber
- Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property
- Novel notch design for easy stripping, and easy connection without splicing or with splicing, simplify the installation and maintenance
Applications:
- FTTx FTTH project for indoor cable
- Installation in a small bending environment
