Description
All Dielectric Flat Drop cable is a high tensile FTTH drop cable with an oval flat structure. Two parallel Fiber Reinforced Plastic (FRP) strength members are placed on the two sides. Its optical fiber unit is positioned in the center Losse tube (made of PBT materials). Then, the cable is completed with a PE sheath.
Feature
- Good waterproof performance
- Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property
- Two parallel FRP strength members ensure good performance of crush resistance to protect the fiber
- Simple structure, light weight and high practicability
- Novel flute design, easily strip and splice, simplify the installation and maintenance
- Low smoke, zero halogen and flame-retardant sheath
