Description
6C,8C,12C Butterfly flat FTTH drop cable uses butterfly flat structure. To construct the cable，Max 12pcs of SM G657A1 or G657A2 optical fiber units are positioned in the center. Two parallel Fiber Reinforced Plastic (FRP) rods are placed diametrically opposite on either side of the fiber core. The strength member rods and fiber core are then encapsulated in a durable LSZH jacket to create a flat cable cross section and lend added protection to the cable core.
This FTTH Indoor Drop Cable is designed for in-home fiber installations.
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
- Fibers count is 1-12 cores, can be other fiber cores upon request.
- Novel flute design, easily strip and splice, simplify the installation and maintenance
- Low smoke, zero halogen and flame retardant sheath
