Micro Tube Indoor Outdoor Drop Fiber optic Cable is a popular fiber cable in the market. The drop fiber cable uses multiple 900um flame-retardant tight buffer fibers as optical communication medium, two parallel Fiber Reinforced Plastic (FRP) are placed at the two sides as strength member, then the cable is completed with a flame-retardant LSZH (low smoke, zero halogen, flame-retardant) jacket.
Features
- Fiber type: ITU-T- G652D, G657A fiber, G657B fiber
- It has good mechanical and environmental performance
- Flame (or not flame retardant) performance to meet the requirements of the standard
- Mechanical and physical properties of the sheath to meet the relevant standards Soft, flexible and convenient
- Good structure design, easy for branching and splicing
- Small size and light weight, easy for installation
- LSZH sheath ensuring good flame-retardant performance
- Especially applicable to vertical wiring in buildings
Application
- Used as access building cable in premises distribution system, especially used in indoor or outdoor aerial access cabling.
- Adopted to core network;
- access network, fiber to the home;
- Building to building installation
