Structure Design
Description
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.
Application
1. Used as access building cable in premises distribution system, especially used in indoor or outdoor aerial access cabling.
2. Adopted to core network;
3. access network, fiber to the home;
4. Building to building installation;
Features
1. Fiber type: ITU-T- G652D, G657A fiber, G657B fiber
2. It has good mechanical and environmental performance
3. Flame (or not flame retardant) performance to meet the requirements of the standard
4. Mechanical and physical properties of the sheath to meet the relevant standards Soft, flexible and convenient
5. Good structure design, easy for branching and splicing
6. Small size and light weight, easy for installation
7. LSZH sheath ensuring good flame-retardant performance
8. Especially applicable to vertical wiring in buildings
