The 250um colored coating fiber is positioned in the centre. Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides. The cable is completed with a black or color UV and flame resistant LSZH sheath.
Structure:
- Bow-tie type cross-section design
- two parrallel FRP wire as strength member
- G657A1/A2 flex durable fiber in the middle
- PE or LSZH outer sheath
Feature:
- Good UV and flame resistant.
- Bow type flat structure.
- Compact, soft, flexible, easy to install.
1. Special bending-resistant optical fiber, providing greater bandwidth and enhancing network transmission performance;
2. Two parallel FRP reinforcements make the optical cable have good pressure resistance and protect the optical fiber;
3. The optical cable has simple structure, light weight and strong practicability;
4. Unique groove design, easy to peel, easy to connect, simplify installation and maintenance;
5. Low-smoke halogen-free flame-retardant polyethylene sheath or flame-retardant PVC sheath, environmental protection.
6. Can be matched with a variety of on-site connectors, can be on-site end.
7. Because of its softness and lightness, the sheathed cable is widely used in the access network; the scientific name of the sheathed cable is that the access network uses a butterfly to introduce the optical cable; because its shape is a butterfly, it is also called a butterfly Optical cable, 8-shaped optical cable.
