Ind-Simplex Bow Type G657A1 Drop Wire Fiber Optic 2 Coretype single
mode duct drop cable communication wire Telecommunication network
The butterfly-shaped optical fiber cable is to place the optical
fiber in the center, place two parallel FRP wires on both sides as
reinforcing elements, and extrude a low-smoke halogen-free
flame-retardant sheath. Reinforcing member ( FRP) is placed on each
side of the groove, coating with PE(LSZH,PVC) jacket.
Structure:
- Bow-tie type cross-section design
- two parrallel FRP wire as strength member
- G657A1 flex durable fiber in the middle
- Reinforcing member ( FRP) is placed on each side of the groove
- PE or LSZH outer jacket
Feature
1. Special bending-resistant optical fiber, providing greater
bandwidth and enhancing network transmission performance;
2. Two parallel FRP or metal 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.
