Optical Fibre Drop Cable
The optical fibre drop cable is primarily utilized for FTTH (fiber to the home) and FTTB (fiber to the building) applications. It is divided into two series according to its strength member: GJXH refers to ones with steel wires, while GJXFH refers to ones with FRP.
Structure
A single tube containing 1/2/4 fibers is positioned at the center, and two diametrically opposed strength members (steel wire or FRP) are placed alongside the buffer tube. Then, a LSZH jacket is applied.

Fiber Type
1. Single mode fiber optic cable: G.652 or G.657 fiber
2. Multimode fiber optic cable: 50/125 or 62.5/125 fiber
Characteristic
1. Our indoor optical drop cable makes use of conventional single or multi mode fibers, and its jacket can be removed in a rapid and easy way.
2. For the GJXH flat drop cable, it adopts metallic strength members, so it has higher crush resistance. On the other hand, the GJXFH flat drop cable has an all-dielectric structure, so shielding box is not required.
