4 Core G657A Outdoor Fiber Optic FTTH Drop Cable
Most of the fiber optic drop cables are single-core and double-core structures, and can also be made into a four-core structure and above. The cross-section is an eight-shaped structure. The reinforcement is located in the center of the two circles. The metal or non-metallic structure can be used. . G.657 small bending radius optical fiber is used for the optical fiber in the sheathed cable, which can be laid with a bending radius of 20mm, which is suitable for entering the house in the way of the pipeline or the bum line.

Construction Method
In the FTTX project, large-scale use of covered optical fiber cables mainly uses two connection methods: one is cold connection technology (physical connection) based on cold connectors, and the other is hot fusion technology using fusion splicers as tools.
Cold connection technology
Cold splicing technology: The optical fiber cold splice is used when two pigtails are connected. The main component inside it is a precision v-shaped groove. After the two pigtails are pulled, the cold splice is used to realize the connection of the two pigtails. It is simpler and faster to operate, saving time than welding with a welding machine.
On the surface, the cold splicing operation is simple and fast, which saves time compared to the hot welding of the splicer. However, the cold splicing technology is also mainly used in emergency applications after the communication of the optical cable is interrupted.
Hot melt technology
1. Small welding loss. The two optical fibers adopt hot-melt technology, and the fusion is carried out according to the trunk standard, which greatly reduces the fusion loss.
2. Long service life and low maintenance cost. Since the hot-melt standard is required according to the construction of the main line, the life of the general welding point will be similar to that of the ordinary optical cable, and there is no problem of the life of a single point.
