Fabrication Method Of Closed Structure Of Fiber Optic Splice Clsoure
Regardless of the structure of the cable, it must have a device, for example, that connects a transmission medium at one end of a given length cable to the corresponding transmission medium at the adjacent end of another length of cable. Usually, a closed structure is used, in which all conductors are connected, wound and stored, and for environmental protection.
During the connection of a metal conductor, it is customary to bend the conductor significantly to provide access to other connections. The physical properties of glass fibers impede the use of the connection technology used in the metal conductors of this closed structure. If the fiber is bent over the permissible bending radius and the light is no longer fully contained in the core of the fiber, the transmission capacity may be weakened.Fiber Optic Splice Clsoure
In addition, there is a need for a closed structure that is particularly suitable for the use of loop fiber requirements and for joining some of the relatively small number of optical cables called drop or drop cables. The drop cable is the optical cable that extends from the street distribution to the house. For such applications, what is needed is a fairly inexpensive closed structure to meet this potentially large market demand. Furthermore, the desired closure structure is best in size to be very small to accommodate the appropriate number of loop fiber connectors. As expected, existing technologies have a ready-made optical fiber closure structure. Some of these existing technologies have drawbacks in the case of the application of the loop fiber market.Fiber Optic Splice Clsoure
When optical fibres are bonded through a mechanical device or through a melt, a fiber that is sufficiently slack in the existing technology closure structure allows the optical fiber to be pulled out of the closed structure and placed in a device for preparing the fiber terminals and connecting them together. When the closed structure is sealed, that is, when the jointing process is completed, the optical fiber of each optical cable is generally required to be at least 0.5 m contained in the joint closure structure.
In such a device, it is necessary to have a method of storing the relaxation portion of the curvature of the minimum bending radius of a fiber not less than approximately 3.7 to 5cm to protect the joint and to keep the fiber in an orderly manner.Fiber Optic Splice Clsoure
In another closed structure, a tubular shell with a closed end and an open end is suitable for accepting and sealing the cable terminal assembly. The optical cable terminal assembly includes a fiber optic cable entry device, through which the device chooses the route for the cable to be joined. A supporting piece is extended from the optical cable inlet device and has a free end set on the closed end of the adjacent enclosure. The support comprises a support seat for supporting a fiber optic branch joint and a set of fiber connector trays.
