Self-supporting optical fiber cable is a kind of optical cable product that is different from other ordinary optical cables in structure. The wall-mounted method is introduced to the indoor optical cable. When the leather-wire optical cable is turned and installed, it is necessary to pay attention not to bend it excessively to avoid causing breakage and affecting the service life.
Secondly, during the installation process, it needs to be tied firmly, so as to avoid external dynamic stress, and the internal stress of the steel wire will cause the support to loosen and fall off. The type of leather cable used needs to be adapted to the environment to avoid some unnecessary accidents.
The self-supporting optical fiber cable adds a thick steel wire hanging wire to the structure of the ordinary optical fiber cable. Generally speaking, the self-supporting optical fiber cable just has one more steel wire, and the others remain unchanged. The structure of each manufacturer of leather cable is basically different. However, they are generally not metal reinforced cores, such as butterfly-shaped leather cable. The shape of the cross section is like a butterfly, the side is the reinforcement in the leather wire, and the middle is the optical fiber.
Under normal circumstances, the sheath material of the sheathed optical cable we choose needs to meet the requirements of GB/T 8815 HR-70 "70 ℃ soft sheath grade soft polyvinyl chloride plastic"; however, for flame retardant polyethylene sheath For optical cables, the sheath material should comply with the regulations of YD/T 1113; in addition, the surface of the sheath of the self-supporting leather cable should be flat and smooth, and there should be no visible cracks, bubbles and blisters on the section. It can be continuously extruded on the optical fiber and the strengthening member.
Every product has a selection standard, and the leather cable is no exception, so the above is its selection standard.
Application scenarios of leather fiber optic cable
Through the introduction of ZR Fiber, I believe that everyone has some understanding of the standards for the selection of self-supporting fiber optic cable sheath materials. If you want to know more about ZR fiber jumper products, welcome customers to come and consult.
