In recent years, with the development of the optical information industry and related promotion, FTTH (Fiber to the Home) has been the solution model for the recent development of access networks. It adapts to the development of technology in the optical field, and is also in line with users of high-speed and large-capacity optical network signals. Transmission requirements. In the large-capacity FTTH access project, the mechanical bending performance and tensile performance of conventional indoor optical cables can no longer meet the requirements of FTTH (fiber to the home) indoor cabling. In the case of market demand, high-strength, low bend radius leather fiber optic cables have appeared, which will be widely used in FTTH (Fiber to the Home) access networks.
The maximum transmission distance of the drop cable can reach 70 kilometers. However, generally, the construction part covers the fiber optic backbone to the door of the house and then decodes it through the optical transceiver. However, if a one-kilometer project is done with a leather cord, it must be an external project. The leather cord itself is too fragile, so it is very easy to break and its strength is not that great.
Due to its softness and lightness, drop cable is widely used in access network. The scientific name of the drop cable is the butterfly-shaped entry cable for the access network; It is also called a butterfly because of its shape. Form the optical cable and the optical cable into an 8 shape.
Covered cable: It is a bend-resistant optical fiber, which can provide higher bandwidth to improve network transmission performance; With two parallel FRP or metal reinforcements, the optical cable has good compression resistance to protect the optical fiber; The optical cable has a simple structure and light weight, and strong practicality; It has unique groove design, easy to take off, can be convenient to splice.
If it is single-mode, it can be further away, but if the one-kilometer project is done with leather cable, it must be an external line project, so it is felt that the leather cable is too fragile, it is very easy to break and have no strength. So big.
