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 the high-speed and large-capacity users of 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 wiring. In the case of market demand, low-bending radius, high-strength 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, in general, the construction party covers the optical fiber 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 cable, it should be an external project. The leather cable itself is too fragile, so it is very easy to break, and its strength is not that great.
Because of its softness and lightness, the drop cable is widely used in the access network. The scientific name of the drop cable is the butterfly-shaped lead-in cable for the access network; it is also called butterfly because of its shape. Shape optical cable, and figure 8 optical cable.
Covered cable: It is a bending-resistant optical fiber, which can provide greater bandwidth to enhance 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 practicability; has a unique groove design, easy to peel off, can be convenient for splicing.
If it is single-mode, it can be farther away, but if the one-kilometer project is done with a leather cable, it should be an external line project, so does it feel that the leather cable is too fragile, it is very easy to break, and it has no strength So big.
