The Fiber Optic Splice Closure and its related accessories have detailed knowledge to understand the basic knowledge of various optical fiber cables and their devices. For FTTH optical cable, you are sure that you are aware of it. It is correct that the name suggests is an optical fiber directly to the home. In detail, FTTH refers to the installation of optical network units (ONUs) at home users or enterprise users. It is the optical access network application type that is the closest to users except for FTTD (Fiber to the Desktop) in the optical access series. In general, the fiber optic splice closures we will use require fiber optic cables for connection.
So do you know why we use fiber optics and fiber optic splice closures? Fiber optic cable FTTH is a passive network, from the central office to the user, basically can be done in the middle of the passive. Second, its bandwidth is relatively wide, and the long distance is exactly in line with the large-scale use of operators. Because it is a service carried on fiber, there is no problem.
Indoor fiber optic cable is classified according to the environment in which the fiber optic cable is used, in contrast to the outdoor fiber optic cable. The indoor cable is a cable formed by an optical fiber (optical transmission carrier) through a certain process. Mainly by the optical fiber (fine as hair glass filaments) and plastic protective sleeve and plastic skin composition, there is no gold, silver, copper and aluminum and other metals in the cable, generally no recovery value. Indoor fiber optic cable is a certain number of optical fibers in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer sheath, a type of communication line used to achieve optical signal transmission. Indoor cable has low tensile strength and poor protection, but it is also lighter and more economical. Indoor fiber optic cable is mainly used for wiring inside buildings and connections between network devices.
Outdoor cable is a kind of communication line that realizes optical signal transmission. A certain number of optical fibers form a cable core in a certain way and are sheathed, and some also cover the outer sheath. Outdoor cable is mainly composed of optical fiber (fine as the glass fiber of hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the cable, generally no recovery value. Outdoor optical cables have higher tensile strength, thicker protective layers, and are generally armored (ie, metal sheaths). Outdoor cable is mainly used for interconnection between buildings and between remote networks.
