Water blocking tape longitudinal package prevents longitudinal water seepage of optical cable
Two parallel steel wires ensure the tensile strength of the optical cable
Outdoor optical cables have greater tensile strength, thicker protective layers, dan biasanya berperisai (itu dia, sarung logam). Outdoor optical cables are mainly suitable for interconnection between buildings and remote networks.
Secara amnya, outdoor optical cables are only used as fillers, reinforcing members, and sheaths. For example, when outdoor optical cables are buried directly, armored optical cables should be used. When overhead, you can choose a black plastic outer fiber optic cable with two or more reinforcing ribs.
Outdoor fiber optic cable must be waterproof because it is used outdoors. Secara amnya, the outer sheath is made of PE material, and then its internal structure is generally divided into a central tube structure and a stranded structure.
From the naked eye, the indoor and outdoor sheaths are generally yellow or orange PVC material, and the outdoor PE sheaths are black. The difference between the models is generally the word GY.
Kabel optik luaran: The outer package is thick and has some mechanical and environmental characteristics such as pressure resistance, corrosion resistance and tensile strength.
Indoor fiber optic cable: It is mainly used indoors. The main feature is to be flexible, and it can be used in narrow places such as corners. Kedua, it has external characteristics such as fire resistance, flame resistance, tensile strength, and softness.
Outdoor optical cable is a communication line that completes optical signal transmission. A certain number of optical fibers are used to form a cable core, which is sheathed outside and some are covered with an outer sheath.
Outdoor optical cable is mainly composed of optical fiber (thin glass fiber as thin as hair) and plastic maintenance tube and plastic sheath. There is no metal such as gold, perak, tembaga dan aluminium dalam kabel optik.
