Let everyone enjoy the freedom and happiness brought by optical fiber technology
Outdoor optical cables are simply one type of optical cables used outdoors. They are called outdoor optical cables because they are most suitable for outdoor use. They are durable and can withstand wind, sun and cold, and have a thick outer packaging. , It has some mechanical and environmental characteristics such as pressure resistance, corrosion resistance and tensile resistance.
The water-blocking tape is longitudinally wrapped to prevent the longitudinal water seepage of the optical cable
Two parallel steel wires ensure the tensile strength of the optical cable
Outdoor fiber optic cables have higher tensile strength, a thicker protective layer, and are usually armored (that is, metal sheathed). Outdoor optical cables are mainly suitable for interconnection between buildings and between remote networks.
Generally speaking, outdoor optical cables are just fillers, strengthening members, sheaths and other materials are selected. For example, when the outdoor optical cable is directly buried, armored optical cable should be used. When overhead, an optical cable with a black plastic outer sheath with two or more reinforcing ribs can be used.
Because the outdoor optical cable is used outdoors, it must have a waterproof function. Generally, the outer sheath used is made of PE material, and its internal structure is generally divided into a central tube structure and a layered structure.
From the naked eye, the indoor and outdoor jackets are generally yellow or orange PVC materials, and the outdoor ones are black PE jackets. Different from the model, the outdoor jacket generally has the word GY.
Outdoor optical cable: The outer package is thick, with some mechanical and environmental characteristics such as pressure resistance, corrosion resistance, and tensile resistance.
Indoor optical cable: Mainly used indoors, the main feature should be easy to bend, can be used in narrow places such as corners, and secondly have external features such as fire resistance, flame retardancy, tensile strength, and flexibility.
Outdoor optical cable is a communication line that completes optical signal transmission. The cable core is composed of a certain number of optical fibers in a certain manner, and is covered with a sheath, and some are also covered with an outer sheath.
Outdoor optical cables are mainly composed of optical fibers (thin glass filaments such as hair), plastic maintenance sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cables.
