There are many classifications of optical cables. Outdoor optical cables, as the name suggests, are generally suitable for outdoor use. So what are the special features of outdoor optical cables? Let’s take a look.
1. Outdoor optical cables have high tensile strength, thick and heavy protective layer, e geralmente são blindados (isso é, bainha de metal). Cabos ópticos externos são principalmente adequados para interconexão entre edifícios e entre redes remotas. Generally speaking, outdoor optical cables are just fillers, strengthening members, sheaths and other materials are selected. Por exemplo, 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.
2 Because the outdoor optical cable is used outdoors, it must have a waterproof function. Geralmente, 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.
3. Cabo óptico externo: The outer packaging is thick, with some mechanical characteristics such as pressure resistance, corrosion resistance, and tensile strength. Outdoor optical cable is a communication line that completes the transmission of optical signals. The cable core is composed of a certain number of optical fibers in a certain manner, e é coberto com uma bainha, e alguns também são cobertos com uma bainha externa. Outdoor optical cables are mainly composed of optical fibers (thin glass filaments like hair), plastic maintenance sleeves and plastic sheaths. Não existem metais como ouro, prata, copper and aluminum in the optical cables.
