Fiber Optic Cable
Optical fiber cable (optical fiber cable) is manufactured to meet the optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a coated jacket as a transmission medium and can be used individually or in groups. Cable assembly. The optical cable is mainly composed of optical fiber (glass fiber as thin as hair) and plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally there is no recycling value. An optical cable is a certain number of optical fibers composed of a cable core in a certain way, which is covered with a jacket, and some is also covered with an outer sheath, which is a communication line used to realize optical signal transmission. That is: a cable formed by an optical fiber (optical transmission carrier) after a certain process. The basic structure of an optical cable is generally composed of a cable core, reinforced steel wire, filler, and sheath. In addition, there are other components such as a waterproof layer, a buffer layer, and insulated metal wires as needed.
Basic Structure
The optical cable is composed of a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are other components such as a waterproof layer, a buffer layer, and insulated metal wires as needed.
The optical cable is composed of a reinforced core and a cable core, a sheath and an outer sheath. There are two types of cable core structure: single-core type and multi-core type: single-core type has two types: full type and tube bundle type; multi-core type has two types: ribbon and unit type. The outer sheath has two types of metal armor and non-armor.
Fiber Inspection
The main purpose of optical fiber inspection is to ensure the quality of the system connection, reduce the fault factors and find the fault point of the fiber when the fault occurs. There are many detection methods, mainly divided into manual simple measurement and precision instrument measurement.
1. Manual simple measurement
This method is generally used to quickly detect the on and off of the optical fiber and to distinguish the optical fiber made during construction. It uses a simple light source to enter visible light from one end of the fiber and observe which one emits light from the other end. Although this method is simple, it cannot quantitatively measure fiber attenuation and fiber breakpoints.
2. Precision instrument measurement
Using an optical power meter or an optical time domain reflectometer (OTDR) to quantitatively measure the fiber, you can measure the attenuation of the fiber and the attenuation of the connector, and even the position of the fiber breakpoint. This measurement can be used to quantitatively analyze the causes of fiber network failures and evaluate fiber network products.
Type of Optical Cable
1. According to different transmission performance, distance and use, optical cables can be divided into user optical cables, local telephone optical cables, long-distance optical cables and submarine optical cables.
2. According to different types of optical fibers used in optical cables, optical cables can be divided into single-mode optical cables and multi-mode optical cables.
3. According to the number of optical fiber cores in the optical cable, the optical cable can be divided into single-core optical cable and dual-core optical cable.
4. According to different configuration methods of reinforcements, optical cables can be divided into central reinforcing member optical cables, dispersed reinforcing member optical cables, sheath reinforcing member optical cables and integrated outer sheath optical cables.
5. According to different transmission conductors and medium conditions, optical cables can be divided into metal-free optical cables, ordinary optical cables, and integrated optical cables (mainly used for railway dedicated network communication lines).
6. According to different laying methods, optical cables can be divided into pipeline optical cables, direct buried optical cables, overhead optical cables and underwater optical cables.
7. According to different structural methods, optical cables can be divided into flat-structure optical cables, stranded optical cables, skeleton optical cables, armored optical cables and high-density user optical cables.
Identify the Advantages And Disadvantages
Generally identify the quality of the optical cable from the following aspects:
1, outer skin; 2, optical fiber; 3, reinforced steel wire; 4, steel armor; 5, loose tube; 6, grease; 7, aramid; 8, water blocking tape;
