  • What are the advantages of optical fiber

    Optical fiber communication is a modern form of communication that uses high-frequency light waves as the carrier wave and optical fiber as the transmission medium to send information point by point. It has many advantages. Compared with traditional communication transmission methods, the advantages of optical fiber transmission are reflected in the following aspects: 1. Broader bandwidth: the storage capacity of data information is large. The bandwidth of optical fiber data information is larger. Compared with conventional copper wire and other types of cables, the bandwidth is larger. Optical fiber has a higher bandwidth in the process of data information transmission. Light source adjustment performance, diversified adjustment methods, and fiber itself has strong dispersion performance. From the perspective of single-wavelength optical…

  • Main types of optical fiber

    1. Quartz optical fiber: Quartz (glass) series optical fiber, which has the characteristics of low consumption and broadband, has been widely used in cable television and communication systems. 2. Infrared fiber: As the working wavelength of the quartz series fiber developed in the field of optical communication, although it is used in a shorter transmission distance, it can only be used in 2μm. Infrared optical fiber is mainly used for light energy transmission, such as: temperature measurement, thermal image transmission, laser scalpel medical treatment, და ა.შ.. 3. Composite optical fiber: Multi-component glass has a lower softening point than silica glass and a large difference in refractive index between the core and the cladding. It is mainly used in optical fiber endoscopes…

  • Features of outdoor optical cable

    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, 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…

  • What is the difference between indoor fiber optic cable and outdoor fiber optic cable

    1. According to different natural environments, optical cables are divided into indoor optical cables and outdoor optical cables. The center of the fiber optic cable is an optical fiber, and the center of the optical fiber is usually a glass core. The core is surrounded by a glass shell with a lower refractive index than the core, so the optical signal entering the core is reflected by the cladding interface, allowing the light to pass through the core. Because the optical fiber itself is very fragile and cannot be directly applied to the wiring system, the optical fiber bundle is usually bundled with the outer protective layer and the middle tension wire. This is the so-called optical cable, which usually…

  • What are the differences between fiber and cable

    1. Optical fiber is a thin and soft medium that transmits light beams. Most optical fibers must be covered by several layers of protective structures before use. The coated cable is called an optical cable. Therefore, the optical fiber is the core part of the optical cable, and the optical fiber is formed by the protection of some components and the auxiliary protective layer. The protective structure of the outer layer of the optical fiber can prevent the surrounding environment from damaging the optical fiber. The optical cable includes an optical fiber, buffer layer, and cladding. Optical fiber is similar to coaxial cable except that it does not have a mesh shield. At the center is the glass core for…

  • Learn more about fiber optic cable, terminal box, pigtail connection and various fiber interfaces

    In network cabling, fiber optic cables are usually used for connection between outdoor buildings, and optical fibers or network cables are used inside indoor buildings. So how to convert between the optical cable transmission medium outside the building and the Ethernet transmission medium inside the building? What equipment was used in it? What is their role? What about the relationship between them? Pigtail: used in the terminal box to connect the optical fiber in the optical cable, and connect the pigtail and the jumper through the terminal box coupler (adapter). Jumper: Both ends of the fiber jumper are movable connectors, which serve to connect the fiber jumper and the device. Optical cable terminal box: It is a box where the…

  • What is aerial fiber

    Overhead aerial fiber is an optical cable used for hanging on a pole. This way of laying can use the existing overhead open-line pole road, saving construction costs, and shortening the construction period. The overhead optical cable is hung on the electric pole and is required to be able to adapt to various natural environments. Overhead optical cables are susceptible to the threats of natural disasters such as typhoons, icicles, floods, etc., and are also susceptible to external forces and weakening of their own mechanical strength. Therefore, the failure rate of overhead optical cables is higher than that of direct buried and pipeline fiber optic cables. Generally used for long-distance Class 2 or below lines, suitable for dedicated network optical…

  • Classification of outdoor optical cable

    According to the transmission mode of optical fiber, it is divided into single mode fiber and multimode fiber Single-mode fiber This refers to the optical fiber that can only transmit one propagation mode in the operating wavelength, usually referred to as single-mode fiber (SMF: Single-Mode Fiber). In cable TV and optical communication, it is the most widely used optical fiber. Because the core of the optical fiber is very thin (about 10 μm) and the refractive index is distributed stepwise, when the normalized frequency V parameter <2.4, theoretically, only single-mode transmission can be formed. In addition, SMF does not have multi-mode dispersion. Not only does the transmission band have more modes and the fiber is wider, but the addition of…
