  • 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…

  • Indoor Fiber Optic Science

    As the name implies, indoor fiber cables are generally suitable for indoor scenes. Because they are generally used indoors, they do not require a waterproof structure. Therefore, indoor optical cables have good flexibility, high bending performance, fast transmission speed, stable and clear signals, and strong anti-interference. , Large transmission flow, light, and economic advantages Structure of indoor optical cable 1. The indoor optical cable has good flexibility and fine density, the outer skin is orange and yellow, and the optical fiber is wrapped with a tight sleeve. 2. Indoor optical cables are usually selected for making optical fiber jumpers, computer room wiring, and building indoor network wiring. 3. Aramid yarn is mostly used for indoor fiber cable reinforcement. It is…

  • Product features of FISO fiber optic connectors

    The optical fiber sensor is composed of a light source, an incident fiber, an exit fiber, an optical modulator, an optical detector, and a demodulator. The basic principle is that the light of the light source is sent to the modulation area through the incident fiber, and the light interacts with the measured parameters of the outside world in the modulation area so that the optical properties (such as intensity, wavelength, frequency, phase, and normality, etc. change and become The modulated signal light is sent to the photodetector and demodulator through the exit fiber to obtain the measured parameter. Fiber optic sensors can be divided into two categories according to the sensing principle: one is a light transmission type (non-functional)

  • Application analysis of FISO optical fiber connector

    According to the principle that light is modulated in optical fiber, optical fiber sensors can be divided into intensity modulation type, phase modulation type, polarization modulation type, frequency modulation type, and wavelength modulation type. So far, more than 70 physical quantities can be measured by optical fiber sensors. Compared with traditional sensors, fiber optic sensors have unique advantages: (1) High sensitivity. Since light is an electromagnetic wave with extremely short wavelengths, its optical length is obtained through the phase of light. Taking fiber interferometer as an example, due to the small diameter of the fiber used, its optical length will change when subjected to a small mechanical external force or temperature change, which will cause a large phase change. Assuming…
