  • 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…

  • About the function, structure and characteristics of optical fiber connectors

    Optical fiber connectors are divided into optical fiber fixed connectors, that is, fixed connections between the relay sections. The methods of fixing the joints include the fusion welding method, the V-groove method, the capillary method, and the sleeve method. Optical fiber connector, commonly known as a live joint, generally known as optical fiber connector, is between the optical fiber line and the equipment Removable connection. The function of optical fiber active connector and adapter (1) It can form a continuous optical path (2) Repeatable loading and unloading (3) Active connection with active or passive devices (4) Active connection with system and instrument It is widely used in long-distance trunk network, metropolitan area network, access network, optical fiber CATV network, optical…

  • 2020 optical cable customer analysis

    In addition to some research and development, the production of indoor optical cables is basically a processing industry, and the materials actually account for the vast majority of price costs. Therefore, the mainstream suppliers of indoor optical cable materials basically belong to the stronger side and play a very important role in the indoor optical cable market competition. In addition, the indoor optical cable is basically in the buyer's market, and the customer can have certain negotiation advantages in price, quality, service or other sales terms, which is strong market competitiveness. Even if the purchase volume of the customer is not large, or it cannot bring an important market or a certain reputation to the manufacturer, it still has a…

  • What to do when the optical cable is spliced

    What to do when the optical cable is spliced A. Pay attention to the cutting depth when the optical cable is stripped. The key to stripping the outer sheath of the optical cable is to master the cutting depth of the sheath cutting knife, otherwise, it is easy to break the fiber. In actual operation, the sheath cutter should be rotated while watching the incision. If you can see the white polyester tape, you should stop the knife and remove the cutter. This step is a proficient process and requires many exercises to master the depth of penetration. B. Fixing of optical cable and stripping of fiber bundle tube. After the optical cable is stripped, fix the optical cable in…

  • 2020 indoor optical cable market trends and market opportunities

    Although the communication cables at the user end are still mainly digital cables, with the rapid expansion of data on the Internet and the large increase in access networks and user premises, digital cables will be difficult to meet this development demand, and the indoor optical cable market will be steadily year by year. Expansion, the situation is very optimistic, this is the development trend of the market. In the early indoor optical cable market, single-core and dual-core optical cables were usually purchased by some jumper factories. The optical cable structure was few and the market was relatively single. For several reasons, first, the increasing demands of users have led to an increase in the variety of indoor optical cables.…

  • Four common categories of indoor optical cable

    A vertical lifting optical cable (Riser) After the optical cable enters the building, it is necessary to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinets on different floors, called "vertical wiring system". At this time, the wiring optical cable is mostly located in the vertical pipe (Riser) of the shaft between floors. For this reason, the optical cable needs to withstand a greater tensile force (maximum dead weight). Two single-core and double-core interconnection indoor optical cables (Interconnectcable) Indoor optical cable with tight-sleeve single-core, tight-sleeve 8-character double-core, tight-sleeve 2-core to 4-core round structure. Due to the use of tight-sleeve structure with very good flexibility and high-load aramid yarn around the tight-sleeve fiber, the…

  • Did you know that indoor optical cables are classified according to the environment in which the optical cables are used

    Indoor optical cables are classified according to the environment in which the optical cables are used, as opposed to outdoor optical cables. The classification of indoor optical cables. Due to the limitations of the building environment and laying conditions, the indoor optical cables have become more complicated in structural design, the materials used for optical fibers and optical cables are diversified, and the mechanical and optical properties of optical cables have different emphasis. a. divided according to the use environment and location It can be divided into three types: indoor backbone optical cable, indoor distribution optical cable and indoor relay optical cable. Indoor backbone optical cables mainly provide channels between inside and outside of buildings; indoor distribution optical cables and…

  • What is an underground cable

    Underground cable refers to the cable that is often buried in the ground compared to common overhead lines, so it is also called underground cable. Cables are made of one or more insulated conductors and protective layers that are insulated from each other, and are used to transfer power or information from one place to another. After entering the modern society, due to the shortage of urban land, heavy traffic pressure, and appearance construction, large cities generally use underground cable transmission. Compared with the overhead line, the cable has the advantages of small footprint, reliable power transmission, and strong anti-interference ability. The construction scheme, protective measures, census procedures, basic requirements of directly buried cables and underground cable fault locator are…

  • The difference between single-mode and multi-mode fiber jumper

    The concept of single-mode and multi-mode is to classify fibers according to the propagation mode-the concept of multi-mode fiber and single-mode fiber propagation mode. In the field of optical fiber data transmission, the term "mode" is used to describe the propagation mode of optical signals in the optical fiber glass core-that is, the mode is the propagation path of light. Therefore, in single-mode fiber, light travels along one path; in multimode fiber, light travels in multiple paths. 1 Appearance: The jacket of the single-mode fiber jumper is generally yellow, and the multimode is generally orange or the so-called aqua (that is, the color between blue and green); in terms of core diameter, the multimode In general, it is slightly thicker.…
