    LAN and plastic fiber media
    Local Area Network (LAN) refers to a group of computers interconnected by multiple computers and other devices in a certain area. They are physically apart from each other to allow users to communicate with each other and share such as printers and storage. A system in which computing resources such as devices are interconnected.
  • Optical fiber sensor network structure
    Optical fiber sensor network structure
    Fiber optic sensor networks have three basic components, one of which is called a single point sensor. One fiber only serves as a transmission here, and the other is a multi-point sensor, where a fiber bundles many sensors so that many sensors can share the light source for network monitoring. Then there is the smart fiber sensor. The multi-point fiber optic sensor is a grating...
  • The role of the optical module in the data center
    The role of the optical module in the data center
    In the data center, optical modules exist everywhere, but few mention them. In fact, optical modules are already the most widely used products in the data center. Today‘s data centers are basically fiber-optic interconnections, and the number of cable interconnections has become less and less, so there is no optical module, and there is no way for the data center to operate. T...
  • Advantages of fiber lasers
    Advantages of fiber lasers
    A fiber laser refers to a laser using a rare earth-doped glass fiber as a gain medium. The fiber laser can be developed on the basis of a fiber amplifier: under the action of pump light, a high power density is easily formed in the fiber, resulting in a laser of the laser working substance. The energy level "particle number inversion" can form a laser oscillation output when a ...

    Selection principle of sensor
    To carry out a specific measurement, the first consideration is what kind of sensor is used. Even if the same physical quantity is measured, there are several kinds of sensors available.

    Application of optical fiber sensing technology based on Internet of Things
    With the rapid development of optical fiber and optical fiber communication technologies, optical fiber sensing technology emerged. Since its birth, fiber optic sensors have been rapidly developed due to their small size, light weight, high sensitivity, fast response, strong anti-electromagnetic interference capability and ease of use, and are widely used in chemical medicine, ...
