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...

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...

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 ...

The grating humidity sensor is made up of grating and humidity material as the main part of the humidity sensor. Monitor installation for easy surface installation.

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.

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, ...

Laser welding technology is a technique of fusion welding, which uses a laser beam as an energy source to impact the weldment joint to achieve the purpose of welding.

GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network servic...
