An electro-optic modulator (EOM) is a device that controls the power, phase or polarization of an optical signal through an electrical signal. Its core principle is based on the linear electro-optic effect (Pockels effect). This effect manifests itself in that the applied electric field is proportional to the refractive index change of the nonlinear crystal, thereby achieving effective control of the optical signal.

In data centers, optical modules exist everywhere, but few people mention them. In fact, optical modules are already the most widely used products in data centers. Today's data centers are basically optical fiber interconnection, and the situation of cable interconnection has become less and less. Therefore, without optical modules, data centers cannot operate at all. The optical module converts electrical signals into optical signals at the sending end through photoelectric conversion, and then transmits through optical fibers, and then converts the optical signals into electrical signals at the receiving end. That is to say, any optical module has two parts: transmitting and receiving. The function is to do photoelectric conversion and electro-optical conversion, so that the optical modules are inseparable from the equipment at both ends of the network. There are thousands of devices in a medium-sized data center.

Recently, Zhang Weijun, a researcher at Anhui Institute of Optics and Fine Mechanics, Hefei Institute of Physical Science, Chinese Academy of Sciences, has made progress in atmospheric nitrogen dioxide (NO2) detection technology. A new method for rapid and sensitive detection of NO2" was published in the American Chemical Society "Analytical Chemistry".

Optical fiber splice, which connects two optical fibers permanently or detachably, and has a splice part for protecting the components. The optical fiber splice is the end device of the optical fiber. The optical fiber connector is a physical interface used to connect an optical fiber cable. FC is the abbreviation of Ferrule Connector. The external reinforcement method is a metal sleeve and the fastening method is a turnbuckle. The ST connector is usually used for 10Base-F, and the SC connector is usually used for 100Base-FX.
