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.
Laser line width, the full width at half maximum of the emission spectrum of the laser light source, that is, the half height of the peak (sometimes 1/e), which corresponds to the width between the two frequencies.
A device that converts the CO concentration variable in the air into a corresponding output signal.
Optical fiber temperature measurement technology is a new technology that has only been developed in recent years, and has gradually revealed some excellent characteristics. But just like other new technologies, optical fiber temperature measurement technology is not a panacea. It is not used to replace traditional methods, but to supplement and improve traditional temperature measurement methods. By giving full play to its strengths, new temperature measurement solutions and technical applications can be created.
Local Area Network (LAN for short) refers to a group of computers interconnected by multiple computers and other devices in a certain area. They are not far away from each other in physical locations to allow users to communicate with each other and share printers and storage. A system in which computing resources such as devices are interconnected together.
Let's take a look at which scenarios the DFB Butterfly Lasers is mainly used in.
