  With the continuous evolution of the Internet and digital communication, coupled with the growing demand for bandwidth, DWDM technology has become an indispensable element. By constructing DWDM networks, we can achieve the transmission of different wavelength signals within the same optical fiber, with the ability to cover ultra-long distances ranging from hundreds to thousands of kilometers. DWDM networks, characterized by their outstanding ultra-long distance transmission performance and the capability to transmit multiple wavelength signals within a single optical fiber, have become a crucial component in the realms of the Internet and communication. What is DWDM Technology? Dense Wavelength Division Multiplexing (DWDM) is an optical transmission technology that achieves high bandwidth and long-distance data transmission by simultaneously transmitting multiple different wavelengths of signals over a single optical fiber. The wavelength bands of DWDM are typically divided into ...

  We always hear about white light modules, gray light modules and colored light modules. What exactly are they and what are the differences? Let’s talk about it today. Before talking about gray light and colored light, let’s first look at what white light is. White light is defined as: mixed light of different colors, including all colors (wavelengths) in the spectrum, such as ultraviolet light, visible light, infrared light, etc., so it has the highest brightness and is called “white light”. Gray light and colored light are also discussed in this range, but the range is in the near-infrared region. So what are the differences between gray light and colored light? As we all know, SDH technology was the earliest used in optical transmission systems. In the optical path of SDH, one of our optical fibers only transmits one signal and one wavelength, and only one car runs in a large lane. The wavelength of this signal does not have strict requirements on the center wavelength. It only...

In our country, most communication power supplies use -48V power supply. As a communicator, do you know why? Before solving this question, let’s first understand where the -48V power supply comes from! █ How is -48V power generated? The power supply for communication equipment can be AC ​​power or DC power. To achieve uninterrupted power supply, in addition to UPS (Uninterruptible Power Supply, uninterruptible power supply), we must rely on the power stored in batteries. The monitoring module is responsible for the management of the entire system and transmits data to the remote monitoring terminal. The picture below takes the mains power as an example to introduce the working structure of the communication power supply system. As can be seen from the picture above ,  the -48V power supply is converted from alternating current or high-voltage direct current through a rectifier module  . █Why use -48V power supply? Seeing this, many people will ask: Why is the power supply volt...
