How to use WDM technology to expand fiber capacity?
WDM technology expands the capacity of fibers by simultaneously transmitting multiple optical signals of different wavelengths in the same fiber, making one fiber act as multiple virtual links. The core principle of wdm systems is to use the difference in wavelength to distinguish channels: DWDM Technology Types For efficient capacity expansion, WDM technology is mainly divided […]
What’s the difference between CWDM and DWDM?
With the continuous enrichment of network services and high capacity demand, wavelength division multiplexing (WDM) technology has emerged. What is WDM? WDM is a communication technology that combines a series of optical signals with different wavelengths that carry information into one beam at the sending end and transmits them along a single fiber; at the […]
What are the types of optical multiplexers?
WDM (Wavelength Division Multiplexing) technology is the preferred solution for 5G fronthaul networks. According to different wavelengths, it can be divided into DWDM, CWDM, FWDM, MWDM and LWDM. Among them, CWDM and DWDM are the most common. First, let’s take a brief look at the main optical wavelengths. The CWDM wavelength range specified by ITU (ITU-T […]
Basic Knowledge Of wavelength Division Multiplexing WDM
What is WDM and how it works? WDM (wavelength division multiplexing) is a technique where two or more optical carrier signals of different wavelengths (carrying various information) are combined at the transmitting end through a combiner (multiplexer) and connected to the same optical fiber for transmission. At the receiving end, the optical signals of various […]
What is the difference between CWDM optical transceiver and ordinary optical transceiver?
With the development of the optical communication industry and the accelerated promotion of 5G, related peripheral industries are also growing rapidly, and the optical transceivers industry is no exception. In addition to our common optical transceivers, there are also WDM optical transceivers. Today, we will talk about the difference between ordinary optical transceivers and CWDM […]
Wavelength Division Multiplexer
WDM is Wavelength Division Multiplexer, WDM technology refers to the technology of combining two or more different wavelengths of optical signals at the transmitting end through a multiplexer (or Multiplexer) and coupling them into one fiber in the optical line for transmission. At the receiving end, the mixed signals are demultiplexed (or Demultiplexer) to separate […]
