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 […]
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 […]
