Passive wavelength division optical transmission solution--CWDM/DWDM
Dec 17 , 2021
In the construction of optical transmission networks, long-distance transmission needs to consume a lot of optical fiber resources. WDM passive components can multiplex multiple optical signals into one optical fiber, expand transmission capacity and save optical fiber resources. Among them, CWDM and DWDM devices are two of the more commonly used devices. Equipped with corresponding color light mo...

Advantages and disadvantages of Dense Wavelength Division Multiplexing (DWDM)
Jan 07 , 2022
Information network technology developers continue to strive to improve the throughput and quality of network data lines, while reducing the cost per bit (CPB) of the network. One of these technologies is dense wavelength division multiplexing (DWDM). DWDM is a method of creating multiple virtual fiber lines, which effectively increases the capacity of physical fiber lines. Wavelength division mul...

What are the ports on the WDM multiplexer/multiplexer?
Jan 11 , 2022
Wavelength Division Multiplexing (WDM) is a commonly used technology in optical communications. It combines multiple wavelengths to transmit signals on a single fiber. To implement this process, CWDM multiplexers/demultiplexers and DWDM multiplexers/demultiplexers are essential parts. As we all know, there are several different ports on WDM multiplexers and multiplexers. This article will give a c...

How to Use a Single Fiber CWDM Mux/Demux | Fiberwdm.com
Feb 11 , 2022
The biggest difference in the appearance of dual-fiber and single-fiber CWDM Mux/Demux devices is that the single-fiber version has a simplex line port. However, some of them are also made with duplex ports where only one port of the duplex is available and the other port is marked N/A. The main reason why this Mux/Demux enables bidirectional transmission is that it utilizes CWDM wavelengths diffe...
