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...

What is WDM and how does it work?
Dec 24 , 2021
Main reasons for choosing DWDM multiplexer/multiplexer With the advent of the Internet, there is a huge influx of data. Although this is good for businesses because data is helpful in many ways, dealing with big data is a challenge. Efficient and powerful data transmission speed seems inevitable. In order to solve the paradox of increasing bandwidth with less expenditure, DWDM Mux/Demux is the per...

What is dcm dispersion compensation module？
Dec 29 , 2021
In the field of optical fiber communication, the dispersion compensation module (DCM) (also known as the dispersion compensation unit, DCU) is used to compensate for the dispersion, for example, to compensate for the dispersion in a long transmission fiber. Usually, this module provides a certain amount of dispersion, but there are also modules with tunable dispersion. Inserting the module into th...

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...

Function of CWDM filter
Jan 18 , 2022
CWDM filters are designed to multiplex and demultiplex wavelength signals in metro, access and enterprise networks, as well as cable television applications. Additionally, they are often used to provide the wireless backbone for the latest 4G wireless networks (LTE). They are a low-cost approach for systems using uncooled laser sources and an alternative to more expensive DWDM components based on ...

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...
