What is a DWDM optical module?
Oct 22 , 2021
DWDM optical module belongs to a kind of WDM optical module. It uses DWDM technology to multiplex multiple optical signals into one optical fiber to transmit data using different wavelengths. This operation does not need to consume any power. These optical modules are designed for high-capacity and long-distance transmission, with a rate of up to 10Gbps and a working distance of up to 120km. Class...

Analysis of the advantages and disadvantages of passive DWDM Mux
Nov 05 , 2021
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 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 ...
