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...

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...

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 ...
