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...

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 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...

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 are the types of optical amplifiers
Nov 18 , 2021
Optical amplifiers can be divided into two categories: One type is that semiconductor optical amplifiers are made of semiconductor materials and can be regarded as semiconductor traveling wave optical amplifiers without feedback. The other is a fiber amplifier, which includes two types, one is a nonlinear fiber amplifier, which uses a strong light source to excite the fiber, so that the fiber prod...
