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...

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...

Optical fiber coupler structure and principle analysis
Jan 26 , 2022
Optical fiber coupler is a kind of optical fiber passive device used for transmitting and distributing optical signal. Optical fiber couplers generally have the following characteristics: First, the device is composed of optical fiber, which is an all-fiber device; second, the demultiplexing and combining of the optical field are mainly realized by mode coupling; third, the optical signal transmis...

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...
