What are the performance indicators that affect the WDM wavelength division multiplexer?
Sep 26 , 2021
What are the performance indicators that affect the WDM wavelength division multiplexer? 1. Working band The working band of WDM devices, such as 1550 wavelength, is divided into three bands: S band (short wavelength band 1460～1528nm), C band (conventional band 1530～1565nm), L band (long wavelength band 1565～1625nm). 2. Number of channels and channel spacing The number of channels refers to the nu...

What is Dense Wavelength Division Multiplexing
Mar 08 , 2022
The so-called dense is relative to the interval between two adjacent wavelengths. In the past, the wavelength interval of the wavelength division multiplexing system was several tens of nanometers. Now the wavelength interval is only 02 to 1.2 nm. The spectrum allocation is shown in Figure 2-1. DWDM technology is actually a specific form of wavelength division multiplexing. Generally, the waveleng...

Working principle and application of wavelength division multiplexing technology
Aug 04 , 2023
Working principle of WDM technology The working principle of WDM technology is based on the properties of the optical spectrum. In a WDM system, multiple light sources generate optical signals at different wavelengths and mix these signals together. These signals are then transmitted through an optical fiber. At the receiving end, a demultiplexer is used to separate the signals of different ...
