Explanation of relevant knowledge points of WDM network
Dec 27 , 2022
A WDM network is a network that deploys optical WDM fiber links, where each link carries multiple wavelength channels. WDM, an acronym for Wavelength Division Multiplexing, is a technology that multiplexes multiple signals on a single optical fiber by using optical carriers of different wavelengths using lasers or LEDs. There is a multiplexer and a demultiplexer at each end of the WDM. A multiplex...

What is the difference between AOC optical cable and DAC cable
Feb 20 , 2023
What is DAC? DAC is a high-speed direct connection cable, also known as direct copper cable. This type of cable port cannot be replaced, and the module head cannot be separated from the copper cable. Copper cable is the most common direct cable connecting servers and storage area networks in data centers. Direct copper cable is divided into passive copper cable and active copper cable. Passive cop...

What is WDM and how it works?
Mar 09 , 2023
WDM stands for Wavelength Division Multiplexing. It is a technology used in fiber optic communication networks to increase the bandwidth capacity of a single optical fiber by transmitting multiple signals simultaneously at different wavelengths. In WDM, different data signals are assigned to different wavelengths of light, which are then transmitted over the same fiber. Each wavelength is modulate...
