About DWDM Erbium-doped Fiber Amplifier
Jan 11 , 2023
In a longer fiber-optic line, DWDM Erbium-doped Fiber Amplifier are installed at specified distances for the purpose of ensuring the recovery of signals weakened by the fiber. Erbium-doped fiber amplifier EDFA can amplify any form of optical signal, and, at the same time, to recover a large number of independent WDM channel signals. However, Erbium-doped fiber amplifiers, which provide power ampli...

What is the difference between WDM and OTN?
Feb 17 , 2023
WDM and OTN are two different communication technologies, the differences are as follows: WDM (Wavelength Division Multiplexing): WDM is an optical transmission technology that uses optical signals of different wavelengths to multiplex multiple data streams on one optical fiber to increase the transmission capacity of the optical fiber. WDM technology combines optical signals of different waveleng...

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...

What are the advantages of multiplexing
Mar 28 , 2023
Multiplexing is a technique used in telecommunications and computer networks that allows the transmission of multiple signals over a single physical medium. It is the process of combining multiple signals into one for transmission over a shared medium. Advantages of multiplexing: 1. Increased efficiency: Bandwidth can be used more efficiently, and multiplexing allows multiple signals to be transmi...

WDM filter plays a very important role in DWDM system
Apr 11 , 2023
A WDM (Wavelength Division Multiplexing) filter is a common optical device that can be used to separate and combine optical signals of different wavelengths. In optical fiber communication, WDM filters are widely used in DWDM (Dense Wavelength Division Multiplexing) systems for multiplexing and demultiplexing. The working principle of WDM filters is based on the principle of optical interference. ...
