Cost-effective advantage of 100G DWDM QSFP28 transmission solution | Fiberwdm.com
Feb 18 , 2022
In recent years, the single-wave 10G transmission mode has been the protagonist of the stage. However, with the popularization of 5G networks, the rise of the Internet of Things, and the application of big data, the data transmission capacity has exponentially increased, and the single-wave 10G transmission The speed will no longer be able to meet the needs of big data; the new corner of the forme...

Why Choose a 40-Channel DWDM Multiplexer/Multiplexer
Mar 04 , 2022
DWDM (Dense Wavelength Division Multiplexing) is an ideal optical multiplexing technology for long-distance data transmission, which can put multiple channel information using a single wavelength on the same fiber and greatly improve the transmission capacity of optical networks. At present, DWDM technology is widely used in telecommunication networks and has become the choice of many telecommunic...

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...

What is a CWDM/DWDM multiplexer/demultiplexer?
May 20 , 2022
As we all know, WDM (Wavelength Division Multiplexing) is a technology that uses multiple lasers to send multiple lasers of different wavelengths on a single fiber at the same time. It can realize two-way communication on one fiber and increase network capacity. In a WDM system, a multiplexer is generally used at the transmitting end to multiplex several optical signals into a bundle of optical ca...

Introduction of 100G DWDM QSFP28 CS Connector PAM4 Transceiver
Jun 09 , 2022
What is PAM4? PAM4 is a technology that uses four different signal levels for signal transmission, and each symbol period represents 2 bits of logical information (0, 1, 2, 3). By transmitting two bits in one symbol slot, PAM4 cuts the signal bandwidth in half. With half the bandwidth, PAM4 can achieve 50Gb/s data transfer in a 25Gb/s electrical tolerance environment. Additionally, PAM4 minimizes ...

Some related questions about WDM Mux Demux - FiberWDM
Jul 15 , 2022
What is the role of a multiplexer in WDM? WDM systems use a multiplexer at the transmitter to connect multiple signals together and a demultiplexer at the receiver to separate them. With the right type of fiber, it's possible to have a device that does both, and can function as an optical add/drop multiplexer. What is a fiber optic multiplexer? A multiplexer (or multiplexer) is a device that selec...
