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...

A Comprehensive Introduction to Tunable DWDM Transceivers
Jul 21 , 2022
Tunable DWDM transceivers allow users to adjust their wavelengths according to actual network needs. This results in a reduction in the number of spare transceivers used to avoid DWDM network failures and provides flexibility to accommodate growing networks. Tunable modules on the market mainly include 10G SFP+, XFP and 25G SFP28 tunable DWDM transceivers. So, is there any difference between tunab...
