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...

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 ...
