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 ...
