IEEE802.3ck Solution

The following chart is calibration test setup of Ethernet PAM4 technology, especially for Ethernet signals over Optical fiber networks, due to long-distance and high-speed data interconnection worldwide, that requires high efficiency, low latency and no signals loss. PAM4 is one of crucial technologies implementing in the industrials with decades to come, for example, PAM4 plays a key role in data centers and cloud computing environments to support the high-bandwidth requirements of virtualization, storage, and processing. It helps optimize the efficiency and speed of data transfers within and between data centers.
PAM4, on the other hand, uses four different signal levels to represent two bits of data at a time, effectively doubling the data rate for a given bandwidth.
