In recent years, with the rapid development of the Internet, cloud computing and big data, the increasingly high demand for bandwidth has promoted the construction of IT infrastructure data centers. The current speed standard of 10G Ethernet cannot meet the rapid growth of network traffic demands of large and medium-sized enterprises. From the perspective of resource investment and cost, 25G is th...

In this blog, ETU-LINK will talk about the 50G SFP56 SR optical module using PAM4 modulation technology. Since the PAM4 signal has four level values, the PAM4 signal can be used in the same physical bandwidth of the channel. Downlink transmission is twice the amount of information compared to NRZ signals, enabling single-channel 50G applications. Therefore, PAM4 signal modulation has become t...
