50G BASE SFP56 Transceiver Module

        The 50G optical modules are concentrated on the connection between the NIC and ToR in the super-large

data center. The 50G optical modules based on single-mode fiber transmission are mainly concentrated in the telecommunications field. In order to save the cost of 5G deployment, combined with the basic rate of 25Gbps, a

small number of 50G optical modules based on PAM4 modulation will be used in the convergence layer of the 5G transmission.  

          X-Krama's 50G SFP56 optical module uses PAM4 high-order modulation technology, which can transmit

twice the amount of information relative to NRZ signals under the condition of 25G physical bandwidth, realizing single-channel 50GE applications.
