Molex has expanded its zSFP+ Interconnect System to support 56 Gbps PAM-4 channels in a stacked 2xN port configuration, allowing next-generation Ethernet and Fibre Channel applications to receive standout signal integrity. According to Molex, the product is the first of its kind on the market. It will allow OEMs requiring high-density interconnect applications to have the ability to utilize channels with individual lane data rates up to 56 Gbps PAM-4 in a stacked 2xN configuration. While providing those high speeds, the updated Molex product still maintains a low insertion loss, crosstalk, thermal and electromagnetic interference (EMI) containment that users are accustomed to from the previous zSFP+ Interconnect System.
The updated system has multiple features that allow for greater flexibility and lowered costs for users. The 56 Gbps PAM-4 channel products include EMI ganged cages—which are available in multiple port sizes from 2×1 through 2×12—allows for flexibility of PCB signal routing of LEDs.
Molex has also created a next-generation terminal and wafer on the stacked integrated connectors within the zSFP+ Interconnect System. The advanced terminal provides superior signal integrity for 56 Gbps PAM-4 applications. The system allows for users to merge standard cables and modules with the increased data-rate accepted.
