Product Description

400g QSFP DD passive cable component product, based on 8x50g structure (pam4 signal), can well meet the requirements of the next generation 400g switch, server, router and other products.

The 400g QSFP DD cable assembly adopts optimized design to reduce crosstalk and insertion loss, has excellent signal integrity, and fully conforms to the next generation 400g Ethernet and Infiniband EDR standards.

SFP56 is based on the same shape of SFP +, supports 25g NRZ (or 50g pam4) Ethernet standard, can provide 25gb / s error free transmission, and can be applied to high-density 25g Ethernet switches and network interfaces to promote server connection in data center. It adopts the current popular form of SFP + packaging, which provides a more cost-effective solution for enterprises to upgrade 25g Ethernet connection.

400g QSFP DD to 8x50g SFP56 supports interconnection of two interface devices, with single channel transmission rate of 25gbps (NRZ) or 50Gbps (pam4).
