Specifications

1m (3ft) Arista Networks CAB-D-8S-400G-1M Compatible 400G QSFP-DD to 8x 50G SFP56 Twinax DAC Cable (1m, Passive, 0-70°C, 400G QSFP-DD to 8 x 50G SFP56)

            

Arista Networks CAB-D-8S-400G-1M compatible 400G QSFP-DD to 8x 50G SFP56 passive cable component product, based on 8x 50G structure, 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 factor of SFP +, which provides a more cost-effective solution for enterprises to upgrade 25G Ethernet connection.

                    

400G QSFP DD to 8x 50G SFP56 supports interconnection of two interface devices, with single channel transmission rate of 25Gbps (NRZ) or 50Gbps (PAM4).
