SFP56 Passive DAC Cable

Volex’s SFP56 passive Direct Attach Copper cable features 1 transmitting and 1 receiving channels supporting 50G Ethernet and 64G Fibre Channel applications. The Volex SFP56 cable assemblies meet or exceed IEEE 802.cd and 64GFC standards with substantial signal integrity margin providing high performance and bandwidth interconnect solutions for high-density applications.

As next-gen data centres deploy faster speed in a tighter space, they need high-performance cables that reduce power consumption, provide reliable operation and are low cost. Volex’s SFP56 cable assemblies are designed to meet the next-gen data centre needs. The Volex SFP56 cable pluggable module is compatible with SFP56 and SFP-DD ports for ease of data centre upgrade.
