SFP-DD Passive DAC Cable

Volex’s SFP-DD passive Direct Attach Copper cable features 2 transmitting and 2 receiving PAM4 channels supporting 100G Ethernet (2x 50Gb/s) and 2x 64G Fibre Channel applications. The Volex SFP-DD cable assembly meets IEEE 802.cd and 64GFC standards with substantial signal integrity margin providing high performance and bandwidth interconnect solutions for next generation data centre needs.

As data centres grow and deploy faster speed in a tighter space, they need high performance cables that have less power consumption, reliable operation, are low cost and can be supplied fast in large quantities. By partnering with Volex on SFP-DD and other high-speed cables, today’s data centres benefit from Volex’s global manufacturing footprint and technical expertise to help future-proof their data centre and fulfil infrastructure development goals.
