QSFP56 to 4x SFP56 Passive Breakout DAC Cable

Volex’s QSFP56 passive breakout Direct Attach Copper cables feature 4 transmitting and 4 receiving channels at 50Gbps with PAM-4 modulation per channel. 200Gbps (QSFP56) to 4x 50Gbps (4x SFP56) breakout configurations are supported. The cable assemblies meet 50Gbps Ethernet (IEEE 802.3cd) standard 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 QSFP56 breakout cable assemblies are designed to meet the next-gen data centre needs. The Volex QSFP56  breakout cable pluggable modules are compatible with QSFP-DD and QSFP56 ports and, for the breakout ends, SFP-DD and SFP56 ports for ease of data centre upgrade.
