QSFP28 to 2x QSFP28 Passive Breakout DAC Cable
Volex’s QSFP28 to 2x QSFP28 passive breakout Direct Attach Copper cables feature 4 transmitting and 4 receiving channels at 25Gbps per channel speed and support 100Gbps (QSFP28) to 2x 50Gbps (2x QSFP28) breakout configurations. The cable assemblies meet 25GbE Ethernet (IEEE 802.3by) 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 QSFP28 to 2x QSFP28 breakout cable assemblies are designed to meet the next-gen data centre needs. The Volex QSFP28 100G/EDR breakout cable pluggable modules are compatible with QSFP-DD, QSFP56 and QSFP28 ports for ease of data centre upgrade.
