QSFP+ to 4x SFP+ Passive Breakout DAC Cable

Volex’s QSFP+ to 4x SFP+ passive breakout Direct Attach Copper Cable is a cost-effective alternative to optical modules for short reach high-speed interconnects. The cable assembly enables breakout of 40GbE QSFP+ port to 4x 10GbE SFP+ ports, optimising data centre solutions for interconnecting 40G Ethernet switch port to 4x 10G server ports.

Volex’s QSFP+ breakout cable assembly combines twinaxial shielded cable with robust die cast housing and actuating pull latch. The overmould technique used in fabrication for these cables provides additional strain relief and minimises conductor pistoning. This cable assembly product is designed to meet the stringent data centre requirements with unparalleled performance and durability
