QSFP+ Direct Attach Cables

40GBase Quad Small Form Factor Pluggable

QSFP+ DAC are hot-pluggable cables used for 40Gb data transmission. The term “QSFP” stands for Quad Small Form Factor Pluggable, a reference to the 4 independent 10Gb channels within the connectors. These cables utilize copper COAX wiring and are an ideal low-cost option for short reach applications. QSFP+ DAC are ideal for high-speed transmission in data centers, cloud computing, and hyper-scale transmission and are compliant with RoHS, IEEE, and MSA standards.
