QSFP28 Direct Attach Cables

100GBase Quad Small Form Factor Pluggable

QSFP28 DAC are hot-pluggable cables used for 100Gb data transmission. The term “QSFP” stands for Quad Small Form Factor Pluggable, a reference to the 4 independent 25Gb channels within the connectors. These cables utilize copper COAX wiring and are an ideal low-cost option for short reach applications. QSFP28 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.
