Juniper QSFP28 100G DAC 3M Cable | Direct Attach, 100 GbE

Keep high-speed links tight, predictable, and cost-controlled with the Juniper QSFP28 100G DAC 3M. This direct-attach copper cable is designed for short-reach 100 GbE connections between compatible QSFP28 ports, making it a strong fit for adjacent rack and same-row deployments. Compared with optical alternatives, a DAC removes the need for separate transceivers on both ends, reducing bill of materials, power draw, and points of failure. That matters in dense switching environments where port count, thermal load, and procurement efficiency all affect total cost of ownership. At 3 m, this cable is sized for practical data center layouts without excess slack. It supports clean cable management in top-of-rack, leaf-spine, and aggregation layers where short, direct runs are preferred. For teams standardizing on Juniper infrastructure, it offers a straightforward way to extend 100 GbE connectivity with the right balance of performance and simplicity.
