Juniper QSFP+ 40GE Active DAC 7M JNP-QSFP-DAC-7MA | Active Cable

When a 40 GbE link needs more reach than a passive DAC can provide, an active direct attach cable is the right tool. The Juniper JNP-QSFP-DAC-7MA is a 7 m QSFP+ active DAC designed for short-to-medium interconnects where you want to preserve copper simplicity while covering a longer span between devices. This cable is well suited to data center layouts that place switches, servers, and appliances across adjacent racks or within a row. The active design supports longer copper runs than passive DAC options, helping teams avoid the added cost and operational complexity of optical modules when the distance still fits within a copper-based architecture. For procurement teams, the value is clear: fewer transceivers to manage, less inventory fragmentation, and a purpose-built cable for 40 GbE links that do not justify optics. For operations teams, the benefit is equally practical: a single integrated assembly that keeps deployment straightforward and cable management under control. In dense environments where every port and every dollar matters, this cable fills the gap between short passive DACs and more expensive optical alternatives.
