Juniper EX-QSFP-40GE-DAC-50CM 40 GbE QSFP+ DAC Cable | Twinax Copper

Keep adjacent 40 GbE ports connected with a short, passive direct-attach copper cable designed for tight rack layouts and predictable performance. The 50 cm length is ideal when switches, servers, or appliances sit in the same rack or in immediately adjacent positions, reducing cable slack and simplifying airflow management. This QSFP+ DAC uses twinax copper construction to provide a direct electrical path without separate optics or transceivers. That means fewer components to source, fewer points of failure, and faster deployment in environments where port density matters. For teams standardizing on short-reach interconnects, it offers a practical way to preserve budget for higher-value optics where distance actually requires them. Use it where low-latency, short-distance connectivity is the priority: top-of-rack switching, leaf-spine adjacency, or storage and compute links inside a single cabinet. The result is a cleaner install and a more efficient 40 GbE fabric built for operational simplicity.
