Juniper QFX‑QSFP‑DAC‑1M 1‑Meter QSFP+ Direct Attach Copper Cable

The Juniper QFX‑QSFP‑DAC‑1M is a high‑performance QSFP+ Direct Attach Copper (DAC) cable designed for short‑reach, high‑speed connectivity between QSFP+ ports in data center and enterprise network environments. Engineered for use with Juniper QFX Series switches and other compatible QSFP+‑enabled devices, this 1‑meter passive DAC delivers reliable 40 Gbps connectivity (4×10 Gbps lanes) with low power consumption and minimal latency, making it an economical choice for short interconnects such as Top‑of‑Rack (ToR) switch‐to‐server or switch‑to‑aggregation links.

The QSFP+ DAC form factor enables plug‑and‑play deployment without the need for optical transceivers or fiber cabling, simplifying installation and lowering total cost of ownership (TCO). It supports the QSFP+ Multi‑Source Agreement (MSA) standards and is compatible with Juniper networking platforms that accept QFX‑branded DAC modules. Short DAC cables like the 1 m version are ideal for rack‑adjacent connections where high‑speed 40 GbE interfaces are required without distance extension.

Key Features:
• 1 Meter Passive QSFP+ DAC for 40 Gbps short‑reach links between QSFP+ ports.
• QSFP+ MSA compliant for broad compatibility with Juniper QFX and other QSFP+ platforms.
• Low‑latency, low‑power direct copper connectivity.
• Plug‑and‑play, no optical transceivers or optics required.
• Ideal for ToR, leaf‑spine, or aggregation links within the same rack or adjacent racks.
