Description

Passive copper breakout for flexible aggregation from a single QSFP-DD 400G port to eight SFP lanes, suitable for 50/25GbE depending on platform support. Extended 2 m reach gives extra routing flexibility while retaining ultra-low latency and zero power draw. Ideal for dense leaf/TOR deployments and server connectivity.

Features

- 2 m reach for flexible short-distance routing
- Zero power, minimal latency interconnect
- QSFP-DD 400G to 8x SFP breakout for dense server aggregation
- Standards-aligned CR copper interfaces for robust operation
- Hot-pluggable and tool-less deployment
- Cost-effective alternative to optical breakouts
- Excellent for TOR/leaf-spine topologies
- Rugged twinax construction

FAQs

Q: What is the maximum aggregate bandwidth?
A: Up to 400 Gbps across eight breakout lanes.

Q: Is this suitable for 25GbE endpoints?
A: Some platforms support 25GbE on SFP lanes; verify your switch/NIC documentation for lane speed support.

Q: Does it require optics or separate transceivers?
A: No. Being a DAC, it plugs directly into the ports.

Q: What is the primary deployment scenario?
A: Short-reach intra-rack or adjacent-rack breakout from a 400G QSFP-DD port to server SFP ports.

Q: Is any special licensing needed?
A: No license is required for using the cable; ensure the hardware ports support the intended speeds.
