Planet 40G QSFP+ na 4x 10G SFP+ 5m Direct Attach medený kábel - kábel - 5 m

For high-density 40G Ethernet and InfiniBand fabrics, this passive direct attach copper breakout cable splits a single QSFP+ port into four independent 10G SFP+ links—without the power draw, latency, or cost of optical transceivers. At 5 metres, it reaches across adjacent racks in data centres and HPC clusters, delivering a dependable 40 Gbps aggregate path that plug-and-play simplicity makes effortless to deploy.

Highlights

• 1× QSFP+ to 4× SFP+ breakout configuration for 40G-to-10G fan-out
• Passive copper design: under 0.5 W total power consumption, no external power needed
• Aggregate 40 Gbps bandwidth (4× 10 Gbps lanes) with 100 Ohm differential impedance
• Compliant with SFF-8436, SFF-8431, and IEEE 802.3ba 40GBASE-CR4
• Hot-swappable connectors for zero-downtime maintenance
• 5 m length ideal for top-of-rack to adjacent rack or row-end connectivity

In daily use

Install it in seconds: plug the QSFP+ end into a 40G switch or NIC, then connect the four SFP+ ends to 10G servers, storage, or uplinks. Because it is passive, there is no firmware to manage and no active electronics to fail—just a robust copper link that maintains signal integrity across the full 5 m span. The cable operates reliably from 0°C to 70°C, making it suitable for both air-conditioned and warm-aisle environments.
