Chelsio QSFP+ 1m Direct Attach Copper (DAC) kaapeli - 40GbE passiivinen QSFP+ - QSFP+ - musta

The Chelsio QTAPCABLE1M is a high-performance 1-meter QSFP+ direct attach copper (DAC) cable designed for 40 Gigabit Ethernet connectivity. This passive cable provides a cost-effective, low-power solution for short-range interconnects in data centers, high-performance computing (HPC), and enterprise networks. It is fully compliant with IEEE 802.3ba (40GBASE-CR4) and SFF-8436 standards, ensuring reliable operation with Chelsio and other MSA-compliant equipment.

Advantages

This DAC cable offers several benefits over optical transceivers: lower power consumption (<0.1W), reduced latency, and no need for cleaning or alignment. The passive design ensures zero power draw from the host device, making it ideal for high-density environments. The 30 AWG construction and PVC jacket provide durability and flexibility for easy cable management.

Suitable for

• Data center top-of-rack (ToR) to server connections
• High-performance computing clusters
• Enterprise network switches and routers
