BlueOptics Q28-4S28-DAC-2M-CN-BL kompatibilný s Cumulus QSFP28 na 4x SFP28 Direct Attach Breakout kábel, 2m, pasívny, AWG26

The BlueOptics Q28-4S28-DAC-2M-CN-BL is a high-performance, passive Direct Attach Breakout Cable designed for reliable 100G connectivity in data center and high-performance computing environments. This cable is fully compatible with Cumulus switches and NICs, providing a cost-effective solution for breaking out a 100GBASE-CR4 QSFP28 port into four independent 25GBASE-CR SFP28 links.

Advantages

This breakout cable offers significant advantages over traditional transceivers and fiber cabling. It provides a low-power, low-latency, and cost-efficient interconnect for short-range applications. The passive design ensures zero power consumption, while the breakout configuration maximizes port utilization and simplifies cable management. With a length of 2 meters and AWG26 gauge, it is ideal for top-of-rack to server connections.

Suitable for

• Data center interconnects
