BlueOptics Dell GF37541 BlueLAN Passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ Direct Attach Breakout Cable, 3 Meter

The BlueOptics Dell GF37541 BlueLAN passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ Direct Attach Breakout Cable is a high-performance, cost-effective solution for data center and enterprise networking. This 3-meter passive twinax copper breakout cable enables seamless connectivity from a 40 Gbps QSFP port to four 10 Gbps SFP+ ports, ideal for high-density server-to-switch and switch-to-switch interconnects.

Advantages

This breakout cable offers significant advantages over traditional fiber optic solutions, including lower power consumption, reduced latency, and simplified cable management. The passive design ensures zero power draw, while the 30 AWG twinax construction provides reliable signal integrity over the 3-meter length. MSA compliant and compatible with Dell GF37541 equipment, it guarantees interoperability and performance.
