BlueOptics Broadcom DAC-3M-BC Compatible Direct Attach Cable (DAC) - Passive 10 Gigabit Twinaxial Copper, SFP+ to SFP+, 3m

The BlueOptics Broadcom DAC-3M-BC compatible Direct Attach Cable (DAC) is a high-performance, passive 10 Gigabit Ethernet solution designed for reliable connectivity in data centers and enterprise networks. This 3-meter twinaxial copper cable features SFP+ connectors on both ends, enabling seamless connections between switches, servers, and storage devices within racks or across adjacent racks. As a passive DAC, it offers ultra-low power consumption and zero latency, making it an ideal choice for high-density environments where energy efficiency and signal integrity are critical.

Advantages

This cable provides a cost-effective and power-efficient alternative to active optical cables and transceivers. Its passive design eliminates the need for external power, reducing overall energy costs and heat generation. The twinaxial copper construction ensures excellent signal quality over short distances, with impedance matching at 100 Ohms for reliable 10GbE performance. Hot-swappable SFP+ connectors allow for easy installation and maintenance without network downtime.

Suitable for

• Connecting servers to top-of-rack switches in data centers
• Interconnecting adjacent racks in enterprise networks
• High-density 10 Gigabit Ethernet deployments requiring low power and low latency
• Broadcom DAC-3M-BC compatible hardware environments
