BlueOptics Lenovo B68L Compatible Breakout Direct Attach Cable (DAC) Passive 200 Gigabit to 2x100 Gigabit Twinaxial Copper QSFP56 to 2xQSFP56

The BlueOptics Lenovo B68L compatible Breakout Direct Attach Cable (DAC) is a high-performance passive twinaxial copper cable designed for 200 Gigabit Ethernet breakout to 2x100 Gigabit Ethernet. It features QSFP56 connectors on both ends, enabling seamless connectivity between switches, servers, and storage devices in data center environments. This cable is ideal for rack-to-rack and top-of-rack (ToR) applications, providing reliable, low-latency data transmission with zero power consumption.

Advantages

This breakout DAC cable offers a cost-effective and energy-efficient solution for high-speed data center interconnects. Its passive design eliminates the need for external power, reducing overall power consumption and heat generation. The twinaxial copper construction ensures excellent signal integrity over short distances, making it perfect for adjacent rack connections. With hot-pluggable QSFP56 connectors, installation and maintenance are quick and easy, minimizing network downtime.

Suitable for

• Data center interconnect (DCI) applications
• Rack-to-rack and top-of-rack (ToR) connectivity
