BlueOptics Lenovo 4Z57A11477 Compatible BlueLAN QSFP56 Breakout Direct Attach Cable (DAC) - Passive 200G to 2x100G Twinaxial Copper, QSFP56 to 2xQSFP56, for Rack and Adjacent Rack Connectivity

The BlueOptics Lenovo 4Z57A11477 compatible BlueLAN QSFP56 Breakout Direct Attach Cable (DAC) is a high-performance passive twinaxial copper cable designed for 200 Gigabit Ethernet and InfiniBand applications. It breaks out a single QSFP56 port into two 100 Gbps QSFP56 ports, enabling efficient connectivity between switches, servers, and storage within racks or across adjacent racks. This cable is a cost-effective and reliable solution for data center interconnects, offering low latency and zero power consumption.

Advantages

Passive design ensures no power consumption and minimal heat generation. Breakout configuration maximizes port utilization and reduces cable clutter. Twinaxial copper construction provides excellent signal integrity over short distances. Hot-pluggable QSFP56 connectors allow for easy installation and maintenance. Compatible with Lenovo 4Z57A11477 and other standard QSFP56 interfaces.
