BLUELAN Compatible Mellanox MCP7H50-H002R26 Passive Breakout Direct Attach Cable (DAC) 200G QSFP-DD to 2x100G QSFP28 Twinaxial Copper 2m

The BLUELAN MCP7H50-H002R26-BL is a high-performance passive breakout Direct Attach Cable (DAC) designed for 200 Gigabit Ethernet connectivity. It provides a cost-effective and reliable solution for interconnecting data center equipment, converting a single QSFP-DD port into two 100GbE QSFP28 ports. This twinaxial copper cable is ideal for short-range links within racks or between adjacent racks, ensuring low latency and ultra-low power consumption.

Advantages

This cable offers seamless compatibility with Mellanox MCP7H50-H002R26-based systems, delivering full 200G aggregate bandwidth. The passive design requires no external power, reducing overall energy costs. Its breakout configuration maximizes port utilization and simplifies cable management in high-density environments. The robust construction ensures reliable signal integrity over the 2-meter length.
