Why choose it

Passive copper DACs are the most cost-effective solution for short 200G links. They consume less power than active optical cables and introduce no additional latency. This cable is fully compatible with Mellanox MCP1650-H02AE26, making it a drop-in replacement for original equipment in existing deployments.

Ideal use cases

• Top-of-rack (ToR) switch to server connections in data centers
• High-performance computing (HPC) cluster interconnects
• Enterprise network aggregation links
• Storage area networks (SAN) requiring high bandwidth

Good to know

The 30 AWG wire gauge balances flexibility and signal integrity for a 3-meter reach. With an operating range of 0°C to 70°C, it suits most controlled data center environments. The cable is hot-pluggable, allowing for easy installation and maintenance without powering down the connected devices.
