Add-On MCP7H60-W003R26-AO Mellanox Compatible TAA 400Gbps QSFP-DD to 2xQSFP56 Direct Attach Cable

Overview

The Add-On MCP7H60-W003R26-AO is a TAA-compliant direct attach copper (DAC) cable designed to split a single 400Gbps QSFP-DD port into two independent 200Gbps QSFP56 links. This cable is ideal for network engineers and data center operators who need to aggregate bandwidth from a high-density switch port to multiple downstream devices, such as servers or other network appliances, without requiring optical transceivers and their associated power consumption. Its passive copper construction ensures a cost-effective and low-latency solution for short-reach interconnects within racks or adjacent racks.

Compatibility

This cable is Mellanox compatible and designed to work with QSFP-DD ports on network switches and adapters. It specifically supports splitting a 400Gbps QSFP-DD connection into two 200Gbps QSFP56 connections. Verify your switch or adapter port type and speed requirements before deployment.

Installation Notes

Direct attach copper cables offer a plug-and-play experience. Ensure the QSFP-DD connector is fully seated in the host port and the two QSFP56 connectors are securely plugged into their respective downstream ports. For optimal performance and to prevent signal degradation, keep cable bends to a minimum and avoid sharp kinks. The passive nature of this cable means it draws no power from the host ports.
