NVIDIA Mellanox MCP1650-H002E26 200Gb/s QSFP56 DAC Cable

Brand:

NVIDIA Mellanox

NVIDIA Mellanox MCP1650-H002E26 is a 2-meter passive copper Direct Attach Cable (DAC) designed for InfiniBand HDR up to 200Gb/s and 200GbE applications. It uses QSFP56-to-QSFP56 connectivity and 26-AWG copper construction, making it a practical short-reach interconnect for high-bandwidth servers, switches, HPC clusters, GPU infrastructure, and data-center fabrics. NVIDIA lists this specific SKU as an HVM cable.

OVERVIEW

The MCP1650-H002E26 is a 2m passive copper cable for 200Gb/s HDR InfiniBand and 200GbE links. Compatibility: QSFP56-to-QSFP56 equipment supporting the relevant 200Gb/s interface; verify device qualification. Model comparison: H002E26 is 2m/26-AWG, while H00AE30 is 0.5m/30-AWG and H001E30 is 1m/30-AWG.

USE CASES

HPC cluster networking – Provides 200Gb/s-class connectivity between compatible compute and fabric equipment.
AI and GPU infrastructure – Supports high-bandwidth links for distributed compute environments.
InfiniBand HDR fabrics – Provides a direct copper interconnect for supported HDR networking equipment.
200GbE data-center networks – NVIDIA validates the MCP1650-H002E26 for 200GbE applications as well as HDR InfiniBand.
Server-to-switch connectivity – The 2m length accommodates installations where 0.5m or 1m cables are insufficient.
High-performance storage networks – Suitable for compatible 200Gb/s storage and compute fabrics.
Dense rack deployments – Direct-attach copper minimizes unnecessary optical components for appropriate short-reach connections.
Data-center infrastructure upgrades – Provides an OEM-specific cable SKU for replacing or expanding compatible 200Gb/s links.
System-integrator projects – Simplifies BOM selection where QSFP56-to-QSFP56 2m connectivity is required.
Rack-scale networking – Useful for connecting adjacent or nearby servers and switches within structured rack layouts.

KEY FEATURES

Up to 200Gb/s bandwidth – Provides high-throughput connectivity for HDR InfiniBand and 200GbE environments.
Passive copper design – Offers a direct electrical interconnect for suitable short-reach deployments.
QSFP56-to-QSFP56 connectors – Enables straightforward connection between compatible QSFP56 ports.
2-meter cable length – Provides additional routing reach compared with shorter MCP1650 variants.
26-AWG construction – Supports the specified mechanical profile for the 2m variant.
9.4 ± 0.4mm cable diameter – Gives infrastructure teams a defined physical dimension for rack planning.
47mm single-bend radius – Establishes a minimum routing radius for bends away from the connector.
94mm assembly/repeated bend radius – Helps protect the cable during installation and repeated handling.
LSZH construction – Supports data-center deployments requiring low-smoke, zero-halogen cable characteristics.
Black pull-tab design – Facilitates physical identification and handling during rack installation.
NVIDIA-defined MCP1650 family – Helps procurement teams distinguish the cable from similar-looking third-party QSFP56 DACs.
HDR and 200GbE applicability – Broadens deployment potential across supported InfiniBand and Ethernet environments.
