NVIDIA Mellanox MCP7Y50-N003 800Gb/s NDR 4x200G OSFP Cable

Brand:

NVIDIA Mellanox

The NVIDIA Mellanox MCP7Y50-N003 is a 3-meter passive copper splitter cable designed for NDR InfiniBand connectivity. It connects a twin-port 800Gb/s OSFP interface to four 200Gb/s OSFP interfaces, providing a practical breakout topology for high-density AI, HPC and data-center fabrics. NVIDIA identifies the current OPN as 980-9I46T-00N003. The cable is a 26-AWG assembly and is part of the MCP7Y50-Nxxx passive copper splitter family.

OVERVIEW

The MCP7Y50-N003 is a 3m passive copper splitter cable for NDR InfiniBand, breaking an 800Gb/s twin-port OSFP connection into four 200Gb/s OSFP connections. Compatibility: supported NDR platforms using the specified OSFP interfaces. Model comparison: unlike shorter Nxxx variants, N003 provides 3m reach; it uses a fin-to-flat connector configuration.

USE CASES

AI GPU cluster fabrics — Breaks out an 800Gb/s NDR connection into four 200Gb/s links, supporting high-density accelerator networking architectures.
HPC interconnects — NDR InfiniBand support makes the cable suitable for compute environments requiring high-bandwidth, low-latency fabric connectivity.
800G-to-200G breakout — Provides a purpose-built physical connection for architectures transitioning from an 800Gb/s twin-port interface to four 200Gb/s endpoints.
High-density data-center racks — The 3m length provides additional routing distance while retaining a direct passive-copper connection.
AI server-to-switch connectivity — Useful where compatible NDR OSFP ports must be distributed across multiple 200Gb/s endpoints.
InfiniBand fabric expansion — Supports structured breakout cabling when expanding NDR network topologies.
Cluster-scale networking — Four 200Gb/s outputs can simplify port allocation in dense multi-node compute environments.
Rack-level cable management — The 3m assembly provides a defined cable length for installations requiring more reach than 1m or 2m variants.

KEY FEATURES

800Gb/s twin-port NDR input — Provides an 800Gb/s-class aggregation point for compatible NDR InfiniBand infrastructure, supporting high-throughput AI and HPC fabric designs.
4 × 200Gb/s breakout — Converts the twin-port 800Gb/s topology into four 200Gb/s connections, enabling greater port utilization in compatible NDR architectures.
OSFP-to-4×OSFP configuration — Uses OSFP connectors throughout the assembly, simplifying physical deployment where compatible OSFP ports are available.
Passive copper construction — Avoids active optical electronics within the cable, providing a direct copper interconnect option for supported short-reach data-center deployments.
3-meter length — Provides useful rack-level routing flexibility without moving to an unnecessarily long cable assembly.
26 AWG construction — NVIDIA's LinkX portfolio identifies the MCP7Y50-N003 as a 26-AWG cable, providing a specific physical cable specification for infrastructure planning.
Fin-to-flat configuration — NVIDIA identifies this N003 version as fin to flat, an important physical consideration when matching the cable to supported port and cooling configurations.
NVIDIA validated NDR cable — NVIDIA documentation lists MCP7Y50-N003 with current OPN 980-9I46T-00N003, helping procurement teams identify the exact assembly.

Why Choose This Product?

Purpose-built 800G breakout — Designed specifically for an NDR topology requiring four 200Gb/s endpoints from an 800Gb/s twin-port connection.
High-density port utilization — Four 200Gb/s branches can make better use of available switch or adapter connectivity in dense AI and HPC environments.
Passive architecture — The copper design provides a straightforward interconnect without active optical components inside the cable.
3m deployment flexibility — A longer cable option than 1m or 2m variants can simplify rack-level routing where short assemblies cannot reach cleanly.
NVIDIA ecosystem alignment — The exact SKU and current OPN are documented by NVIDIA, reducing procurement ambiguity when specifying compatible NDR infrastructure.
Designed for NDR InfiniBand — Appropriate for high-performance computing and AI fabrics where high-bandwidth accelerator-to-network communication is required.
Defined physical configuration — The 26-AWG specification and fin-to-flat construction help data-center teams plan cable routing and port clearance before deployment.
Part of a scalable cable family — Related MCP7Y50 variants offer different lengths, allowing organizations to standardize the cable family while selecting the appropriate physical reach.
