NVIDIA MCP7Y00-N003

Overview

The NVIDIA MCP7Y00-N003 is a passive copper splitter cable designed to connect a single OSFP port to two separate OSFP devices, effectively splitting one 800 Gb/s interface into two independent 400 Gb/s lanes. This cable is ideal for high-performance environments such as HPC clusters, AI training nodes, and large storage fabrics where maintaining high bandwidth and low latency is critical. Its three-meter direct attach design ensures minimal latency and eliminates the need for additional power or active components, making it a practical choice for dense data center racks.

Key features

• Splits one OSFP port into two OSFP interfaces, doubling connectivity options without extra switch ports
• Passive copper construction that requires no external power, reducing heat generation and simplifying cooling
• Supports InfiniBand NDR protocol, enabling compatibility with advanced networking standards for demanding workloads
• Three-meter cable length optimized for short-distance connections with consistent, low-latency performance
• Direct attach design that allows quick installation without the need for specialized transceivers or maintenance tools

Key specs

• Total bandwidth: 800 Gb/s aggregate throughput
• Channel bandwidth: Two independent 400 Gb/s lanes
• Cable type: Passive copper direct attach
• Cable length: 3 meters
• Supported protocol: InfiniBand NDR

Connectivity and compatibility

This splitter cable is tailored for data centers and environments using OSFP ports, commonly found in GPU clusters, scientific computing setups, and storage networks. It enables efficient use of switch ports by splitting a single high-speed interface into two, which helps maintain port density and reduces cable clutter at the top of the rack. The passive copper design ensures compatibility with existing OSFP infrastructure without requiring additional power or active components.

Ideal uses and environments

The MCP7Y00-N003 is well suited to data centers that demand high bandwidth over short distances, such as those running real-time analytics, scientific simulations, or AI workloads. Its passive design and low latency make it a strong choice for facilities aiming to optimize power consumption and cooling while maximizing network throughput. This cable fits naturally in setups where reliability and straightforward installation are priorities, especially in dense rack environments where space and port availability are limited.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Shipping costs are calculated at checkout based on destination, total weight, and selected speed. Free shipping applies to carts over $100 (excluding heavyweight items). All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.

Deliveries are handled by major carriers such as USPS, UPS, and FedEx. Estimated delivery times are displayed at checkout and may vary depending on service level and location. Please note that these are estimates and can be affected by weather, holidays, or carrier volume. Once your order ships, you’ll receive a tracking number for real-time updates from pickup to final delivery.

Providing an accurate shipping address helps prevent delays, and changes may be limited once the order has been dispatched. P.O. boxes are supported only when permitted by the selected carrier. Packaging and handoff are optimized to protect items during transit, though oversized or high-weight products may require special handling. All shipping methods and any related constraints are clearly shown during checkout.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
