NVIDIA MFA7U10-H010

Overview

The NVIDIA MFA7U10-H010 is a 400 Gbit/s active optical splitter cable designed to convert a single OSFP port into two independent 200 Gbit/s QSFP56 links. This integrated cable assembly eliminates the need for separate transceivers or patch cords, simplifying high-speed network connections. With a 10 meter fiber length, it supports data center layouts that require connections across adjacent racks or rows, delivering low latency and reliable signal integrity through active optical cable (AOC) technology.

Engineered for InfiniBand HDR environments, this splitter cable is ideal for high performance computing clusters, AI training systems, and storage fabrics that demand consistent bandwidth and deterministic performance. It enables network administrators to optimize port usage by breaking out a 400 Gbit/s switch port into two 200 Gbit/s links, facilitating flexible network topologies and efficient bandwidth allocation.

Key features

• Splits a single 400 Gbit/s OSFP port into two separate 200 Gbit/s QSFP56 connections, maximizing switch port utilization
• 10 meter active optical fiber length supports flexible cabinet-to-cabinet and row-to-row data center cabling
• Active optical cable design reduces weight and electromagnetic interference compared to copper alternatives
• Plug-and-play operation with no need for fiber tip cleaning or polishing, simplifying installation and maintenance
• Compatible with switches, adapters, and appliances that support OSFP and QSFP56 standards, ensuring broad interoperability
• Built to meet the demands of InfiniBand HDR networking, supporting high throughput and low latency for demanding workloads
• Integrated optical engines inside connectors maintain signal integrity and reduce points of failure in complex setups

Key specs

• Data rate: 400 Gbit/s aggregated (2x 200 Gbit/s links)
• Connector types: 1x OSFP (400 Gbit/s) to 2x QSFP56 (200 Gbit/s each)
• Cable length: 10 meters
• Technology: Active optical cable (AOC)
• Compatibility: InfiniBand HDR, OSFP and QSFP56 standards

Connectivity and compatibility

This splitter cable is designed to work seamlessly with network switches, adapters, and appliances that expose OSFP and QSFP56 ports. It supports InfiniBand HDR protocols, making it suitable for environments that require high bandwidth and low latency connections. The cable’s active optical design ensures compatibility with existing fiber infrastructure while reducing electromagnetic interference common in copper cabling.

• OSFP port connects to 400 Gbit/s switch or adapter
• Two QSFP56 ports connect to devices running at 200 Gbit/s each
• Supports InfiniBand HDR networking standards

Ideal uses and environments

This cable is well suited to data centers and high performance computing clusters where efficient port utilization and reliable high-speed connections are critical. It fits environments that require flexible cabling across racks or rows without the bulk of copper cables. Users managing dense GPU servers, scale-out storage, or composable infrastructures will find it simplifies network expansion and upgrades without hardware replacement.

By enabling two 200 Gbit/s links from a single 400 Gbit/s port, it supports balanced network topologies and targeted bandwidth increases, making it a strong choice for AI training systems, storage fabrics, and other demanding applications.

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.

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.
