NVIDIA MFA7U40-H005

Overview

The NVIDIA MFA7U40-H005 is a 5-meter active optical cable designed to connect one OSFP port to two QSFP56 ports, delivering up to 200 Gbit/s of total throughput. It uses two independent 100 Gbit/s channels with 50G PAM4 signaling to support high-bandwidth workloads in data centers and high-performance computing clusters. The cable’s fiber optic construction ensures signal integrity over the full 16.4-foot length while remaining lightweight and flexible for easy routing in dense rack environments.

Key features

• Active optical technology regenerates signals to maintain consistent quality across the full cable length
• Dual 100 Gbit/s channels enable efficient splitting of a 200 Gbit/s OSFP connection into two QSFP56 ports
• Flexible jacket design allows smooth routing through crowded racks and overhead trays without adding strain
• Immunity to electromagnetic interference reduces noise and improves overall network reliability
• HDR support ensures compatibility with modern NVIDIA networking equipment and other high data rate fabrics
• Plug-and-play operation eliminates the need for additional transceivers, cleaning kits, or special tools

Key specs

• Data rate: up to 200 Gbit/s total throughput
• Channel configuration: 2x100 Gbit/s over 50G PAM4 signaling
• Length: 5 meters (16.4 feet)
• Connector types: 1x OSFP to 2x QSFP56
• Cable type: active optical cable (AOC)

Connectivity and compatibility

This cable is designed to link an OSFP port on a switch or adapter to two QSFP56 ports on servers or additional switches. Its HDR readiness ensures seamless integration with NVIDIA networking gear and other compatible devices that support high data rate fabrics. The active optical design supports stable connections in environments where electromagnetic interference might otherwise degrade performance.

Ideal uses and environments

The MFA7U40-H005 fits well in hyperscale data centers, AI training clusters, and enterprise backbones where high throughput and reliable signal quality are critical. Its flexible and lightweight fiber optic construction makes it suitable for dense rack setups and overhead cable trays, helping maintain airflow and reduce port strain. This cable is a strong choice for IT professionals looking to expand or upgrade their network infrastructure with minimal complexity.

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.

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.
