NVIDIA MFA1A00-C005

Overview

The NVIDIA MFA1A00-C005 is an active optical cable designed to deliver 100 Gb Ethernet connectivity using QSFP28 connectors on both ends. It employs VCSEL technology with four multimode fiber transceivers per side, each capable of 25 Gb/s, combining to provide a total bandwidth of 100 Gb/s over distances up to 100 meters. This cable is ideal for data centers and high-performance computing environments where reliable, high-speed connections between servers, switches, and storage devices are essential.

Key features

• Delivers high-speed 100 Gb Ethernet links over multimode fiber for distances up to 100 meters, supporting large-scale network deployments.
• Four 25 Gb/s lanes use VCSEL technology to maintain consistent throughput and low latency across the connection.
• Hot-pluggable QSFP28 connectors simplify installation and maintenance without disrupting network operations.
• Selectable per-lane retiming, programmable input equalizers, and output pre-emphasis enhance signal integrity in electrically noisy environments.
• Low power consumption of approximately 2.2 W per end on a single 3.3 V supply helps meet strict power budgets in dense rack setups.
• Built-in I2C management interface supports real-time monitoring and diagnostics, ensuring reliable operation and easy troubleshooting.
• Compliance with SFF-8665 and SFF-8636 standards guarantees compatibility with a wide range of 100 Gb Ethernet QSFP28 equipment.

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.
