NVIDIA MMS1W50-HM

Overview

The NVIDIA MMS1W50-HM is a LinkX QSFP56 transceiver designed to deliver 200 Gbps Ethernet throughput, making it a strong choice for modern data centers handling AI, high-performance computing, and cloud workloads. It connects via single-mode fiber using a standard LC interface and supports distances up to 2 kilometers at a 1310 nm wavelength, ensuring reliable long-reach connectivity.

This transceiver follows the 200GBase-FR4 Ethernet protocol, allowing seamless integration into Ethernet switching networks, storage fabrics, and GPU-accelerated clusters. It helps maintain consistent data flow by eliminating bottlenecks between compute, storage, and accelerator nodes during peak demand periods.

Connectivity and compatibility

This transceiver is designed to fit into QSFP56 cages commonly found in high-speed Ethernet switches and network adapters. It supports standard single-mode fiber connections via LC connectors, making it compatible with existing fiber optic cabling in data centers. Its adherence to the 200GBase-FR4 protocol ensures it works smoothly within Ethernet switching fabrics, storage networks, and GPU clusters without requiring changes to cable infrastructure.

Ideal uses and environments

The MMS1W50-HM is well suited to data centers focused on AI training, high-performance computing, and cloud services that demand high throughput and low latency. It works effectively in leaf-spine network architectures, storage replication between data halls, and scaling AI supercomputers. Network engineers looking to upgrade bandwidth while minimizing power and space consumption will find this transceiver a practical and efficient solution.

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.
