NVIDIA MCP1600-E001E30

Overview

The NVIDIA MCP1600-E001E30 is a QSFP28 passive Twinax copper cable designed to deliver reliable 100Gb/s data transmission over a 1-meter length. It supports InfiniBand EDR and Ethernet systems by using four 25Gb/s lanes within 30AWG conductors, making it an efficient choice for short-distance, high-bandwidth connections in data centers and server racks.

This cable is ideal for linking top-of-rack switches to servers, creating spine-to-leaf network topologies, wiring storage arrays, or connecting GPU clusters where full bandwidth is essential but distances remain short. Its passive design requires no additional power and keeps complexity low, while the low smoke zero halogen jacket ensures safe routing in dense or enclosed environments.

Key features

• Passive QSFP28 to QSFP28 connection that simplifies installation and reduces power consumption
• Supports 100Gb/s total data rate through four 25Gb/s differential pairs for high-speed networking
• Built-in EEPROM provides automatic recognition of cable length and capabilities, easing inventory management and configuration
• Compliance with SFF-8665 mechanical and SFF-8636 management standards ensures compatibility and reliability
• Low smoke zero halogen (LSZH) jacket enhances safety when routing cables in enclosed racks or data halls
• 1-meter length optimized to maintain signal integrity and minimize insertion loss for critical network links

Key specs

• Data rate: 100Gb/s total (4 lanes at 25Gb/s each)
• Cable length: 1 meter
• Conductor gauge: 30AWG
• Connector type: QSFP28 to QSFP28
• Standards compliance: SFF-8665 (mechanical), SFF-8636 (management)
• Jacket type: Low smoke zero halogen (LSZH)
• Integrated EEPROM for system-level data reporting

Connectivity and compatibility

This cable is designed to connect devices equipped with QSFP28 ports, commonly found in high-performance switches, servers, and storage systems. Its adherence to SFF-8665 and SFF-8636 standards guarantees seamless integration with InfiniBand EDR and Ethernet networks operating at 100Gb/s speeds. The passive Twinax design suits environments where devices are within a short distance, typically inside racks or data center rows.

Ideal uses and environments

The NVIDIA MCP1600-E001E30 fits well in data centers requiring efficient, high-speed interconnects without the added cost or power demands of optical transceivers. It works effectively for network engineers building spine-leaf architectures, IT teams linking storage arrays, and GPU cluster setups where bandwidth and low latency are critical. Its LSZH jacket makes it suitable for enclosed or densely populated racks where fire safety standards are a priority.

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.

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.
