Tripp Lite N281-01M-BK

Overview

The Tripp Lite N281-01M-BK is a 1-meter passive direct attach copper breakout cable designed to convert a single QSFP+ 40 GbE port into four independent SFP+ 10 GbE connections. This cable is ideal for expanding bandwidth from spine or aggregation switches to servers, storage devices, or top-of-rack switches within the same cabinet. Supporting an aggregate data rate of up to 40 Gbps, it ensures high-speed data transfer for demanding applications like backups, virtualization, and database replication without adding latency.

Key features

• Splits one QSFP+ 40 GbE port into four separate 10 GbE SFP+ links, increasing port density efficiently
• Passive copper design eliminates the need for external power or transceivers, reducing operating costs
• Zinc die cast connectors shield against electromagnetic interference, maintaining signal integrity in dense data centers
• Pull-tab ejectors provide easy connector insertion and removal in crowded switch panels without special tools
• Flexible eight-pair, 30 AWG conductor design simplifies routing through cable managers and tight spaces
• Complies with MSA SFF-8431 and SFF-8436 standards for broad compatibility with open-standards networking equipment
• Pinout matches Cisco QSFP-4SFP10G-CU1M, ensuring seamless integration in mixed-vendor environments
• Compatible with SDR, DDR, and QDR InfiniBand equipment, supporting high-performance computing clusters

Key specs

Connectivity and compatibility

This breakout cable is designed to work seamlessly with a wide range of networking gear that supports QSFP+ and SFP+ interfaces. Its adherence to industry standards ensures it fits well in multivendor racks and data center environments. The cable’s compatibility with InfiniBand protocols adds versatility for specialized high-performance computing setups.

• QSFP+ 40 GbE port on one end
• Four SFP+ 10 GbE ports on the other end
• Compatible with Cisco and other vendors’ QSFP+ and SFP+ ports
• Supports SDR, DDR, and QDR InfiniBand equipment

Ideal uses and environments

This breakout cable is well suited for data centers and enterprise networks where maximizing port density and reducing costs are priorities. It works effectively for connecting hyper-converged servers, iSCSI storage targets, or providing redundant uplinks to access layer switches. Its passive design and flexible construction make it a practical choice for installations requiring clean cable management and minimal power consumption.

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.
