Tripp Lite SFP28 to SFP28 25GbE Passive Twinax Copper Cable (M/M), SFP-H25G-CU1M Compatible, Black, 1 m (3.3 ft.)

Overview

The Tripp Lite N280-01M-28-BK is a passive SFP28 to SFP28 twinax copper cable designed to deliver 25 Gigabit Ethernet over a short 1 meter distance. It is ideal for connecting switches, servers, or storage arrays in data centers, server rooms, and enterprise closets where low-latency, high-speed links are essential. This cable eliminates the need for separate optical transceivers and fiber patch cords, providing a cost-effective and efficient solution for high-performance networking environments.

Key features

• Supports 25 Gbps data transfer for fast and reliable network connections.
• Passive direct-attach design reduces latency and lowers overall system cost by removing the need for optical transceivers.
• Zinc die-cast connector shells shield against electromagnetic interference, ensuring clean signal transmission in dense rack environments.
• Integrated pull tabs enable quick, tool-free hot swaps, simplifying maintenance and upgrades.
• Complies with SFF-8432 and IEEE 802.3by standards for broad compatibility and reliable performance.
• Compatible with major switch platforms including Cisco, Arista, Dell, Juniper, and Mellanox, allowing IT teams to standardize cabling across vendors.
• Backed by a lifetime limited warranty for long-term confidence in critical network infrastructure.

Connectivity and compatibility

This cable is designed to connect devices equipped with SFP28 ports, commonly found in modern data center switches, servers, and storage arrays. Its direct-attach copper design supports seamless integration with equipment from leading vendors such as Cisco, Arista, Dell, Juniper, and Mellanox. The cable’s compliance with industry standards ensures it works reliably across a wide range of network hardware, making it a versatile choice for mixed-vendor environments.

Ideal uses and environments

The 1 meter length and 25 Gbps speed make this cable well suited for top-of-rack connections where devices are located close together. It excels in virtualized clusters, high-performance computing setups, and enterprise networks that require rapid east-west traffic with minimal latency. Its robust EMI shielding and durable connectors also make it a strong option for dense rack installations where interference and frequent maintenance are concerns.
