Tripp Lite N280-04M-28-BK SFP28 25gbase-cu Dac Cable 4M

Product Description

The TRIPP LITE N280-04M-28-BK is a passive Direct Attach Copper (DAC) cable built to the SFP28 form factor and rated for 25GBase-CU operation. At 4 meters in length, it provides a high-density, low-latency interconnect solution for short-reach 25 Gigabit Ethernet links inside data center racks and top-of-rack switching environments. The cable uses integrated SFP28 transceivers on each end, eliminating the need for separate optical modules. Network engineers and data center technicians install this type of cable to connect servers, switches, and storage nodes where copper DAC is preferred over active optical cabling for cost and power efficiency.

This cable is suited for enterprise data center deployments requiring 25GbE connectivity between adjacent racks or within the same rack row. It is appropriate for use in structured cabling environments where SFP28-compatible ports are present on top-of-rack switches, server NICs, or storage array controllers. The 4-meter reach covers most same-rack and adjacent-rack runs without requiring active components. Installation is handled by network technicians and data center infrastructure personnel.

Key Features

• SFP28 connectors on both ends for 25GbE passive copper connectivity
• 25GBase-CU rated for 25 Gigabit Ethernet over direct attach copper
• 4-meter cable length suitable for same-rack and adjacent-rack runs
• Passive design draws no additional power from host switch ports
• Integrated transceiver modules eliminate separate optic purchases

Compatibility

Designed as an OEM-style passive DAC cable for use with SFP28-compatible 25GbE ports on switches, server network interface cards, and storage array controllers.

Installation Notes

Installation is performed by qualified network technicians or data center personnel. Power down or gracefully disable the relevant switch port before seating or removing the SFP28 connector to avoid potential ESD damage. Ensure the latch mechanism is fully seated and locked before powering the port back on. Follow site-specific cable management and bend-radius guidelines to avoid mechanical stress on the integrated connectors.
