Product information

Description

The HPE 100Gb QSFP28 to 4x25Gb SFP28 3m Direct Attach Copper (DAC) cable is a high-performance networking solution engineered for seamless connectivity in modern data centers. This breakout cable allows for the transition from a 100Gb QSFP28 port to four individual 25Gb SFP28 ports, facilitating efficient high-speed data transmission across server and switch infrastructure. With a length of 3 meters, it offers the necessary reach for rack-level interconnections while maintaining signal integrity and low latency performance required for demanding enterprise IT environments.

Advantages

This direct attach copper cable provides a cost-effective and energy-efficient alternative to optical transceivers for short-reach applications. By utilizing a passive copper design, it eliminates the need for additional power consumption at the connection point, which helps in reducing overall data center operational costs. The cable is built to ensure reliable data throughput and minimal signal degradation, making it a dependable choice for high-density networking setups where consistent performance is critical for maintaining uptime and network stability.

Suitable for

High-speed server-to-switch connectivity
Data center rack-to-rack networking
High-density breakout configurations
Enterprise cloud service infrastructure

This cable may not be suitable for long-distance networking requirements, as its passive copper design is optimized for short-reach connections within a single rack or adjacent racks. It is also not compatible with equipment that does not support the QSFP28 or SFP28 interface standards.

Key specifications

Cable length: 3 meters
Connector 1: QSFP28
Connector 2: 4x SFP28
Data transfer rate: 100 Gbit/s
Cable type: Direct Attach Copper (DAC)

How to use

To install the cable, ensure that both the QSFP28 port on your switch or server and the four SFP28 ports on the target devices are powered off or configured for the breakout mode. Insert the QSFP28 connector into the primary port until it clicks into place, then connect each of the four SFP28 ends into the corresponding network interface cards or switch ports. Once connected, power on the equipment and verify the link status through your network management software to ensure proper data transmission.

What to consider before purchase

Verify that your hardware supports 100Gb to 4x25Gb breakout functionality
Ensure the 3-meter length is sufficient for your specific rack layout
Check compatibility with your existing HPE networking equipment

Usage recommendations: Always handle the cable with care to avoid sharp bends or physical damage to the copper conductors. Ensure that the cable is properly routed through cable management systems to prevent strain on the connectors and to maintain optimal airflow within the server rack.
