HPE 100GB QSFP28 3m InfiniBand Fibre Optic Cable QSFP+ 4x QSFP+

The HPE 100GB QSFP28 3m InfiniBand cable is a high-performance direct attach solution designed to facilitate rapid data transmission within modern data center environments. By providing a reliable 100 Gb connection, this cable supports the increasing demands of cloud-based services and high-density networking infrastructures. Its design allows for the aggregation of separate 25 Gb connections, offering a versatile breakout configuration that simplifies complex cabling architectures while maintaining signal integrity over a 3-meter distance.

Advantages

This cable offers a significant performance boost by delivering speeds four times faster than standard 25 Gb connections. It is engineered to optimize switch port density, which helps in reducing overall operational costs and power consumption within the server room. By consolidating bandwidth, it effectively minimizes cabling clutter, which in turn improves airflow and cooling efficiency. Furthermore, it serves as a cost-effective alternative to traditional fiber optic cabling for short-reach 100 Gb connectivity, providing a seamless transition path for network upgrades.

Suitable for

• High-speed data center networking
• Cloud-based service infrastructure
• Aggregation of 25 Gb server connections to 100 Gb switches
• High-performance computing clusters

This cable may not be suitable for long-distance networking requirements, as its 3-meter length is specifically optimized for short-range connections within a rack or between adjacent cabinets. It is also not intended for use with non-QSFP28 or non-SFP28 compatible hardware interfaces.

Key specifications

• Data transfer rate: 100 Gbps
• Cable length: 3 meters
• Connector type: QSFP28 to 4x SFP28 breakout
• Technology: Direct Attach Copper (DAC)

To use this cable, ensure that both the switch and the server ports are compatible with the QSFP28 and SFP28 standards. Simply insert the QSFP28 connector into the high-speed switch port and connect the four individual SFP28 ends into the corresponding server network interface cards. The cable is designed for plug-and-play operation, requiring no additional configuration for physical connectivity, though port settings may need to be adjusted in the network management software to recognize the breakout configuration.

What to consider before purchase

• Verify the compatibility of your existing switch and server hardware
• Ensure the 3-meter length is sufficient for your rack layout
• Confirm that your network equipment supports 100 Gb to 4x 25 Gb breakout functionality

Ensure that the cable is routed with appropriate bend radii to prevent physical damage to the internal copper conductors and to maintain optimal signal performance over the long term.
