HPE Networking X240 QSFP28 4xSFP28 3m Direct Attach Copper Cable

Overview

The HPE JL283A is a three-meter direct attach copper cable designed to connect a single QSFP28 port to four SFP28 ports, providing a simple and efficient way to break out high-speed switch ports into individual server, storage, or uplink connections. This cable supports short-range, high-speed networking without the need for additional transceivers or external power, making it a practical choice for data centers where power efficiency and space are critical. Its length of approximately ten feet fits well within rack environments, enabling reliable connections between top-of-rack switches and nearby equipment.

Key features

• Breaks out one QSFP28 port into four separate SFP28 ports, simplifying network segmentation and device connectivity.
• Operates without external power or additional transceivers, reducing both cost and complexity in network setups.
• Low-profile connectors designed to fit into dense switch line cards, helping maintain clean and organized rack layouts.
• Lightweight construction at about 0.5 kg, making installation and cable management easier for technicians.
• Validated compatibility with HPE FlexFabric 12902E and 5940 series switches ensures seamless integration and reliable performance.
• Compact connector dimensions support tidy routing through cable managers and overhead trays in crowded data center environments.

Key specs

• Cable length: 3 meters (approximately 10 feet)
• Connector type: QSFP28 to 4x SFP28 breakout
• Weight: Approximately 0.5 kg
• Connector dimensions: 1.78 x 7.11 x 1.27 cm
• Compatibility: HPE FlexFabric 12902E and 5940 series switches

Connectivity and compatibility

This cable is specifically designed to work with HPE FlexFabric platforms, including the 12902E and 5940 series switches, providing a reliable breakout solution for high-speed networking environments. It connects a single QSFP28 port to four SFP28 ports, enabling multiple independent 25GbE links from one 100GbE port. This makes it well suited for data center racks where multiple servers or storage devices need direct, high-bandwidth connections without the complexity of fiber optics or additional transceivers.

Ideal uses and environments

The JL283A cable fits well in data center racks where space and power efficiency are priorities. It is a strong choice for short-distance backbone links, hyperconverged infrastructure nodes, or clustered database servers requiring full-speed network access. Its design helps reduce thermal load and power consumption, making it suitable for dense switch environments and setups where minimizing installation time and maintenance is important. Network teams upgrading existing HPE environments or building new leaf-spine fabrics will find this cable a practical and cost-effective option.
