Product Features
Technical Overview
This cable operates at a full duplex data transfer rate of 40 Gbit/s, supporting high-bandwidth applications and reducing network bottlenecks. The QSFP+ form factor provides a compact, hot-pluggable interface that is widely adopted in modern high-speed networking equipment.
Constructed with copper twinaxial cabling, it offers inherent advantages for short-reach connections, including lower power consumption compared to active optical solutions and inherent electromagnetic interference characteristics suitable for data center environments. The cable is built to meet industry standards for signal integrity at the specified length.
Key Product Advantages
This DAC cable simplifies network architecture by providing a complete, plug-and-play connectivity solution between QSFP+ ports. It reduces overall cost and complexity by integrating the cable and connector into a single, tested assembly.
Validated Compatibility
Specifically tested and guaranteed for compatibility with HP 5400R zl2 Series switches, ensuring reliable performance and reducing integration risks.
- Guaranteed interoperability
- Reduces deployment uncertainty
Performance and Reliability
Delivers full 40 Gbit/s throughput with the signal integrity required for stable, high-speed data transfers over its 3-meter span.
- Maintains signal integrity
- Supports full bandwidth
Deployment / Use Cases
Ideal for interconnecting switches within the same rack or adjacent racks in data centers, where short-reach, high-speed links are required. The 3-meter length is well-suited for top-of-rack switching configurations and intra-rack connectivity.
Common deployments include linking spine and leaf switches in fabric architectures, establishing high-speed uplinks between aggregation switches, and connecting servers with 40GbE network interfaces to the network fabric. Its compatibility with the HP 5400R zl2 Series makes it a strategic choice for expanding or maintaining networks built on that switch platform.

FAQ
What type of cable is the HPE JH235A?
The HPE JH235A is a Direct Attach Copper (DAC) cable with QSFP+ connectors on both ends. It is a passive copper twinaxial cable designed for short-reach, high-speed 40 Gigabit Ethernet connections, integrating the cable and connectors into a single assembly for reliable plug-and-play operation.
What is the maximum data transfer rate of this cable?
This cable supports a full duplex data transfer rate of 40 Gbit/s (40 Gigabits per second). It is designed to handle high-bandwidth network traffic without bottlenecks, making it suitable for data center interconnects, high-performance computing networks, and enterprise backbone links.
Which HPE switches is this DAC cable compatible with?
The HPE JH235A X242 DAC cable is specifically validated for compatibility with the HP 5400R zl2 Series switches. This ensures guaranteed interoperability and reliable performance when used within networks built on that switch platform, reducing integration risks and deployment issues.
What are the advantages of using a DAC cable over separate transceivers and fiber?
Direct Attach Copper cables offer several advantages: they are typically more cost-effective than optical transceivers and fiber optic cabling, provide lower latency for short-reach connections, consume less power, and simplify deployment by eliminating the need to source and test separate components. They are ideal for distances within a rack or between adjacent racks.
