Product Description
This HP JL283A DAC cable enables direct, high-speed connections between a QSFP28 port and four SFP28 ports, breaking out a single 100Gbps link into four 25Gbps channels. It is often found in data center environments where space and power efficiency matter, offering reliable and low-latency connectivity without the need for separate transceivers. Built for network engineers and IT professionals managing HP X240 series switches, this 3-meter cable fits well in rack setups needing short-range but high-bandwidth connections. It’s commonly used to link switches, servers, or storage devices within the same rack or adjacent racks. Key Features Supports 100Gbps QSFP28 to four 25Gbps SFP28 breakout connections 3 meters length suited for short-distance patching in racks Direct attach copper design reduces power use and latency Compatible with HP X240 and other QSFP28-enabled devices Plug-and-play with no additional transceivers required In practice, this cable is typically deployed in dense data center racks where efficient cabling aids airflow and reduces equipment complexity. It helps streamline network layouts by consolidating multiple lower-speed links into a single cable run, making it easier to manage high-throughput connections within limited space.

Use Cases
The HP JL283A DAC cable is commonly deployed in network racks within data centers and enterprise IT environments where high-density breakout connections are essential. It benefits network administrators and infrastructure engineers who require efficient, scalable solutions for segmenting 100Gbps links into multiple 25Gbps channels to support diverse workloads and virtualization platforms. How It's Used: Breaking out a 100Gbps uplink from core switches to multiple 25Gbps access switches in hyper-converged infrastructure setups. Enabling high-speed connectivity among storage clusters in enterprise data centers to optimize throughput for database and backup workloads. Connecting top-of-rack (ToR) switches to compute nodes in virtualization environments with dense server deployments. Facilitating low-latency inter-switch links within edge computing facilities that require compact cabling solutions. Supporting bandwidth aggregation for SMB network segments that demand cost-effective 25Gbps channels derived from existing 100Gbps QSFP28 ports. This breakout cable design streamlines cabling complexity while reducing power draw, allowing IT teams to scale network capacity efficiently. Its use in rack-level deployments enhances performance consistency and supports the evolving demands of high-throughput applications.
