JL283A

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.
