The HP JL295A is a 3-meter direct attach copper (DAC) cable designed for 25 Gigabit Ethernet connectivity between SFP28 ports. This passive copper cable delivers full 25G throughput without the cost and power consumption of active optics, making it ideal for high-speed interconnects in data center and enterprise environments. The SFP28 connectors are hot-pluggable and compatible with HP/HPE 25G networking equipment, including switches and network adapters that support the SFP28 form factor. The 3-meter length accommodates typical rack-to-rack or equipment-to-equipment distances in standard data center layouts.Direct attach copper cables provide low-latency, low-cost connectivity for short-reach connections up to approximately 5 meters at full 25G line rates. The JL295A is commonly deployed in high-performance computing clusters, storage area networks (SANs), and Ethernet fabrics where cost-per-gigabit and power efficiency matter. This refurbished unit has been tested and guaranteed to meet HP/HPE specifications. Available via quote.
