JL001A HPE X142 40GBase Direct Attach Cable 3.3 ft

JL001A Overview

The HPE is a high-performance 40GBase direct attach cable (DAC) designed for short-reach, 40 Gigabit Ethernet connections between QSFP+ ports on compatible HPE/Aruba switches, routers, or other networking gear. At 3.3 feet (≈1 meter) in length, it uses twinax copper with QSFP+ connectors on both ends to deliver low-latency, low-power, and cost-effective 40 GbE links without the need for separate optical transceivers or fiber cabling ideal for in-rack or adjacent-rack interconnects in data centers and enterprise networks. As a direct attach solution, the cable supports standards-based 40GBASE-CR4 performance and plug-and-play deployment, helping simplify high-speed cabling while maintaining robust signal integrity.
