HPE S1J07A 50 Gb/s QSFP56 → SFP56 DAC Cable
Overview
The HPE S1J07A is a 0.65‑meter passive direct‑attach copper (DAC) cable rated for 50 Gb/s. It features a QSFP56 connector on one end and an SFP56 on the other, offering a cost‑effective, low-latency interconnect for high-speed data paths in dense data‑center or switch stacking scenarios. It is commonly used in HPE/Aruba switching environments, especially for short-reach links where fiber cabling is unnecessary. The cable is hot-pluggable and supports reliable operation between compatible 50G devices.
