Add-On JG329A-AO 40Gbps QSFP+ to 4xSFP+ Direct Attach Cable

Overview

The Add-On JG329A-AO is a TAA-compliant direct attach copper (DAC) cable designed to break out a single 40Gbps QSFP+ port into four independent 10Gbps SFP+ connections. This cable is essential for network engineers needing to segment high-bandwidth uplinks or connect multiple servers to a 40Gbps switch without requiring transceivers and fiber, reducing both cost and complexity in data center and enterprise environments. Its passive design means no power is consumed, simplifying deployment.

Compatibility

This cable is engineered to be compatible with networking equipment utilizing QSFP+ ports that accept standard breakout configurations. It is designed as a direct replacement for HP JG329A, ensuring interoperability with HP switches and other vendor equipment that support QSFP+ to 4xSFP+ breakout functionality. Specific compatibility extends to switches and network interface cards (NICs) with QSFP+ ports requiring a 40GBASE-CU breakout solution.

Installation Notes

Installation is plug-and-play. Ensure the QSFP+ connector is fully seated in the host port and the four SFP+ connectors are securely inserted into their respective SFP+ ports. The passive copper construction means no configuration is required on the host switch or device. Verify that the connected SFP+ ports are configured for 10Gbps operation.
