Description

The JG329A-BCC is a drop-in compatible replacement for the Aruba JG329A. This 1-meter passive copper breakout cable provides plug-and-play compatibility with Aruba network switches requiring a 40GBASE-CR4 to 4x10GBASE-CU connection. - Complies with SFF-8436 MSA specification and 40GBASE-CR4 to 4x10GBASE-CU standards, ensuring interoperability with standard Aruba QSFP+ and SFP+ ports - Passive direct attach copper twinax design: one 40G QSFP+ connector breaks out to four 10G SFP+ connectors for flexible top-of-rack connectivity - 1-meter total cable length with 30AWG copper conductors for low-latency, short-reach applications within and across racks - Supports 40Gbps aggregate throughput split into four independent 10Gbps lanes - Fully shielded passive twinax construction eliminates the need for external power or transceivers, reducing cost and power consumption

Features

• 40GBASE-CR4 and SFF-8436 MSA compliance guarantees electrical and mechanical interoperability with standard QSFP+ ports and breakout mode operation to 10GBASE-CU SFP+ interfaces
• Four independent 10Gbps electrical lanes enable flexible port mapping: connect a single 40G uplink to four separate 10G devices without additional switching hardware
• Passive copper design eliminates active components, transceivers, and external power requirements, reducing per-port cost and total system power draw compared to optical solutions
• 30AWG twinax construction provides sufficient signal integrity for 1-meter reach while maintaining cable flexibility for dense rack installations and tight bend radius requirements
• Hot-swappable QSFP+ and SFP+ connectors support installation and removal without powering down the host switch, enabling maintenance without network downtime
• Fully shielded twinax cable minimizes crosstalk and EMI in high-density environments with multiple parallel cable runs

FAQs

Q: Will this work in place of the Aruba JG329A?
A: Yes. The JG329A-BCC provides the same 40GBASE-CR4 to 4x10GBASE-CU electrical interface, 1-meter passive twinax construction, and SFF-8436 MSA-compliant QSFP+ and SFP+ connectors as the Aruba JG329A. It is plug-and-play compatible with Aruba switches that specify the JG329A for 40G-to-4x10G breakout connectivity.

Q: Which Aruba switch platforms support this cable?
A: This cable works with any Aruba switch featuring standard QSFP+ 40G ports that support 40GBASE-CR4 operation and breakout mode to four 10GBASE-CU SFP+ interfaces. Compatibility is determined by the switch port supporting the 40GBASE-CR4 and 10GBASE-CU copper standards, not by specific model numbers. Consult your switch documentation to confirm QSFP+ breakout capability.

Q: Can the four 10G SFP+ connectors operate independently at different speeds?
A: No. The cable is designed for four independent 10Gbps lanes only. Each SFP+ leg carries a dedicated 10Gbps electrical signal derived from the 40Gbps QSFP+ aggregate. The lanes are electrically independent for device connectivity, but each must negotiate at 10Gbps. Mixed-speed operation is not supported by the 40GBASE-CR4 to 4x10GBASE-CU standard.

Q: What is the maximum reach limitation for passive copper breakout cables?
A: This 1-meter passive twinax cable is suitable for intra-rack and short adjacent-rack connections. Passive copper cables beyond 5 meters typically experience signal attenuation that degrades link quality at 10Gbps per lane. For longer distances, consider active copper or active optical breakout cables, which include signal amplification or optical transmission to extend reach without degradation.

Q: Does this cable support forward error correction (FEC)?
A: FEC operation is determined by the host switch port configuration, not the cable. This passive copper cable transparently passes electrical signals compliant with 40GBASE-CR4 and 10GBASE-CU standards. If the switch enables FEC for the QSFP+ port or the breakout SFP+ interfaces, the cable will carry the FEC-encoded data without modification. Check your switch configuration to enable or verify FEC settings.
