Description

The DAC-QSFP-4SFP-10G-xM-BCC is a drop-in compatible replacement for the Dell DAC-QSFP-4SFP-10G-1M. This passive twinax breakout cable connects a single 40GB QSFP+ port to four independent 10GB SFP+ ports and works plug-and-play in Dell networking equipment. - IEEE 802.3ba 40GBASE-CR4 and 10GBASE-CU compliance ensures standards-based interoperability across 40GB and 10GB Ethernet infrastructure - QSFP+ MSA SFF-8436 and SFP+ MSA SFF-8431 compliant connectors guarantee form factor compatibility - Four independent 10.3125 Gbps lanes provide 40 Gbps aggregate bandwidth for connecting 40GB switches to 10GB uplinks - Passive copper twinax construction reduces power consumption compared to active optical alternatives - Available in 1M, 3M, and 5M lengths for flexible rack and adjacent rack deployments - Hot-pluggable design supports insertion and removal without powering down equipment

Features

• IEEE 802.3ba 40GBASE-CR4 compliance on the QSFP+ side and 10GBASE-CU on each SFP+ lane ensures each of the four 10GB channels operates independently and can be connected to separate upstream switches or devices
• QSFP+ MSA SFF-8436 38-pin and SFP+ MSA SFF-8431 20-pin connector compliance guarantees mechanical and electrical compatibility with Dell QSFP+ and SFP+ port specifications without adapter requirements
• Passive twinax architecture eliminates the need for power-consuming active signal conditioning, reducing thermal load in dense top-of-rack and storage configurations where every watt matters
• Four independent differential pairs allow each 10GB SFP+ channel to carry distinct data streams, enabling 40GB-to-10GB fanout for connecting high-bandwidth core switches to multiple access-layer devices
• 30AWG twinax copper construction balances cable flexibility for routing in tight spaces with signal integrity sufficient for lengths up to 5 meters without forward error correction
• Commercial temperature rating of 0°C to 70°C supports standard data centre environments and most enterprise networking closet conditions
• Hot-swap capability allows field insertion and removal during live operation without requiring host port shutdown, minimizing service interruption during upgrades or troubleshooting

FAQs

Q: Will this work in place of the Dell DAC-QSFP-4SFP-10G-1M?
A: Yes. This cable is a direct plug-and-play replacement for the Dell DAC-QSFP-4SFP-10G-1M. It conforms to the same IEEE 802.3ba 40GBASE-CR4 and 10GBASE-CU standards, uses identical QSFP+ and SFP+ MSA-compliant connectors, and delivers the same 40 Gbps aggregate data rate across four independent 10.3125 Gbps lanes.

Q: What Dell equipment will this cable work with?
A: This cable works with any Dell switch, router, or server equipped with QSFP+ 40GB ports on one end and SFP+ 10GB ports on the other. The QSFP+ end requires a 40GBASE-CR4 capable port, and each of the four SFP+ ends requires a 10GBASE-CU capable SFP+ port. Compatibility is determined by port standard support, not specific platform models.

Q: Can I connect all four SFP+ ends to different switches or devices?
A: Yes. Each of the four SFP+ lanes is electrically and logically independent, transmitting a separate 10 Gbps data stream. You can connect each SFP+ connector to a different upstream switch, server, or storage device. The host QSFP+ port typically presents these as four separate 10GB interfaces that the operating system or switch OS can configure independently.

Q: Does this passive cable require forward error correction or special settings?
A: No. At lengths up to 5 meters, this passive twinax cable operates within the signal integrity margins defined by the 40GBASE-CR4 and 10GBASE-CU specifications without requiring FEC. The cable relies on the differential signaling and impedance matching inherent in the twinax construction. Most Dell platforms auto-negotiate the link without manual configuration.

Q: What is the maximum bend radius for this twinax cable?
A: The recommended minimum bend radius for 30AWG passive twinax cables is typically 4 times the cable diameter, or approximately 25mm to 30mm during installation. Tighter bends can stress the copper pairs and degrade signal integrity, potentially causing bit errors or link instability. Route the cable with gentle curves, especially near the connectors where strain relief is critical.
