Intel X4DACBL1 Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 1m (3ft)

This HT cable matches the X4DACBL1 requirement for Intel equipment. The 1m (3ft) assembly supports 40G operation and provides a factory-terminated passive copper link without separate optical modules or patch cords; its complete electrical and mechanical details are listed below.

OEM Part Number: X4DACBL1HT Part Number: X4DACBL1

Product Highlights

• Compatible alternative to Intel X4DACBL1
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 1m (3ft), X4DACBL1
• Conductor specification: 30AWG
• Minimum bend radius: 21mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The QSFP+ to 4 SFP+ configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

At 1m (3ft), X4DACBL1 is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

X4DACBL1 occupies the middle of this family between X4DACBL50 at 0.5m (2ft) and X4DACBL3 at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, SFF-8431 and QSFP+ MSA. Confirm that the host firmware and port configuration support the same operating mode.

For this Intel application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

This product is ordered as X4DACBL1 in 1m (3ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
