Specifications

Power and Thermal Planning

The rated power consumption is 0.1W Per End. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 28mm; the stated power consumption is 0.1W Per End; the jacket material is PVC (OFNR).

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 28mm. 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.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8636, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

Passive Copper Operation

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.

Length Selection and Installation Planning

Longer assemblies require disciplined cable dressing. For QSFP+ to SFP+-40G-DAC-7M23FT at 7m (23ft), use the intended managers rather than a diagonal route across the rack, and leave enough space to release each connector. Any service allowance should be loose and supported, with the complete copper assembly and both connector housings protected throughout the path. The next shorter verified assembly is QSFP+ to SFP+-40G-DAC-5M16FT at 5m (16ft), which is the better comparison when the managed route leaves substantial unused cable.

Position Within the Length Range

QSFP+ to SFP+-40G-DAC-7M23FT is the longest of 6 verified length options in this family. Compared with QSFP+ to SFP+-40G-DAC-5M16FT at 5m (16ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Standard protective packing is used by default, with project documentation arranged when requested.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. Quantity and any labeling instructions should be attached specifically to QSFP+ to SFP+-40G-DAC-7M23FT.

Generic Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.

Frequently Asked Questions

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
