Dell Networking 332-1663 Compatible 40G QSFP+ Passive Copper Cable, 5m (16ft)

For data-center links that specify Dell Networking 332-1663, this 5m (16ft) DAC assembly delivers 40G connectivity through QSFP+ to QSFP+. It removes separate module-and-patch-cord interfaces while retaining clear mechanical, power and compatibility details for high-density design and installation planning.

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 40mm. 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.

Position Within the Length Range

332-1663 occupies the middle of this family between 331-8160 at 3m (10ft) and CBL-QSFP-40GE-PASS-7M at 7m (23ft). It adds 2m 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.

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 40mm; the jacket material is PVC (OFNR).

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, QSFP+ MSA and IEEE 802.3ba. 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

The 5m (16ft) length gives 332-1663 more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

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. This page’s fixed configuration is 5m (16ft); another length must be quoted under its corresponding part number.

Dell Networking 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

Is this an original Dell Networking cable?

No. It is an HT-manufactured compatible alternative for equipment that specifies Dell Networking 332-1663.

Can different brands be connected with the same assembly?

Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.

Does this order code cover multiple lengths?

No. 332-1663 refers here to 5m (16ft). Every other verified length has a separate part number and page in the length list.

Are separate transceivers or patch leads required?

No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.

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.
