Specifications

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 37.5mm. 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 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

Length Selection and Installation Planning

Choose QSFP-H40G-ACU7M when the measured managed path justifies 7m(23ft), not simply to leave a large spare coil. Additional reach can simplify adjacent-rack routing, yet unused cable still needs bend-safe storage and ventilation clearance. Keep identification visible so this extended version is not confused with shorter spares. The next verified reach is QSFP-H40G-ACU10M at 10m (33ft), but selecting it before measuring the route would introduce additional slack to support.

Position Within the Length Range

QSFP-H40G-ACU7M is the shortest of 2 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is QSFP-H40G-ACU10M at 10m (33ft), adding 3m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Mixed-Vendor Network Operation

A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 37.5mm; the jacket material is PVC (OFNR).

Cisco Compatibility and Factory Testing

Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.

Ordering Information

For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. Quantity and any labeling instructions should be attached specifically to QSFP-H40G-ACU7M.

Quality Assurance and Packaging

Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Neutral packaging and customer-specific packing documentation are available on request.

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.
