Specifications

Signal and Lane Configuration

The listed modulation format is 4x 100G-PAM4. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

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 32AWG; the minimum bend radius is 26.5mm; the stated power consumption is <8W Per End; the jacket material is PET.

Power and Thermal Planning

The rated power consumption is <8W 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.

Cable Construction and Routing

This assembly uses 32AWG conductors, PET jacket, minimum bend radius 26.5mm. 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 QSFP112 MSA, IEEE 802.3ck 400GBase-CR4, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.

Length Selection and Installation Planning

At 1m (3ft), QSFP112 to QSFP112-400G-AEC-1M3FT 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.

Position Within the Length Range

QSFP112 to QSFP112-400G-AEC-1M3FT is the shortest of 3 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 QSFP112 to QSFP112-400G-AEC-2M7FT at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Generic 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. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.

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 QSFP112 to QSFP112-400G-AEC-1M3FT.

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. Standard protective packing is used by default, with project documentation arranged when requested.
