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.

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.

Structured Pathways and Serviceability

Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. 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.

Ordering Information

Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. This page’s fixed configuration is 1m (3ft); another length must be quoted under its corresponding part number.

Generic Compatibility and Factory Testing

Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.

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. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.

Quality Assurance and Packaging

After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Standard protective packing is used by default, with project documentation arranged when requested.
