Specifications

Power and Thermal Planning

The rated power consumption is 1.5W 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.

Position Within the Length Range

MCA1J00-H005E is the longest of 2 verified length options in this family. Compared with MCA1J00-H004E at 4m (13ft), it provides 1m 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.

Interoperability and Configuration Checks

Check three layers before deployment: the host must accept the cable identification, the port must support the stated aggregate rate, and the lane configuration must match the attached interfaces. On breakout hardware, also confirm channelization and the mapping of every branch. These checks are particularly important when similar-looking ports operate at different speeds or under different firmware settings. For this assembly, the listed conductor specification is 28AWG; the minimum bend radius is 40mm; the stated power consumption is 1.5W Per End; the jacket material is PVC (OFNR).

Cable Construction and Routing

This assembly uses 28AWG 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.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd, SFF-8665, QSFP MSA, SFF-8679, SFF-8636, InfiniBand HDR. Confirm that the host firmware and port configuration support the same operating mode.

Length Selection and Installation Planning

The 5m (16ft) length gives MCA1J00-H005E more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.

Ordering Information

Specify the OEM part number and fixed length, then provide the intended host configuration if the link uses channelized or breakout ports. Separate part numbers should be used for separate lengths. This gives the compatibility review enough information to check both the physical assembly and the intended operating mode. This page’s fixed configuration is 5m (16ft); another length must be quoted under its corresponding part number.

NVIDIA/Mellanox Compatibility and Factory Testing

The verification process combines digital identification with a live link test and diagnostic observation. Host model, hardware revision and software release are useful inputs because qualification behavior can change between platform generations; those details allow platform-specific requirements to be reviewed before the cable is packed. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. 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

Functional inspection covers identification, link establishment and the condition of both connector assemblies. The cable is then protected against dust and connector damage and packed without sharp bends. Labels can include the customer reference and host-platform note when requested for a controlled deployment. Neutral packaging and customer-specific packing documentation are available on request.
