Specifications

Power and Thermal Planning

The rated power consumption is ≤1.5W. 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.

Length Selection and Installation Planning

A 7m (23ft) run can remain tidy when its pathway and service allowance are planned together. Keep the complete copper assembly and both connector housings away from tight cable-tie pressure, verify bend control at changes of direction and ensure that neither port supports the assembly’s weight. Record the exact order code after acceptance. The next shorter verified assembly is MCA7J50-H005R at 5m (16ft), which is the better comparison when the managed route leaves substantial unused cable.

Position Within the Length Range

MCA7J50-H007R is the longest of 3 verified length options in this family. Compared with MCA7J50-H005R at 5m (16ft), it provides 2m 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.

High-Density Rack Integration

In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 36.5mm; the stated power consumption is ≤1.5W; the jacket material is PVC (OFNR).

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 36.5mm. 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 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.

Breakout Port Mapping

The QSFP56 to 2x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

Quality Assurance and Packaging

Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Neutral packaging and customer-specific packing documentation are available on request.

Ordering Information

Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. Keep MCA7J50-H007R associated with 7m (23ft) throughout the order and receiving record.

NVIDIA/Mellanox Compatibility and Factory Testing

The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.
