MCA1J00-H007ENVIDIA/Mellanox MCA1J00-H007E Compatible 200G QSFP56 4 x 50G PAM4 InfiniBand HDR Active Copper Twinax Cable, 7m (23ft)
For densely populated equipment, the fixed 7m (23ft) version of NVIDIA/Mellanox MCA1J00-H007E offers a clearly defined 200G link without separate optical modules or patch cords. The ACC assembly uses QSFP56 to QSFP56; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

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.
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 44.5mm; the stated power consumption is 1.5W Per End; the jacket material is PVC (OFNR).
Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 44.5mm. 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.
Length Selection and Installation Planning
The 7m (23ft) reach of MCA1J00-H007E is useful only when the managed pathway requires it; straight-line distance between ports is not a sufficient measurement. Check the route around rack rails, cable managers and maintenance clearances, then protect the complete copper assembly and both connector housings from tight bends and unsupported spans. The next shorter verified assembly is MCA1J00-H003E at 3m (10ft), which is the better comparison when the managed route leaves substantial unused cable.
Position Within the Length Range
MCA1J00-H007E is the longest of 2 verified length options in this family. Compared with MCA1J00-H003E at 3m (10ft), it provides 4m 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.
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. Standard protective packing is used by default, with project documentation arranged when requested.
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 MCA1J00-H007E 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. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MCA1J00-H007E.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production quantities confirmed at order stage. 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.
