NVIDIA/Mellanox MCA4K50-X001 Compatible 1.6T OSFP224 8 x 200G PAM4 IHS/Finned Top InfiniBand XDR Active Copper Twinax Cable, 1.1m (3.6ft)

This 1.1m (3.6ft) ACC cable is built for NVIDIA/Mellanox equipment requiring the MCA4K50-X001 interface. The 1600Gbps link uses OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) and is supplied as one complete tested assembly.

The listed modulation format is 8x 200G-PAM4 to 8x 200G-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.

This assembly uses 30AWG conductors, PET jacket, minimum bend radius 50mm. 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.

The intended application is 1.6T InfiniBand. Listed interface and protocol references include OSFP Rev 5.2, IEEE 802.3df, IEEE 802.3dj, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.

The additional half metre beyond a one-metre assembly gives MCA4K50-X001 useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

MCA4K50-X001 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 MCA4K50-X01A at 1.5m (5ft), adding 0.4m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The rated power consumption is 2W 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.

The assembly is configured for equipment that recognizes MCA4K50-X001. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Quote HT part number MCA4K50-X001 with the required quantity. The 1.1m (3.6ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, MCA4K50-X001 and the 1.1m (3.6ft) length for easier inventory control.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
