NVIDIA/Mellanox MCA4J80-N002 Compatible 800G Twin-port OSFP 8 x 100G PAM4 IHS/Finned Top InfiniBand NDR Active Copper Twinax Cable, 2m (7ft)

For short, high-density connections, this ACC cable combines 800G performance with a fixed 2m (7ft) cable run. It corresponds to NVIDIA/Mellanox MCA4J80-N002 and uses an actively conditioned copper link for the stated high-speed interface.

The listed modulation format is 8x100G-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.

The intended application is 800G InfiniBand. Listed interface and protocol references include CMIS 5.0, IEEE 802.3ck, OSFP Rev5.0. Confirm that the host firmware and port configuration support the same operating mode.

MCA4J80-N002 provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

MCA4J80-N002 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 MCA4J80-N004 at 4m (13ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The rated power consumption is 1.3W 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.

This assembly uses 30AWG conductors, PET jacket, minimum bend radius 48.5mm. 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.

The assembly is configured for equipment that recognizes MCA4J80-N002. 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.

This product is ordered as MCA4J80-N002 in 2m (7ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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, MCA4J80-N002 and the 2m (7ft) length for easier inventory control.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
