NVIDIA/Mellanox MCA4J80-N005 Compatible 800G Twin-port OSFP 8 x 100G PAM4 IHS/Finned Top InfiniBand NDR Active Copper Twinax Cable, 5m (16ft)

For short, high-density connections, this ACC cable combines 800G performance with a fixed 5m (16ft) cable run. It corresponds to NVIDIA/Mellanox MCA4J80-N005 and uses an actively conditioned copper link for the stated high-speed interface.

• Fixed length and part number: 5m (16ft), MCA4J80-N005
• Cable construction: Active DAC (ACC)
• Conductor specification: 26AWG
• Maximum power consumption: 1.3W Per End
• Minimum bend radius: 59.5mm

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 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 26AWG conductors, PET jacket, minimum bend radius 59.5mm. 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 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.

The 5m (16ft) length gives MCA4J80-N005 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.

MCA4J80-N005 is the longest of 3 verified length options in this family. Compared with MCA4J80-N004 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.

Each MCA4J80-N005 compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended NVIDIA/Mellanox platform should be included with the order.

When ordering, specify MCA4J80-N005, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
