NVIDIA/Mellanox MCA7J65-N005 Compatible 800G Twin-port OSFP 8 x 100G PAM4 IHS/Finned Top to 2 x 400G QSFP112 4 x 100G PAM4 InfiniBand NDR Active Copper Breakout Cable, 5m (16ft)

This 5m (16ft) ACC cable is built for NVIDIA/Mellanox equipment requiring the MCA7J65-N005 interface. The 850Gbps (8x 106.25Gbps) link uses OSFP (IHS/Finned Top) to 2x QSFP112 and is supplied as one complete tested assembly.

OEM Part Number: MCA7J65-N005HT Part Number: MCA7J65-N005

• Minimum bend radius: 40mm

The listed modulation format is 8x100G-PAM4 to Dual 4x100G-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 26AWG conductors, PET jacket, minimum bend radius 40mm. 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/400G InfiniBand. Listed interface and protocol references include CMIS 5.0, IEEE 802.3ck, OSFP MSA Rev5.0, Q112 MSA. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 2x QSFP112 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.

The 5m (16ft) length gives MCA7J65-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.

MCA7J65-N005 is the longest of 4 verified length options in this family. Compared with MCA7J65-N003 at 3m (10ft), 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.

The rated power consumption is 1.5W (OSFP End)0.6W (QSFP112 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.

Each MCA7J65-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.

This product is ordered as MCA7J65-N005 in 5m (16ft). 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.

Every MCA7J65-N005 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 5m (16ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
