NVIDIA/Mellanox MCA7J65-N002 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, 2m (7ft)

This 2m (7ft) ACC cable is built for NVIDIA/Mellanox equipment requiring the MCA7J65-N002 interface. The 850Gbps (8x 106.25Gbps) link uses OSFP (IHS/Finned Top) to 2x QSFP112 and is supplied as one complete tested assembly.

• Minimum bend radius: 32.5mm

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.

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.

MCA7J65-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.

MCA7J65-N002 occupies the middle of this family between MCA7J65-N001 at 1m (3ft) and MCA7J65-N003 at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

This assembly uses 30AWG conductors, PET jacket, minimum bend radius 32.5mm. 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/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 HT cable carries the compatibility configuration associated with MCA7J65-N002, while its mechanical assembly remains the fixed 2m (7ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new NVIDIA/Mellanox software can request a pre-order check.

When ordering, specify MCA7J65-N002, cable length 2m (7ft) 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.

Every MCA7J65-N002 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 2m (7ft) 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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
