• Minimum bend radius: 23mm

The listed modulation format is 8x100G-PAM4 to Quad 2x100G-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 1.7W (800G End)0.3W (200G 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 23mm. 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/200G Ethernet. Listed interface and protocol references include CMIS 5.0, IEEE 802.3ck, OSFP MSA Rev 5.0. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 4x OSFP (RHS/Flat Top) 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.

MCA7J70-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.

MCA7J70-N002 occupies the middle of this family between MCA7J70-N001 at 1m (3ft) and MCA7J70-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.

Our compatibility setup for NVIDIA/Mellanox MCA7J70-N002 is checked together with the physical 2m (7ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

When ordering, specify MCA7J70-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.

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.

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.
