NVIDIA/Mellanox MCP7Y00-N002 Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top to 2 x 400G OSFP 4 x 100G PAM4 RHS/Flat Top InfiniBand NDR Passive Copper Breakout Cable, 2m (7ft)

Designed for hosts that recognize MCP7Y00-N002, this 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top) cable delivers 800G transmission over a fixed 2m (7ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is 8x 100G-PAM4 to Dual 4x 100G-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 800G OSFP (IHS/Finned Top) to 2x 400G 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.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

MCP7Y00-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.

MCP7Y00-N002 is the longest of 4 verified length options in this family. Compared with MCP7Y00-N01A at 1.5m (5ft), it provides 0.5m 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 0.1W @800G, 0.1W @400G. 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 72mm. 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 NDR. Listed interface and protocol references include OSFP MSA Rev5.0, IEEE 802.3ck, CMIS 4.0. Confirm that the host firmware and port configuration support the same operating mode.

For this NVIDIA/Mellanox application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Use part number MCP7Y00-N002 for the 2m (7ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

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, MCP7Y00-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.
