NVIDIA/Mellanox MCP7H70-V00AR30 Compatible 200G QSFP56 4 x 50G PAM4 to 4 x 50G SFP56 50G PAM4 Ethernet Passive Copper Breakout Cable, 0.5m (2ft)

The HT-manufactured MCP7H70-V00AR30 compatible cable provides 200G connectivity for NVIDIA/Mellanox equipment. This 0.5m (2ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

The listed modulation format is QSFP56-4x 50G-PAM4SFP56-50G-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.

MCP7H70-V00AR30 is the shortest of 4 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is MCP7H70-V001R30 at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The rated power consumption is 0.1W (QSFP56 End)0.1W (SFP56 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, PVC (OFNR) jacket, minimum bend radius 35mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include SFF-8661, SFF-8432, IEEE 802.3bs-200GAUI-4, IEEE802.3cd-50GAUI-1, SFP-8636, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP56 to 4x SFP56 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.

The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing MCP7H70-V00AR30; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

Each MCP7H70-V00AR30 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.

Use part number MCP7H70-V00AR30 for the 0.5m (2ft) 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, MCP7H70-V00AR30 and the 0.5m (2ft) 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.
