NVIDIA/Mellanox MCP7H00-G004R26L Compatible 100G QSFP28 4 x 25G NRZ to 2 x 50G QSFP28 2 x 25G NRZ Ethernet Passive Copper Breakout Cable, 4m (13ft)

The HT-manufactured MCP7H00-G004R26L compatible cable provides 100G connectivity for NVIDIA/Mellanox equipment. This 4m (13ft) 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 QSFP28-4x 25G-NRZ SFP28-2x 25G-NRZ. 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 4m (13ft) length gives MCP7H00-G004R26L more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

MCP7H00-G004R26L is the longest of 4 verified length options in this family. Compared with MCP7H00-G003R30L at 3m (10ft), it provides 1m 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 0.5W. 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, PVC (OFNR) jacket, minimum bend radius 10D/5D (Dynamic/Static). 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 100G/50G Ethernet, 128G Fibre Channel. Listed interface and protocol references include IEEE 802.3, QSFP28 MSA, SFP-8665, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP28 to 2x SFP28 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.

Compatibility is more than matching the QSFP28 to 2x SFP28 shape. This assembly is prepared for hosts expecting MCP7H00-G004R26L and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

When ordering, specify MCP7H00-G004R26L, cable length 4m (13ft) 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.

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, MCP7H00-G004R26L and the 4m (13ft) 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.
