NVIDIA/Mellanox MCA7J50-H003R Compatible 200G QSFP56 4 x 50G PAM4 to 2 x 100G QSFP56 2 x 50G PAM4 Ethernet Active Copper Breakout Cable, 3m (10ft)

This HT cable matches the MCA7J50-H003R requirement for NVIDIA/Mellanox equipment. The 3m (10ft) assembly supports 200G operation and provides an actively conditioned copper link for the stated high-speed interface; its complete electrical and mechanical details are listed below.

OEM Part Number: MCA7J50-H003RHT Part Number: MCA7J50-H003R

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MCA7J50-H003R
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to 2x QSFP56
• Fixed length and part number: 3m (10ft), MCA7J50-H003R
• Cable construction: Active Twinax
• Conductor specification: 30AWG
• Maximum power consumption: ≤1.5W
• Minimum bend radius: 27.5mm

The rated power consumption is ≤1.5W. 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.

The QSFP56 to 2x QSFP56 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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

MCA7J50-H003R is the shortest of 3 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 MCA7J50-H005R at 5m (16ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 27.5mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd, SFF-8665, QSFP MSA, SFF-8679, SFF-8636, InfiniBand HDR. Confirm that the host firmware and port configuration support the same operating mode.

Our compatibility setup for NVIDIA/Mellanox MCA7J50-H003R is checked together with the physical 3m (10ft) 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.

This product is ordered as MCA7J50-H003R in 3m (10ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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, MCA7J50-H003R and the 3m (10ft) 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.
