NVIDIA/Mellanox MC220731V-050 Compatible 56G QSFP+ Ethernet Active Optical Cable, 50m (164ft)

For buyers working from an equipment parts list, MC220731V-050 identifies more than a connector style. It refers here to a 50m (164ft) AOC cable for NVIDIA/Mellanox hosts, supporting High-Speed operation with QSFP+ to QSFP+. The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Cable Construction and Routing
This assembly uses OFNP jacket, minimum bend radius 30mm. 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.
Integrated Optical Assembly
The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.
Length Selection and Installation Planning
With 50m (164ft) available, the installer has more routing freedom but also more cable to control. Determine where any remaining service loop will be stored, preserve the stated bend radius and keep the loop away from sharp edges and hot exhaust. The integrated optical cable and both optical engines should remain accessible for inspection and removal. The next shorter verified assembly is MC220731V-030 at 30m (98ft), which is the better comparison when the managed route leaves substantial unused cable.
Position Within the Length Range
MC220731V-050 is the longest of 10 verified length options in this family. Compared with MC220731V-030 at 30m (98ft), it provides 20m 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.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 56G InfiniBand , 4x FDR, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
NVIDIA/Mellanox Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. Keep MC220731V-050 associated with 50m (164ft) throughout the order and receiving record.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. Neutral packaging and customer-specific packing documentation are available on request.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MC220731V-050.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
