NVIDIA/Mellanox MC220731V-100 Compatible 56G QSFP+ InfiniBand FDR Active Optical Cable, 100m (328ft)

The MC220731V-100 compatible cable combines High-Speed AOC connectivity with a defined 100m (328ft) pathway between QSFP+ to QSFP+ interfaces. It is intended for NVIDIA/Mellanox equipment and is documented here as a distinct order code, allowing cable schedules, service access and related length selections to be reviewed before installation.

Signal and Lane Configuration
The listed modulation format is 4x10.3125Gbps 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.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, QSFP+ MSA, 56G InfiniBand FDR. Confirm that the host firmware and port configuration support the same operating mode.
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
For this 100m (328ft) version, prepare the destination pathway before connecting either end. A longer assembly can cross separated equipment positions, but its weight and service slack must remain supported without blocking airflow. Handle the integrated optical cable and both optical engines as one factory-terminated product and never pull a connector into position by the cable.
Structured Pathways and Serviceability
Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this assembly, the minimum bend radius is 7.5mm; the jacket material is OFNP.
Cable Construction and Routing
This assembly uses OFNP jacket, minimum bend radius 7.5mm. 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.
Ordering Information
Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. This page’s fixed configuration is 100m (328ft); another length must be quoted under its corresponding part number.
NVIDIA/Mellanox Compatibility and Factory Testing
Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
Shipping and Lead Time
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
Quality Assurance and Packaging
After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Standard protective packing is used by default, with project documentation arranged when requested.
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-100.
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.
