Specifications

Signal and Lane Configuration

The listed modulation format is OSFP-8x 100G-PAM4QSFP112-4x 100G-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.

Breakout Port Mapping

The OSFP (IHS/Finned Top) to 2x QSFP112 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.

Passive Copper Operation

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.

Length Selection and Installation Planning

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 MCP7Y10-N00A; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

Position Within the Length Range

MCP7Y10-N00A 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 MCP7Y10-N001 at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Mixed-Vendor Network Operation

A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this assembly, the listed conductor specification is 30AWG; the minimum bend radius is 34.5mm; the stated power consumption is 0.1W (OSFP End)0.1W (QSFP112 Per End); the jacket material is PVC.

Power and Thermal Planning

The rated power consumption is 0.1W (OSFP End)0.1W (QSFP112 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.

Cable Construction and Routing

This assembly uses 30AWG conductors, PVC jacket, minimum bend radius 34.5mm. 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.

Network and Protocol Considerations

The intended application is 800G/400G InfiniBand. Listed interface and protocol references include OSFP MSA, QSFP112 MSA, IEEE 802.3ck, CMIS v5.0. Confirm that the host firmware and port configuration support the same operating mode.

NVIDIA/Mellanox Compatibility and Factory Testing

Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.

Ordering Information

For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. Keep MCP7Y10-N00A associated with 0.5m (2ft) throughout the order and receiving record.

Quality Assurance and Packaging

Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Volume orders can include customer references on the labels and carton list.

Frequently Asked Questions

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
