Specifications

Signal and Lane Configuration

The listed modulation format is 8x 200G-PAM4 to 8x 200G-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.

Cable Construction and Routing

This assembly uses 30AWG conductors, PET jacket, minimum bend radius 50mm. 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 1.6T InfiniBand. Listed interface and protocol references include OSFP Rev 5.2, IEEE 802.3df, IEEE 802.3dj, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.

Length Selection and Installation Planning

The additional half metre beyond a one-metre assembly gives MCA4K50-X001 useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

Position Within the Length Range

MCA4K50-X001 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 MCA4K50-X01A at 1.5m (5ft), adding 0.4m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Rack Layout and Service Access

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air. For this assembly, the listed conductor specification is 30AWG; the minimum bend radius is 50mm; the stated power consumption is 2W Per End; the jacket material is PET.

Power and Thermal Planning

The rated power consumption is 2W 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.

Quality Assurance and Packaging

The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service. Standard protective packing is used by default, with project documentation arranged when requested.

NVIDIA/Mellanox Compatibility and Factory Testing

Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.

Frequently Asked Questions

Ordering Information

When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. This page’s fixed configuration is 1.1m (3.6ft); another length must be quoted under its corresponding part number.

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.
