NVIDIA InfiniBand Compatible 1.6T OSFP224 Active DAC Cable

The NVIDIA InfiniBand Compatible 1.6T OSFP224 Active DAC Cable, 1.1m provides a 1600Gbps copper connection between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports with a cable length of 1.1m (3.6ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for next generation InfiniBand XDR fabrics and large scale AI clusters.

Product Highlights

• OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)
• Data rate: 1600Gbps
• Cable type: Active DAC (ACC)
• Length: 2 standard lengths between 1.5m (5ft) to 2m (7ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

In next generation InfiniBand XDR fabrics and large scale AI clusters, the NVIDIA InfiniBand Compatible 1.6T OSFP224 Active DAC Cable, 1.1m provides a factory terminated 1600Gbps link between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports. This unit is provided in 2 standard lengths from 1.5m (5ft) to 2m (7ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCA4K50-X001. The link runs 8x 200G-PAM4 to 8x 200G-PAM4 modulation, which keeps it aligned with current 1.6T switch silicon.

This product is designed and tested to comply with OSFP Rev 5.2, IEEE 802.3df, IEEE 802.3dj, CMIS 5.0. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MCA4K50-X001.

This assembly is listed under part number OSFP-1.6T-AC. The cable is supplied in 1.5m (5ft) and 2m (7ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
