NVIDIA InfiniBand Compatible 800G OSFP Passive DAC

The NVIDIA InfiniBand Compatible 800G OSFP Passive DAC is a passive dac direct attach copper cable with OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top), supporting 800Gbps links over a length of 1.5m (5ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for InfiniBand NDR fabrics, GPU clusters and AI training networks, and complies with OSFP MSA, IEEE 802.3ck, CMIS v4.0.

In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP Passive DAC provides a factory terminated 800Gbps link between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports. This unit is manufactured in 5 standard lengths from 0.5m (2ft) to 3m (10ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Compatibility with NVIDIA/Mellanox InfiniBand systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MCP4Y10-N01A. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, IEEE 802.3ck, CMIS v4.0. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCP4Y10-N01A directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Part number of this model: OSFP-800G-PC. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 26AWG. Samples for testing can be arranged before bulk orders.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed 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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
