For short reach 800Gbps links in InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable offers a factory terminated passive breakout dac assembly with 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) connectors and a length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets OSFP MSA, IEEE 802.3ck, CMIS v4.0.

In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable provides a factory terminated 800Gbps link between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports. This unit is available in 6 standard lengths from 0.5m (2ft) to 3m (10ft). The breakout design lets one high speed port feed 2x 400G OSFP (IHS/Finned Top), which raises port utilization and simplifies cabling in dense rows. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 100G PAM4 to Dual 4x 100G PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, IEEE 802.3ck, CMIS v4.0. 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.

The standard part number of this assembly is OSFP-800G-2OPC. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
