The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable provides an 800Gbps copper connection between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports with a cable length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 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 is an 800Gbps direct attach copper cable for 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is provided in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 2x 400G OSFP (IHS/Finned Top), it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. 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.
This assembly is listed under part number OSFP-800G-2OPC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom lengths beyond the standard range are available on request. Wire gauge: 28AWG.
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.
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
