The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G QSFP112 4x 100G PAM4 InfiniBand NDR Active Breakout DAC Cable provides an 850Gbps (8x 106.25Gbps) copper connection between OSFP (IHS/Finned Top) to 2x QSFP112 ports with a cable length of 1m (3ft). 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 InfiniBand NDR fabrics, GPU clusters and AI training networks.

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G QSFP112 4x 100G PAM4 InfiniBand NDR Active Breakout DAC Cable is an 850Gbps (8x 106.25Gbps) active copper cable for OSFP (IHS/Finned Top) to 2x QSFP112 connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is provided in 5 standard lengths from 1m (3ft) to 5m (16ft). One port becomes 2x QSFP112, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCA7J65-N001. The link runs 8x100G-PAM4 to Dual 4x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MCA7J65-N001 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers CMIS 5.0, IEEE 802.3ck, OSFP MSA Rev5.0, Q112 MSA.
This assembly is listed under part number OSFP-800G-2QAC. The cable is supplied in 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.
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.
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
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.
