NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable

For short reach 850Gbps (8x 106.25Gbps) links in InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable offers a factory terminated active dac (acc) assembly with OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) connectors and a length of 5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. The cable meets CMIS 5.0, IEEE 802.3ck, OSFP Rev5.0.

The NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable connects OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports at 850Gbps (8x 106.25Gbps) in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is available in 5 standard lengths from 1m (3ft) to 5m (16ft). 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 MCA4J80-N005. The link runs 8x100G-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 MCA4J80-N005 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers CMIS 5.0, IEEE 802.3ck, OSFP Rev5.0.

The standard part number of this assembly is OSFP-800G-AC. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG.

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.

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.

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.
