NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable
The NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable is a active dac (acc) direct attach copper cable with OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top), supporting 850Gbps (8x 106.25Gbps) links over a length of 5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for InfiniBand NDR fabrics, GPU clusters and AI training networks, and complies with CMIS 5.0, IEEE 802.3ck, OSFP Rev5.0.

Applications
Designed for InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable carries 850Gbps (8x 106.25Gbps) between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) interfaces. This unit is made 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.
Standards and Compatibility
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.
Ordering Information
The part number for this assembly is OSFP-800G-AC. We offer this cable in 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). Other lengths can be custom manufactured on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Reliability Control
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.
Packing Details
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.
