NVIDIA InfiniBandNVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable
The NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable provides an 850Gbps (8x 106.25Gbps) copper connection between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports with a cable length of 5m (16ft). 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.

Applications
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 manufactured in 5 standard lengths from 1m (3ft) to 5m (16ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the 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
Part number of this model: OSFP-800G-AC. Length options are 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.
Package
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.
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.
Our Testing Process
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.
