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
In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP Active DAC Cable provides a factory terminated 850Gbps (8x 106.25Gbps) link between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports. This unit is offered in 5 standard lengths from 1m (3ft) to 5m (16ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. 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
Order this assembly under part number OSFP-800G-AC. Available lengths are 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). If you need a length outside this list, our factory can build it to order. Wire gauge: 26AWG. Samples for testing can be arranged before bulk orders.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
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.
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.
