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.

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 available 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. 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.

This product is designed and tested to comply with CMIS 5.0, IEEE 802.3ck, OSFP Rev5.0. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MCA4J80-N005.

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. Samples for testing can be arranged before bulk orders.

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.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.
