NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G QSFP112 4x 100G PAM4 InfiniBand NDR Active Breakout DAC Cable

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G QSFP112 4x 100G PAM4 InfiniBand NDR Active Breakout DAC Cable provides an 850Gbps (8x 106.25Gbps) copper connection between OSFP (IHS/Finned Top) to 2x QSFP112 ports with a cable length of 1m (3ft). 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.

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G QSFP112 4x 100G PAM4 InfiniBand NDR Active Breakout DAC Cable is an 850Gbps (8x 106.25Gbps) active copper cable for OSFP (IHS/Finned Top) to 2x QSFP112 connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is manufactured in 5 standard lengths from 1m (3ft) to 5m (16ft). One port becomes 2x QSFP112, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCA7J65-N001. The link runs 8x100G-PAM4 to Dual 4x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: CMIS 5.0, IEEE 802.3ck, OSFP MSA Rev5.0, Q112 MSA. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCA7J65-N001 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Part number of this model: OSFP-800G-2QAC. 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: 30AWG. Volume pricing is available for project quantities.

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.

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.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
