NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 4x 200G QSFP112 2x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 4x 200G QSFP112 2x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable, 2m is a passive breakout dac direct attach copper cable with OSFP (IHS/Finned Top) to 4x QSFP112, supporting 800Gbps links over a length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for InfiniBand NDR fabrics, GPU clusters and AI training networks, and complies with OSFP MSA, QSFP112 MSA, IEEE 802.3ck, CMIS v5.0.

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 4x 200G QSFP112 2x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable, 2m is an 800Gbps direct attach copper cable for OSFP (IHS/Finned Top) to 4x QSFP112 connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is provided in 4 standard lengths from 0.5m (2ft) to 2m (7ft). One port becomes 4x QSFP112, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MCP7Y40-N002 directly. The link runs OSFP-8x 100G-PAM4 QSFP112-2x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, QSFP112 MSA, IEEE 802.3ck, CMIS v5.0. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCP7Y40-N002 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.

This assembly is listed under part number OSFP-800G-4QPC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Custom lengths beyond the standard range are available on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.
