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 is a active breakout dac (acc) direct attach copper cable with OSFP (IHS/Finned Top) to 2x QSFP112, supporting 850Gbps (8x 106.25Gbps) links over a length of 1m (3ft). 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 MSA Rev5.0, Q112 MSA.

Designed 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 carries 850Gbps (8x 106.25Gbps) between OSFP (IHS/Finned Top) to 2x QSFP112 interfaces. This unit is delivered in 5 standard lengths from 1m (3ft) to 5m (16ft). The breakout design lets one high speed port feed 2x QSFP112, which raises port utilization and simplifies cabling in dense rows. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MCA7J65-N001 directly. The link runs 8x100G-PAM4 to Dual 4x100G-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 MSA Rev5.0, Q112 MSA. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MCA7J65-N001.

The ordering part number is OSFP-800G-2QAC. We make this cable in 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft) and 5m (16ft). Special lengths outside this range can be produced to order. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.
