NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top

For short reach 400Gbps links in InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top offers a factory terminated passive twinax assembly with OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets OSFP MSA, CMIS Rev4.0, IEEE 802.3cd.

Product Highlights

• OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Length: standard options (4) from 0.5m (2ft) to 2m (7ft)

Designed for InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top carries 400Gbps between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) interfaces. This unit is manufactured in 4 standard lengths from 0.5m (2ft) to 2m (7ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

Standards compliance covers OSFP MSA, CMIS Rev4.0, IEEE 802.3cd. The unit works in any equipment with a standard OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Part number of this model: OSFPFL-400G-PC. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Our factory also produces custom lengths beyond these on request. 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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

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.
