NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Breakout AOC
The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Breakout AOC connects OSFP (IHS/Finned Top) to 4x QSFP56 ports at 400Gbps over Breakout AOC fiber at 850nm. Because the optics are built into the cable ends, installation is plug and play with no separate transceivers to manage, and airflow inside the rack stays unobstructed. It is well suited to InfiniBand HDR fabrics, HPC clusters and AI computing networks. You can order standard lengths from 3m (10ft) to 30m (98ft).

Applications
The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Breakout AOC is a 400Gbps active optical cable for OSFP (IHS/Finned Top) to 4x QSFP56 connections in InfiniBand HDR fabrics, HPC clusters and AI computing networks. This unit is delivered in 6 standard lengths from 3m (10ft) to 30m (98ft). One port becomes 4x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs OSFP-8x 50G-PAM4 QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE 802.3cd, CMIS 5.0, SFF-8661, SFF-8636. The unit works in any equipment with a standard OSFP (IHS/Finned Top) to 4x QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
The ordering part number is OSFP-400G-4QAO. We make this cable in 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). Special lengths outside this range can be produced to order.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Tested Before Shipment
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.
