400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable

For short reach 400Gbps links in 400G Ethernet data center and cloud network environments, the 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable offers a factory terminated passive twinax assembly with OSFP (IHS/Finned Top) to 4x QSFP56 connectors and a length of customized length. As a passive cable it draws essentially no power and adds no latency to the link. The cable meets OSFP MSA, IEEE 802.3cd, CMIS v4.0.

Product Highlights

• OSFP (IHS/Finned Top) to 4x QSFP56
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Operating temperature: 0 to 70°C (32 to 158°F)

The 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable connects OSFP (IHS/Finned Top) to 4x QSFP56 ports at 400Gbps in 400G Ethernet data center and cloud network environments. 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 8x 50G-PAM4 to Quad 2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

This product is designed and tested to comply with OSFP MSA, IEEE 802.3cd, CMIS v4.0. It plugs into any standards-based OSFP (IHS/Finned Top) to 4x QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at standard length under part number OSFP-400G-4QPCxxx. Other lengths of the same assembly can be produced on request. Samples for testing can be arranged before bulk orders.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
