400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx)

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) provides a 400Gbps copper connection between OSFP to QSFP-DD ports with a cable length of customized length. As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

Product Highlights

• OSFP to QSFP-DD
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) carries 400Gbps between OSFP to QSFP-DD interfaces. The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. 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-4x100G PAM4 QDD-4x100G PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards compliance covers IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. The unit works in any equipment with a standard OSFP to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This model is supplied at standard length under part number OSFPFL-400G-QDDPCxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.

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.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.
