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)

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) is a 400Gbps direct attach copper cable for OSFP to QSFP-DD connections in 400G Ethernet data center and cloud network environments. Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs OSFP-4x100G PAM4 QDD-4x100G PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
