The 400G OSFP PCxxx Passive DAC Flat Top provides a 400Gbps copper connection between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) ports with a cable length of 0.5m (2ft)~2m (7ft). 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.

Applications
The 400G OSFP PCxxx Passive DAC Flat Top connects OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied at 0.5m (2ft)~2m (7ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 4x 100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
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.
Ordering Information
This model is supplied at 0.5m (2ft)~2m (7ft) under part number OSFPFL-400G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG.
Factory Custom Capability
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Our Testing Process
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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
