400G OSFP PCxxx Passive DAC Flat Top
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
In 400G Ethernet data center and cloud network environments, the 400G OSFP PCxxx Passive DAC Flat Top provides a factory terminated 400Gbps link between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) ports. 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 4x 100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OSFP MSA, CMIS Rev4.0, IEEE 802.3cd. 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.
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. Volume pricing is available for project quantities.
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.
Package
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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
