400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m

The 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m is a passive dac direct attach copper cable with OSFP (RHS/Flat Top) to QSFP-DD, supporting 400Gbps links over a length of 3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0.

Applications
The 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m connects OSFP (RHS/Flat Top) to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is made in 5 standard lengths from 0.5m (2ft) to 3m (10ft). 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 OSFP-8x 50G-PAM4 QSFP-DD-8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0. 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
The part number for this assembly is OFL-400G-QDD8XPPC. We offer this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Other lengths can be custom manufactured on request. Wire gauge: 28AWG. Volume pricing is available for project quantities.
How We Pack
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.
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.
Shipping and Lead Time
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.
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.
