400G OSFP 4x 100G PAM4 Flat Top to 400G QSFP-DD 4x 100G PAM4 Passive DAC Cable

The 400G OSFP 4x 100G PAM4 Flat Top to 400G QSFP-DD 4x 100G PAM4 Passive DAC Cable, 2m is a passive twinax direct attach copper cable with OSFP (RHS/Flat Top) to QSFP-DD, supporting 400Gbps links over a length of 2m (7ft). 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 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417.

In 400G Ethernet data center and cloud network environments, the 400G OSFP 4x 100G PAM4 Flat Top to 400G QSFP-DD 4x 100G PAM4 Passive DAC Cable, 2m provides a factory terminated 400Gbps link between OSFP (RHS/Flat Top) to QSFP-DD ports. This unit is supplied in 4 standard lengths from 0.5m (2ft) to 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.

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 (RHS/Flat Top) 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 carries part number OSFPFL-400G-QDDPC. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Non-standard lengths can be produced on request. Wire gauge: 28AWG.

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.

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.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
