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.

Designed for 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 carries 400Gbps between OSFP (RHS/Flat Top) to QSFP-DD interfaces. This unit is provided in 4 standard lengths from 0.5m (2ft) to 2m (7ft). 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.

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 assembly is listed under part number OSFPFL-400G-QDDPC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Custom lengths beyond the standard range are available on request. Wire gauge: 28AWG.

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.

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.

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.

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.
