Applications
The 400G OSFP 4x 100G PAM4 Flat Top to 400G QSFP-DD 4x 100G PAM4 Passive DAC Cable, 2m is a 400Gbps direct attach copper cable for OSFP (RHS/Flat Top) to QSFP-DD connections in 400G Ethernet data center and cloud network environments. This unit is delivered 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. It plugs into any standards-based OSFP (RHS/Flat Top) to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The ordering part number is OSFPFL-400G-QDDPC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG.
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.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
Quality and Testing
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.
