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.

Applications
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 produced 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
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.
Ordering Information
The factory part number is OSFPFL-400G-QDDPC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 28AWG.
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Logistics
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
