Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m carries 400Gbps between OSFP (RHS/Flat Top) to QSFP-DD interfaces. This unit is produced 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.
Standards and Compatibility
Standards compliance covers IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0. 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 OFL-400G-QDD8XPPC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
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.
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.
