400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx)

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) is a passive twinax direct attach copper cable with OSFP to QSFP-DD, supporting 400Gbps links over a length of customized length. 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.

Product Highlights

• OSFP to QSFP-DD
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Operating temperature: 0 to 70°C (32 to 158°F)

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) connects OSFP to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. 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. The link runs OSFP-4x100G PAM4 QDD-4x100G PAM4 modulation, which keeps it aligned with current 400G switch silicon.

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 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 is supplied at standard length under part number OSFPFL-400G-QDDPCxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.

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.

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.
