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)

Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) carries 400Gbps between OSFP to QSFP-DD interfaces. 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. 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. Samples for testing can be arranged before bulk orders.

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.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.
