Applications

Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable carries 400Gbps between OSFP (IHS/Finned Top) to 4x QSFP56 interfaces. The breakout design lets one high speed port feed 4x QSFP56, which raises port utilization and simplifies cabling in dense rows. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 50G-PAM4 to Quad 2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards and Compatibility

Compliance: OSFP MSA, IEEE 802.3cd, CMIS v4.0. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Ordering Information

This model is supplied at standard length under part number OSFP-400G-4QPCxxx. Other lengths of the same assembly can be produced on request.

Our Testing Process

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Package

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.

Worldwide Delivery

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
