400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable
The 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable is a passive twinax direct attach copper cable with OSFP (IHS/Finned Top) to 4x QSFP56, 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 OSFP MSA, IEEE 802.3cd, CMIS v4.0.

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. By fanning one port out to 4x QSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. 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
Standards compliance covers OSFP MSA, IEEE 802.3cd, CMIS v4.0. The unit works in any equipment with a standard OSFP (IHS/Finned Top) to 4x QSFP56 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
This model is supplied at standard length under part number OSFP-400G-4QPCxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
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.
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.
Packing Details
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
