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 provides a 400Gbps copper connection between OSFP (IHS/Finned Top) to 4x QSFP56 ports with a cable length of customized length. As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

Product Highlights

• OSFP (IHS/Finned Top) to 4x QSFP56
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Operating temperature: 0 to 70°C (32 to 158°F)

The 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 Passive Copper Breakout DAC Cable is a 400Gbps direct attach copper cable for OSFP (IHS/Finned Top) to 4x QSFP56 connections in 400G Ethernet data center and cloud network environments. The breakout design lets one high speed port feed 4x QSFP56, which raises port utilization and simplifies cabling in dense rows. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 8x 50G-PAM4 to Quad 2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

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.

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

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

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.
