The 400G OSFP to 400G QSFP-DD DAC provides a 400G copper direct-attach solution with a Flat-top (OSFP-RHS) form factor, suitable for very short links and offers a cost-effective way to establish a 400-Gigabit link between 400G ports of switches/routers within racks and across adjacent racks. It is compliant with OSFP MSA, QSFP-DD MSA and IEEE 802.3bs standards.
This DAC is designed with ultra-low loss materials, square rings, twisted pair cable 8 wires and shell extension construction for superior mechanical properties and bending performance. It supports 8x50G PAM4 modulation on both ends, and is primarily used to connect a 400G QSFP-DD switch to OSFP-based 400G network adapter cards. It is tested in actual switching systems to ensure optimal signal integrity and the best end-to-end performance, ideal for SDN, ML, and Cloud Computing.
