400G OSFP Flat Top Passive DAC Twinax Cable – (OSFP to OSFP)
The 400G OSFP Flat Top (OSFP-RHS) Passive Direct Attach Copper (DAC) Twinax cable delivers reliable 400G Ethernet connectivity for ultra-short data center links. Designed for OSFP Flat Top ports, it enables cost-effective, high-bandwidth interconnections between 400G OSFP switch or router ports within the same rack or across adjacent racks.
This passive copper DAC is engineered with ultra-low-loss materials and features an 8-wire twisted pair construction with square-ring contacts and reinforced shell extension design. The result is superior mechanical durability, optimized bend performance, and stable high-speed signal transmission. Each cable is validated in live switching environments to ensure consistent signal integrity and dependable end-to-end performance.
