Cisco Compatible DAC 1m (3ft) Twin-port 800Gb/s OSFP Finned Top to 4x200Gb/s OSFP Flat Top Passive Copper Splitter Cable
NADDOD O4O112-800G-CU1 is an 800Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) to 4x200Gb/s OSFP passive Direct Attach Copper (DAC) dual breakout (aka splitter) cable for 400Gb/s End-to-End solutions. DAC cables are the lowest-cost, lowest-latency, near zero power consuming, high-speed links available due to their simplicity of design and minimal components.Main use is linking an 800Gb/s Spectrum-4 switch to OSFP-based 200Gb/s ConnectX-7 PCIe network adapter cards and BlueField-3 DPUs. NADDOD’s cable solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.
800G Breakout DAC integrates different heat sink designs of the two-end transceivers, unleashing powerful performance.
The 800G OSFP end transceiver adopts a finned top to provide the necessary thermal management when handling massive data, which is applied for Spectrum-4 Ethernet switches.
Each module on the two or four 400G OSFP breakout side has a flat-top design used in CX7 NICs and relies on heatsinks on the NIC ports to assist the module in cooling.
