Cisco Compatible Passive Copper Splitter Cable, Twin Port 800Gb/s to 4x200Gb/s, OSFP Finned Top to 4xQSFP112 Flat Top, 1m
NADDOD O4Q112-800G-CU1 is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 4x200Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Flat Top passive Direct Attach Copper (DAC) quad breakout (aka splitter) cable for End-to-End Ethernet solutions. The 8-channel Twin port OSFP end uses a finned top form-factor for use in OSFP switch cages. The four 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 connector cage adapters. 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.
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 QSFP112 breakout side has a flat-top design used in CX7 NICs and DPU, Which relying on heatsinks on the NIC ports to assist the module in cooling.
