an embedded PCIe Switch

The "active" term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 1-5 meters

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

powered by the Quantum-3 ASIC，leverages 200Gb/s-per-lane serializer/deserializer (SerDes) technology

The Type B polarity and low-smoke zero-halogen (LSZH) jacket make it a safe and reliable choice for professional networking infrastructures
