The 800G Twin-port OSFP to 4x200G QSFP112 Active Copper Splitter Cable (O4Q112-800G-ACCH) is an advanced quad breakout (splitter) solution designed for high-density InfiniBand NDR and 800G Ethernet AI supercomputing architectures. Operating eight parallel 100G-PAM4 copper channels, this cable splits a single 800G (2x400G) switch port into four independent 200G links. Equipped with built-in active signal equalizer ICs, it extends reliable copper transmission reach up to 5 meters while maintaining ultra-low latency and minimal power consumption.

Engineered for hybrid cooling topologies, the switch-side Twin-port OSFP connector features a Finned Top (IHS) design for enhanced airflow inside air-cooled switch cages. The host-side 4x QSFP112 connectors feature a Flat Top shell designed to work seamlessly with riding heat sinks inside server adapter cages. This cable is natively optimized for linking 800G NDR switches—such as NVIDIA Quantum-2 (QM9700 / QM9790) and NVIDIA Q3200-RA—directly to 200G host ports on NVIDIA ConnectX-7 HCAs and BlueField-3 DPUs/SuperNICs.

Key Features

• 800G to 4x200G Quad Breakout: Splits an 800G (2x400G) Twin-port OSFP switch port into four individual 200G (2x100G PAM4) QSFP112 adapter connections.
• Active Equalization ICs: Built-in pre-emphasis signal booster ICs extend passive copper distance limits up to 5 meters with low bit error rates (BER).
• Optimized Hybrid Thermal Profile: Finned Top OSFP end for air-cooled switch cages paired with Flat Top QSFP112 ends for server NIC riding heat sinks.
• Flexible Reach Configurations: Available in 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft), and 5m (16ft) lengths using 26AWG–30AWG wire gauges.
• Low Power Consumption: Consumes <1.5W on the OSFP switch end and <0.4W per QSFP112 host end, delivering high energy efficiency compared to optical solutions.
• 100% InfiniBand NDR Compliance: Thoroughly verified for seamless interoperability with NVIDIA Quantum-2 switches, ConnectX-7, BlueField-3 DPUs, IBTA BER standards, and CMIS protocols.
