QSFP112 400G to 2×QSFP112 200G Active Optical Cable OM4 Cable

SVNK Infibend DSP-Enabled 400G Active Optical Cable (QSFP112 to 2×200G Breakout AOC)

The SVNK Infibend DSP-Enabled 400G Active Optical Cable (Breakout 2×200G – QSFP112) is a high-performance optical interconnect solution engineered for next-generation data centers, AI clusters, and high-performance computing (HPC) environments. Designed to support 400G to 2×200G breakout connectivity, this AOC delivers stable, low-latency, and power-efficient transmission over OM4 multimode fiber up to 50 meters.

Both ends of the cable utilize the QSFP112 form factor, ensuring seamless mechanical and electrical compatibility with the latest 400G and 200G network platforms. This architecture enables direct interconnection between 400G switches and dual 200G endpoints, making it ideal for high-density spine-leaf networks, GPU fabrics, and scalable cloud infrastructures.

The transmission system is based on 850 nm VCSEL optical technology with integrated electrical drivers, while the receiving side incorporates high-sensitivity PIN photodetectors with TIA, delivering excellent optical efficiency, low noise, and long-term signal stability.

An advanced onboard DSP engine enables PAM4 retiming, adaptive channel equalization, and jitter correction, supporting up to 30 dB of host-side electrical lane loss. This ensures exceptional signal integrity even in ultra-dense systems with long electrical traces and high insertion loss.

Fully compliant with QSFP112 MSA, InfiniBand HDR/HDR100, CMIS, and IEEE high-speed electrical standards, the SVNK Infibend 400G breakout AOC provides a future-ready and interoperable solution for data centers transitioning toward 400G/200G network architectures.
