400G Active Optical Cable (AOC) QSFP112 to QSFP112 OM3 Cable

SVNK 400G QSFP112 Active Optical Cable (AOC) – SR8, MMF

The SVNK 400G QSFP112 Active Optical Cable (AOC) is a high-performance parallel optical interconnect engineered for 400 Gigabit Ethernet and next-generation data center networks. It supports the transmission of 8 × 50G PAM4 lanes over multimode fiber, delivering an aggregate bandwidth of up to 400 Gb/s (425 Gb/s line rate).

Built on advanced VCSEL-based optical technology, this AOC operates at a nominal wavelength of 850 nm and enables reliable short-reach connectivity of up to 70 m over OM3 and 100 m over OM4/OM5 multimode fiber. Compared with copper interconnects, SVNK 400G QSFP112 AOCs offer longer reach, EMI immunity, lighter weight, improved airflow, and simplified cable management, making them ideal for dense 400G switching architectures.

The cable integrates factory-terminated QSFP112 modules on both ends, each supporting eight high-speed PAM4 electrical lanes at 53.125 Gb/s per channel. Integrated active electronics and DSP retiming ensure excellent signal integrity, ultra-low bit error rates, and stable performance in hyperscale and HPC environments.

Fully compliant with QSFP112 MSA, CMIS 4.0, IEEE 802.3cd, and OIF-CEI-04.0, the SVNK 400G QSFP112 AOC guarantees broad interoperability with next-generation 400G switches and routers.
