400G Active Optical Cable (AOC) QSFP56-DD to QSFP56-DD OM3 Cable

SVNK 400G QSFP56-DD Active Optical Cable (AOC) – SR4, MMF

The SVNK 400G QSFP56-DD Active Optical Cable (AOC) is a high-performance parallel optical interconnect engineered for 400 Gigabit Ethernet, cloud, and hyperscale data center environments. It supports the transmission of 4 × 100G PAM4 optical channels 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, the 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 QSFP56-DD AOCs provide 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 QSFP56-DD modules on both ends, each supporting high-speed 100G PAM4 channels with built-in active electronics and DSP retiming to ensure excellent signal integrity, ultra-low bit-error rates, and stable performance in hyperscale and HPC deployments.

Fully compliant with QSFP56-DD / QSFP-DD MSA, CMIS 4.0, IEEE 802.3cd, and OIF-CEI-04.0, the SVNK 400G QSFP56-DD AOC guarantees broad interoperability with next-generation 400G switches and routers.
