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

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

The SVNK 400G OSFP Active Optical Cable (AOC) is a high-performance parallel optical interconnect designed 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 passive copper solutions, SVNK 400G OSFP AOCs provide longer reach, lower weight, superior EMI immunity, improved airflow, and simplified cable management, making them ideal for dense, high-speed environments.

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

Fully compliant with OSFP MSA, CMIS 4.0, IEEE 802.3cd, and OIF-CEI-04.0, SVNK 400G OSFP AOCs are engineered for seamless interoperability with leading 400G switch and routing platforms.
