Amphenol Commercial OSFP Interconnect System

Amphenol Commercial OSFP Interconnect System features 60 contacts per port, with a 0.6mm contact pitch, and eight high-speed channels. The OSFP footprint is optimized for signal integrity performance and is built for use in high-speed serial applications. This Amphenol Commercial interconnect system is enhanced for low crosstalk and offers ground commoning for resonance dampening. The module side features an integrated heat sink for optimal thermal performance. The OSFP series is designed for 1U applications, including cellular infrastructure, hubs, switches, servers, and more.
