ISD400-6111 is an optical data-transmission module in SICK's ISD400 family, designed to carry Ethernet-capable data between ISD400 devices over a fiber-optic link. It extends the ISD400 network across machines and production lines, with link distances specified from 0.2 m to 180 m. As a component of the ISD400 system, it enables modular, optical data transmission in industrial automation environments.
