In this post, we explore the evolution of photonics alignment - from early manual single-fiber setups to today's fully automated FAU (Fiber Array Unit) alignment systems. 07/15/25, 05:53 AM | Automation & IIoT, Engineering | PI USA (Physik Instrumente) | lidar, The. Discover how SmarAct's precision technology enhances fiber array assembly for optimal performance in photonic systems. supporting the growing need for compact photonic. FAU (Fiber Array Unit) multifiber assemblies offer high-density, high bandwidth solutions for the new era of fiber optic applications, including telecommunications, data centers, silicon photonics, defense and medical applications. OpTek System's proprietary laser technology offers end-to-end. PI's modular hardware and ACS EtherCAT-based controller architecture allow OEMs to construct really high performance and safe automation assemblies of arbitrary complexity. Alternatively, PI's Engineered Subsystems Group stands ready to assemble and ship custom automation subassemblies like the one. ficonTEC provides automated stand-alone and in-line micro-assembly and testing solutions for the photonics industry, and is continually and actively involved in several internationally-supported initiatives, internally driven research projects as well as case-studies. However, their adoption is currently held back by the considerable cost involved in the production of these.
