The Siemens 6ES7193-6AG70-0AA0 is a SIMATIC ET 200SP BA LC-LD/M12 PROFINET Bus Adapter designed to combine long-distance single-mode optical networking with an M12 Ethernet connection. The adapter provides one PROFINET interface with two switched ports: one LC-LD single-mode fiber port and one M12 port. Siemens specifies 9/125 µm single-mode fiber up to 20 km, with 10 km applicable for topology or IRT configurations and a maximum attenuation of 13 DB. The LC-LD interface operates at 1,270–1,380 nm, corresponding to 100BASE-LX. The copper side supports up to 100 m. The compact adapter measures 20 × 69.5 × 59 mm and weighs approximately 45 g. It is intended for compatible ET 200SP PROFINET devices and provides a network connection option where M12 industrial connectivity and long-distance optical fiber are required
