The LCN-LLG is the fiber optic LWL coupler of the LCN bus system. It is designed as a double transmitter-receiver module and has connections for the LCN two-wire bus and for the fiber optic cable. Since it does not have its own processor, parameterization using the LCN system software LCN-PRO is not necessary. The fiber optic LWL coupler LCN-LLG is used to connect spatially separated LCN buses within an LCN segment with a range of 2 km. The LCN-LLG is used to connect individual building areas so that all LCN bus modules can communicate with each other.
