It involves micro-mirrors and a solenoid to direct signal out through one of N ports. Here is an example from BlackBox https://www.blackbox.com/en-us/store/product/detail/Fiber-Optic-A-B-Switch-Latching-SC-Multimode-Remote-Control-Dry-Contact/SW1043A-MM This particular version latches into the last selected position, but there are versions with many more input/output ports, and which fail to one position on power-outages. These generally use MEMS devices and get quite pricey...
