The bidirectional optical isolator circuit shown in the figure provides electrical isolation between two ports P1 and P2 while allowing log ic signals to be transmitted in either direction. The circuit is intended for use in a half duplex transmission line. Both ports P1 and P2 provide a matched termination and are normally positive in the quiescent state.
