An optical multiplexer device (D) is dedicated to inserting/dropping optical resources into or from an optical transmission line comprising incoming and outgoing optical fibers (F 1 , F 2 ). The device (D) comprises: i) first coupler means (C 1 ) having an inlet and an outlet connected respectively to the incoming optical fiber (F 1 ) and to the outgoing optical fiber (F 2 ), and an inlet/outlet ( 1 ) coupled to the inlet and the outlet; ii) both-way multiplexer/demultiplexer means ( 2 ) defining at least two internal channels ( 3 ) each connected to a primary inlet/outlet (ES 1 ) coupled to the inlet/outlet ( 1 ) and comprising at least two secondary inlets/outlets (ES 2 ) each connected to an internal channel ( 3 ); and iii) at least two send and/or receive modules (R, T) each coupled to a secondary inlet/outlet (ES2) by both-way light guide means ( 4 ') fitted with optical processor means ( 5, 6 ) capable, on order, of taking up at least a reflection state reflecting an optical resource to the secondary inlet/outlet (ES 2 ) that delivered it and a transmission state enabling an optical resource to be transferred between a send and/or receive module (R, T) and the associated secondary inlet/outlet (ES 2 ), the optical power that is transmitted or reflected optionally being adjustable.
