ABSTRACT:
An optical multiplexer device is dedicated to inserting/dropping optical resources for an optical transmission line comprising an upstream fiber and a downstream fiber. The device comprises: first and second OMADs each having a first primary inlet/out1et connected to the upstream or downstream fiber, and to L internal demultiplexing channels connected to L first secondary inlets/outlets, and a second primary inlet/outlet connected to M internal multiplexing connected to M second secondary inlets/outlets, connected to M send or receive modules L external coupling channels interconnecting the L first secondary inlets/outlets, and each fitted with a respective VOA capable of placing itself in a through or blocking state for allowing or preventing an optical resource to be transferred between OMADs; and an external drop or insert channel connected to the upstream or downstream fiber, respectively, and to the first primary or second primary inlet/outlet of the second or first OMAD, respectively.
