OVERVIEW
External multiplexer modules (EMM) extend number and type of ports interconnected compatible IDU. These modules are designed to be mounted together with IDU into 19″ rack case. Up to four EMM modules can be connected in cascade. It opens extremely high flexibility for hybrid system build up. All modules support cross connect and add-drop functionality.
