NEC G3725M Pasolink Telecom System Card / Module

The NEC G3725M is a modem unit (MD UNIT) module used within the indoor unit (IDU) of NEC’s Pasolink point-to-point microwave radio system. The MD Unit handles the modulation and demodulation of the digital signal passed between the tributary interfaces and the outdoor radio unit (ODU), forming one of the core modular cards within a Pasolink IDU chassis alongside switching and power supply modules. This card-based design lets individual functions be serviced or replaced independently, which has helped keep many legacy Pasolink links running well beyond their original deployment life. NEC’s Pasolink family remains one of the most widely installed point-to-point microwave platforms globally, particularly in mobile operator backhaul and private enterprise networks. Tech-Star (UK-based, shipped worldwide) supplies tested surplus NEC Pasolink IDU cards, including modem units, for maintenance, repair, and spares holding.
