Split-Mount Microwave Equipment – IDU

The IDU implements the functions including service access, service grooming, multiplexing/demultiplexing, and modulation/demodulation. Thus the IDU is the main part of a set of microwave equipment. If we consider the IF board as the line board of optical network equipment, then the IDU is very much similar to Huawei case-shaped optical transmission equipment. An IDU contains service boards (SDE, SD1, SLE, SL1, PH1, PO1), cross-connect, power and clock board (PXC), system control and communication board (SCC). This figure shows the internal functional module structure of an IDU.
