    Introduction The MO-480/481 is a broadcast grade DVB-T/T2 modulator available in a standard 1U high 19" rack case (MO-480) and also in an open frame chassis (MO-481) that can be used for MFN as well as SFN applications. The modulator has several Transport Stream and T2-MI inputs in ASI and IP formats so that it can be easily interfaced with other existing transmission equipments such as gateways.
