The FibreMDU Virtual twin, connects to a single fibre and converts optical signals from any Global Invacom derived transmitter; OTX, ODU32, Fibre LNB, O2E or O2O (including some Televes and Triax OEM versions) to IF, providing two universal satellite feeds. This is done either through a network of passive optical splitters (PON) or directly from the transmitter (with attenuation).
