Omu is a passive optical device

The Optical Master Unit (OMU) is used to supply fiber optic-powered RF amplifiers. The OMU converts the RF signals into optical signals. The OMU utilises one or several RF over Fibre (RFoF) modules to convert the RF signals from a donor radio site into optical carriers and vice versa so that the donor signals can be transported via optical fibre. The OMU II is used to convert signals from RF to light when fibre-fed repeaters are used at the remote end of the optical link. The OMU converts the RF signals into optical.
