Optical Master Unit (OMU II)

Manufacturer: Cobham Wireless Warranty: 12 month(s) Stock: Available 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 II is a headend system that can be connected directly to a base station or off-air device such as a digital repeater or bi-directional amplifier. In the downlink direction, the OMU picks up the signal from the BTS, converts it into an optical signal and transfers it over a fibre optical cable to the repeater. In the uplink direction, the OMU receives the signal from the remote repeater via the fibre optical cable, converts it to a RF signal and sends it back to the base station
