Multipoint optical transmission system

Montena MOL2000T optical link is designed for the transmission of analogue electric signals (CW and pulses) from 80 Hz to 3.5 GHz over long distance in harsh electromagnetic environment.

The input electric signal is conditioned and converted into an analogue optical signal in the transmitter module and sent to the receiver module through a fibre optic cable. The receiver module converts back the optical signal into an electric signal. The optical signal transmission is regulated with an automatic level control that maintains precise and constant performance independently of the optical losses. A second optical fibre is used as control and supervision channel between the optical transmitter and receiver.

The battery powered optical transmitter comprises remote-controlled attenuators and preamplifiers to adjust the received signal level for an optimal use of the dynamic of the optical transmission link. The optical transmitter module can remotely be put in a low power stand-by mode to save battery power when not used. A built-in rectangular pulse

generator can be remotely activated to check the link integrity. A LED indicator shows the operating state. Configurable settings can be remote controlled by an Android app or a Windows-based software application.
