Fixed gain optical transmission link

Description
MOL3000 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 electrical signal. Both transmitter and receiver modules are shielded and are powered with embedded batteries. The optical signal transmission is regulated with an automatic level control that maintains precise and constant performance independently of the optical losses.
