Montena MOL2000T
80 Гц - 3,5 ГГц, КУ от -62 дБ до +24 дБ
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.
Typical frequency response (at 0dB gain)
Bandwidth 80 Hz to 3.5 GHz
Bandwidth 80 Hz to 3.5 GHz
The compact optical transmitter is battery powered and especially shielded for a very high immunity to electromagnetic fields.
The compact optical receiver for point-to-point application is battery powered and especially shielded for a very high immunity to electromagnetic fields. It has one USB interface for system configuration and supervision.
The compact optical receiver for multilink application is a plugin module. To be inserted in the MOL-MF-10 chassis.
The multilink main frame is a 19", 2 HU chassis for up to ten MOL2000T-RX-M modules. The receiver modules are powered and controlled from the chassis back plane.
The system is delivered with Montena FibREmote software application, running on Windows PC.
The application allows simple configuration and monitoring of the MOL2000T optical links.
Configurations can be stored and recalled at any time in order to ease the configuration of large test setups.
A simpler version of the control software application running on Android tablet can be used for the standalone, point-to-point MOL2000T transmission link.
The MOL2000T family utilises dual fibre optic cables with FC/APC and ST connectors.
