Fibre-optic links

Montena manufactures a range of broadband fibre-optic links for analogue signal transmission/ measurements from DC up to 3.5 GHz. All models enable operation in harsh electromagnetic environments and over long distance.

The MOL series is available in version point-to-point and multilink with up to 10 receivers per chassis. In the point-to-point versions, both the transmitter and the receiver modules are battery-powered and are shielded against strong electromagnetic fields. In the multilink versions the plug-in receivers have no battery, they are powered and controlled directly thru the chassis. Different models of MOL can be mixed in one chassis.

MOL25T

Analog front-end over fibre for oscilloscope, specially designed for:

• Remote measurements in harsh environments (high voltage, electromagnetic, contaminated atmosphere ..etc) or hardly accessible areas
• Monitoring of signals of EUT's during EMC tests, measurement of fast transients on high-voltage floating potentials ..etc.
• DC - 25 MHz, 2 × 1 MΩ BNC inputs, expandable to 20 channels per chassis

MOL500T  

• High impedance measurements with high bandwidth (DC - 500 MHz)
• Remote measurements in harsh environments (high voltage, electromagnetic, contaminated atmosphere ..etc) or hardly accessible areas
• Measurement of fast transients on high-voltage floating potentials
• Measurements on fast-power semiconductors (SiC, GaN, …)

MOL2000T

• Ultra-wide 80 Hz – 3.5 GHz bandwidth ensures an accurate transmission of fast-risetime and long pulse duration signals
• >40 hours autonomy on batteries (standby >10 days) 
• Remote controlled features (gain, standby) for higher flexibility
• High immunity to electromagnetic fields.

MOL3000

• Simple operation (no configurable settings), 0 dB gain
• 80 Hz – 3.5 GHz, high immunity to electromagnetic fields.
