GHZ BROADBAND OPTICAL LINK (RF OVER FIBRE)
Take advantage of fibre-optic systems, designed for high-quality transmissions, even over long distance or in harsh electromagnetic environments
Unsurpassed immunity to electromagnetic fields
> 40 hours autonomy on batteries (standby >10 days)
Battery powered point-to-point modules, or up to 10 slot chassis with plugin modules
Remotely selectable transmission gain
Optical fiber cable provides total galvanic isolation
We design fiber-optic transmission systems to ensure high-quality transmissions of analog signals from 80 Hz up to 3.5 GHz over long distances or in harsh electromagnetic environments.
The compact, highly shielded electro-optical conversion module is particularly well suited to measurements in high-power electromagnetic testing applications.
In the point-to-point version, both the optical transmitter and receiver modules are battery-powered. In the point-to-frame version, the plug-in receiver modules are inserted in a 1- or 10-slot frame and are powered from the frame. Different models of MOL can be mixed in the same chassis.
The MOL3000 has a fix transmission gain of 0 dB, while the MOL2000T has a remotely selectable transmission gain from -62 dB to +24 dB.

FAQ
An RF over Fiber (RFoF) broadband optical link converts an analog RF signal into an optical signal, transmits it through a fiber optic cable, then converts it back into an electrical RF signal. Montena’s GHz broadband optical links are part of the Modular Optical Link (MOL) family, designed for reliable signal transmission in demanding electromagnetic environments.
Compared with traditional coaxial cables, RF over Fiber provides complete galvanic isolation between the measurement point and acquisition equipment, very low optical attenuation over long distances, high immunity to electromagnetic interference (EMI), and no ground loop issues in sensitive setups. The transmitter and receiver modules are battery-powered, providing more than 40 hours of autonomy.
Montena’s GHz broadband optical link supports a wide frequency range, typically from 80 Hz up to 3.5 GHz. Models such as the MOL2000T and MOL3000 are optimised for stable broadband signal transmission across this range.
Montena’s broadband optical links offer flexible deployment: standalone point-to-point configurations with a transmitter and receiver connected through an optical fiber, or modular chassis configurations where multiple receiver modules can be integrated into a dedicated frame.
The GHz Broadband Optical Link (RF over Fiber) supports frequencies from 80 Hz up to 3.5 GHz for RF measurements and fast signal monitoring (MOL2000T2, MOL3000). The MHz Broadband Optical Link – Isolated Probe is optimised for precision electrical measurements from DC up to tens or hundreds of MHz, suited for voltage measurements in high-voltage or floating potential environments (MOL500T, MOL25T).
