Montena MOL500T optical link is designed for real-time measurement of electric signals from DC up to 500 MHz in a harsh electromagnetic environment.
The shielded optical transmitter has a 1 MΩ / 50 Ω BNC input, which enables connecting any sensing device (current probe, HV probe, or specific means for HF measurements). It also makes an ideal oscilloscope front-end for the remote measurement of floating potentials in industrial applications and ensures the operator’s total galvanic insulation for safe operation in high-voltage areas.
The input electric signal is conditioned, converted into an optical signal in the transmitter module, and sent to the receiver module through a single-mode fiber. The receiver module converts the optical signal back 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.
The battery-powered optical transmitter comprises a remote-controlled attenuator stage (1:1 / 10:1 / 100:1) to adjust the received signal level for optimal use of the dynamic range. The transmitter can also be remotely put in a low-power standby mode to save battery power when not used. An LED indicator shows the operating state.
A Windows-based software application remotely controls Configurable settings.

Test and Measurement Applications Include:
Surveillance of EUT during tests
Our fiber-optic transmission links are designed to transport signals in harsh electromagnetic environments in a very reliable way.
The compactness of the modules makes it an ideal solution for non-invasive measurements.
These transmission systems are essential for proper measurements during EMC or high-voltage tests.
Safe measurements in high voltage systems, in the power distribution network, or in power substations
The optical transmitter module is connected using optical fiber cable only, providing total galvanic isolation between the measurement point and the operator.
This galvanic separation also allows the measurement of floating voltage signals.
Measurement in power electronics
New solid-state switch technology operates at up to 2-3 kV. Every developer of high-power inverters with solid-state switches must optimize the switching transitions and, therefore, needs a good measurement tool to catch and analyze the fast transients of these floating voltage signals.
General transmission of analog signals from hard-to-access areas
Thanks to its high-capacity embedded lithium battery, the user can use the MOL family to transmit analog signals to or from hard-to-access areas. When not used, the module can be put in stand-by mode for months. The user can remotely wake up the system without having to physically go to the hard-to-access location (typically deep inside a complex system, in a wind turbine, in a high-security area, or simply far away from the control room, etc.).
Key Features:
All models of MOL (MOL25T, MOL500T, MOL2000T) are available in stand-alone and multilink versions.
Built-in attenuators and preamplifiers can be remotely configured to optimize the input dynamic.
The modules automatically regulate optical losses and thermal compensation for high-accuracy measurements.
The optical signal and battery levels are monitored and status messages are reported to the user interface.
Different models of the plug-in modules can be mixed into one chassis.
Applications:
Realtime measurements in harsh environments such as high voltage substations, railway infrastructures, and physics research centers.
Measurement of fast transients on high voltage floating potentials.
Fast impulses or RF signal transmission over long distances or hardly accessible areas.
HPEM / EMP / UWB testing.
