About the DxS Platform

Fosina introduces the DxS solution, a modular distributed fiber optic sensing technology that can combine in a single interrogator:

  • Distributed Acoustic Sensing (DAS)
  • Distributed Strain Sensing (DSS)
  • Distributed Temperature Sensing (DTS),
  • Distributed Thermal Gradient Sensing (DTGS)

It offers the flexibility to combine the best of DAS, DSS, DTS and DTGS with unequalled performances in the market.


DAS and DSS/DTS modes automatically software selectable to acquire multiple parameters (temperature, strain, acoustic and thermal gradient) with a single interrogator


1.5 m > Spatial Resolution > 100 m​
0.5 m > Spacing > 20 m​​
Fiber Length up to 200 km​​
Ping Rate up to 100 kHz​

Edge Computing

Our DxS can independently pre-process the massive amount of data that is gathered​ and execute any post-processing required by the client. The system allows for clients and partners to use DxS processing hardware to run their own algorithms, including optional GPGPU (General-Purpose Graphics Processing Unit) support.

Integrated & customizable alarm display with SCADA data delivery​


The DxS can be mounted in customized transport case that allow the equipment to travel safely across the world against harsh environment where drop, vibrations and water can happen.

Web-based UI​

FOSINA designed its own web-based user interface to enable anyone across the world to remotely access the DxS from any web-browser with a secured, authenticated connection.​

The interrogator can send data to the operator control system via a variety of communication protocols for seamless integration with your structural integrity and predictive maintenance monitoring application.


The FOWIM technology from Fosina is the state-of-the-art WIM (Weight-In-Motion) system globally where the transducer is only sensing with optical fiber (completely passive with no electronics) and allow to collect and process axle weight from overloaded truck in real time with no impact on traffic flow. The system has been designed in such a way that can be upgraded over time if additional features such as tyre pressure is required.

Single Platform

On-board I/Os are used to communicate with the transducer which is monitoring overloaded trucks and data processed and stream to Security Center to visualize alarms via a web-based interface designed by FOSINA

The FOSINA Automatic License Plate Recognition system presents the following features:​
- On-board ALPR processing ensures high-performance, scalability, and ultra low reading latency. ​
- Varifocal lenses ease specification and design​
- Power over Ethernet Plus (PoE+) enabled to simplify deployment​
- IP67-rated enclosure allows for operation in extreme weather conditions and harsh environments​
- Read license plates​
- Dual lane feature available

Low Power

Each FOWIM sensor consists of an optical transducer along with an associated data acquisition hardware, embedded PC, 3G/LTE modem, and ALPR system. The full sensor operates on less than 100W, enabling it to be powered from harvested energy supplies.

Edge Processing​

With processing on-board, the FOWIM solution brings intelligence to the edge of the system with ultra low reading latency. Since only plate read data needs to be transferred over the network, this means decreased data load on the network and server as all the image processing and analysis is done in the unit.

ShapeCreated with Sketch.

The design of our transducer is taking into account three key elements that makes it unique:​
- Designed to maintain mechanical properties and resist over time without losing its elastic properties. ​
- Designed to have the best mechanical transfer function between the transducer and the fiber optic itself.​ ​
- Designed to allow ease of implementation and commissioning

Small Footprint​

FOWIM acquisition system is contained within a ruggedized enclosure which is easy to transport and once installed has a small footprint.​

FOSINA is partnering with an experienced company that is used to design enclosures for deploying equipment in harsh environment along highways. A customized modelling for heat dissipation is completed to fit country weather.

Fibre Optic Weight In Motion

FOWIM Web-Based Software

Individual FOWIM sensors can be deployed in a distributed network to monitor roads and detect the weight and details of vehicles passing by. Information about those vehicles, including a detection of overweight vehicles, will be centrally monitored in a secure office via a web-based application.

This web-based user interface provides full remote access including, system setup and diagnostics, data visualization and processing, and alert notification.

Web-Based Dashboard

The user-friendly dashboard shows most recent events with detailed alarm view to provide required information about infractions, including:
- Date and time of infraction
- Location
- Detected weight
- License plate
- Photograph

Centrally Managed UI

The application provide for a network of up to 150 FOWIM sensors along with a centrally managed application portal for clients to setup, monitor, and maintain the system remotely.

Photograph & number plate

The system will also capture a photograph of the vehicle and determine the vehicle registration. The number plate can then be used to query external databases (such as governmental commercial vehicle databases) for vehicle classification, thus providing further data about the vehicle in question.

Historical report generation to better understand high risk locations thanks to statistics FOSINA tool including:
- Per sensor and system wide reports
- User selectable date range
- Number of vehicles monitored
- Number of infractions detected

All communication across public networks are encrypted using TLS security protocols. All data is encrypted to the latest standards to ensure client data is protected end-to-end. User identities are managed with certificates and multi-factor authentication as well as different layers of authorization available to limit access to important parts of the system.​
