10-Year Forecast – Fiber Optic Sensors

According to ElectroniCast, the combined use of Distributed and Point fiber optics sensors are forecast to reach $5.98 Billion in 2026…

ElectroniCast Consultants, a leading market/technology forecast consultancy, today announced the release of their market forecast and analysis of the global consumption of Fiber Optic Sensors.

According to the study, the combined use of Distributed and Point (local) fiber optics sensors reached $3.38 Billion last year (2016), and the worldwide value is forecast to reach $5.98 Billion in 10-years (2026). Market forecast data in this study report refers to consumption (use) for a particular calendar year; therefore, this data is not cumulative data.

Both the American region and the EMEA region held similar market share in the overall (distributed- and point-types) fiber optic sensor value last year. The Europe, Middle East, Africa region (EMEA) held a very slight lead in relative market (value) share last year; however, the Asia Pacific region (APAC) is projected to take-over the leadership position during the forecast period.

The EMEA region is forecast to have a strong role in the use of distributed fiber optic systems, driven by the region’s use of systems in aviation, as well as in the

Petrochemical, Natural Resources, Energy/Utility application categories.

In terms of fiber optic point sensors, the American region is forecast to maintain the market share lead throughout the 1st-half of the forecast period (2016-2021), mostly led by the use of Fiber Optic Gyros (FOGs) in the Military/Aerospace application category. The consumption values are based on the end-user application and the end-user region.

FOGs held a 65 percent market share of the worldwide Point fiber optic sensor consumption value in 2016. “All regions, thanks mainly to increases in the use in aviation and military critical mission applications (Unmanned Aerial Vehicle/UAV and missile guidance, navigation, north finding/tracking, robotics, aviation and aeronautics and other) are forecast to show impressive increase consumption quantity (volumes) and values for the FOG systems,” said Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.

The market forecast of the Distributed Sensors is segmented by the following applications:

Manufacturing Process/Factory
Civil Engineering/Construction (buildings, bridges, tunnels, etc)
Military/Aerospace/Security
Petrochemical/Energy/Utilities/Natural Resources
Biomedical/Science

The Fiber Optic Point Sensor Forecast further segmented by the following sensing/measuring quantity (measurand) types:

Mechanical Strain
Temperature
Pressure
Chemical, Gas, Liquid
Vibration, Acoustic, Seismic
Displacement, Acceleration, Proximity
Electric, Current and Magnetic Field – Fiber Optic Sensors
Rotation (such as Fiber Optic Gyroscopes: FOGs)

“ElectroniCast counts each Point fiber optic sensor as one unit; however, the volume/quantity (number of units) of Distributed fiber optic sensors is based on a complete optical fiber line/link, which we classify as a system. Since a distributed optical fiber line (system) may have 100s of sensing elements in a continuous-line, it is important to note that we count all of those sensing elements in a distributed system as one (system) unit – only. Distributed fiber optic sensor systems involve the optic fiber with the sensors embedded with the fiber; also included is the optoelectronic transmitter/receiver, connectors, optical fiber, cable (fiber jacket) the sensor elements, and other related components,” Montgomery added.

According to ElectroniCast, the combined use of Distributed and Point fiber optics sensors reached $3.38 Billion in 2016…

Fiber Optics: How Fused Fiber Optic Couplers Work in Modern Scenario

A fiber optic coupler is a gadget utilized as a part of optical fiber systems with at least one input fibers and one or a few output fibers. Light entering an input fiber can show up at least one outputs and its power distribution potentially relying upon the wavelength and polarization. Such couplers can be fabricated in various courses, for instance by thermally fusing fibers with the goal that their cores get into intimate contact. In the event that every single involved fiber are single-mode (supporting just a solitary mode for each polarization heading for a given wavelength), there are sure physical restrictions on the performance of the coupler. Specifically, it is unrealistic to consolidate at least two contributions of the same optical frequency into one single-polarization output without significant excess misfortunes. Be that as it may, such a limitation does not happen for various information wavelengths: there are couplers that can consolidate two contributions at different wavelengths into one output without exhibiting significant misfortunes. Wavelength-sensitive couplers are utilized as multiplexers in wavelength-division multiplexing (WDM) telecom systems to join a few information stations with various wavelengths, or to isolate channels.

Fiber optic couplers (fused couplers) are intended for control part and tapping media transmission hardware, CATV systems, and test gear. This sort of little parts are accessible independently or incorporated into modules for fiber security exchanging, MUX/DMUX, optical channel checking, and include/drop multiplexing applications.

We utilize electronic couplers constantly, for example, a telephone coupler which gives you a chance to associate both a phone and a fax machine to a similar phone line. Fundamentally you can purchase these couplers from home depot or other electronic retailers.

Optical couplers have an indistinguishable usefulness from electronic couplers: they split the flag to numerous points (devices). Fiber optic couplers are required for tapping (monitoring the flag quality) or more complex telecommunication frameworks which require more than straightforward point-to-point connections, for example, ring architectures, bus architectures and star architectures.
