First introduced in the 1970s, optical fiber-based systems have offered greater information carrying capacity; faster data transfer rates over longer transmission distances; improved voice, data, and video transmission capabilities; immunity to electrical interference; and proven long-term reliability when compared to traditional copper-only systems.

Since the late 1980s, they have also been used in an increasing number of sensor applications that monitor and measure large amounts of data and parameters such as temperature, pressure, sound, vibration, and strain along the entire length of fiber optic cables.

These optical fiber sensing solutions are designed to give operators prescriptive and predictive analytics in real-time that can help them make well-informed decisions, proactively manage systems, and detect and mitigate potential threats in real-time. In some application the cable may be designed as mainly for telecom applications providing an additional sensing capabilities In other cases the cable may be designed exclusively for sensing applications

Where are sensing technology and solutions used?

Sensing technology and solutions are used in a wide range of industries and applications, including:

• In-well and down-well monitoring in the Oil & Gas industry
• Onshore oil and gas pipeline leakage detection and prevention
• Water pipeline leakage detection and prevention
• Fluid detection for environments where moisture can cause damage
• Long-range and critical infrastructures
• Subsea systems
• Border and perimeter security
• Asset protection applications (utilities, transportation, banking facilities, government facilities, and national archives)

Unique factors to consider when designing fiber optic cables for sensing applications

Some unique factors should be considered when designing and selecting fiber optic cables for sensing applications. For example:

•In telecommunications applications that do not integrate sensing technology, the amount of signal attenuation and degree of signal distortion is usually only critical at the end of the cable run.. This is not the case in sensor applications, where the stability of the midstream optical signal across the full length of the cable is a significant factor in supporting effective system performance.

•The installation and operating conditions in sensing environments may be extreme. This means that optical fibers used in these applications may be exposed to more extreme temperatures, higher pressures, and harsh chemicals. These factors need to be addressed when designing the cable structures in these applications.
