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…

About Fiber Optic Components

Fiber optic components are an integral part of the fiber optic infrastructure that is deployed across countries as well as continents to meet the increasing demand for the fiber optic communication. The global fiber optic communication market majorly consists of two segments that are fiber optic cables and fiber optic components.

Fiber optic cables use light as the carrier to transfer information between two places. They are used in fiber optic communication wherein they transmit these signals at long distances. They support higher bandwidth as compared to copper cables, which makes them a preferred choice for next-generation communication technologies such as 4G and 5G. Optical signals can resist electromagnetic interference. This results in a lower attenuation of the signal, and it becomes less prone to noise.

The analysts forecast the global fiber optic components market to grow at a CAGR of 10.37% during the period 2017-2021.

Commenting on the report, an analyst from the research team said: “The latest trend gaining momentum in the market is increasing long-haul and ultralong-haul networks. Long-haul optic networks are used for the transmission of information over optic fiber cables for long distances. Long-haul optics are used to connect countries and cities across the globe. Most of these networks range from hundreds to thousands of kilometers. They have mostly migrated to 10 Gbps-based DWDM systems with 32 channels or more.”

According to the report, one of the major drivers for this market is Increasing migration from copper to optic fiber. The major driver for the growth of the fiber optic components market is the migration from copper cabling to optic fiber. Copper fiber uses electrical impulses to send information across long distances. This leads to large attenuations and distortion of data. Copper wires can easily be tapped, which can lead to security issues and challenges. Optic fibers are inexpensive, lightweight, and non-flammable, and can carry higher bandwidths than copper wires.

Further, the report states that one of the major factors hindering the growth of this market is High price of components and their installation. Fiber optic components are priced much higher than their copper counterparts. For instance, the price of a desktop computer network interface card for 10 or 100 Mbps Ethernet on Cat 5 ranges between $60 and $80. Whereas, the price of a fiber network interface card is $100-$400. The cost of fibers varies widely as they have numerous cable and connector styles. Each connector is priced from $1 to $15. The installation cost of a fiber optic line can go up to $30,000 for an entire building. If an ISP chooses to opt for an optic fiber connection, they would need to dig out the entire copper installation wiring and replace it with optical fibers. GoogleFiber, a provider of fiber to the premises, estimated that the cost of wiring a fiber network into a major American city would cost approximately $1 billion. This is an extremely expensive process as ISPs opt for upgrades rather than dig up the entire line.

The CWDM are by and large in view of thin coat channel innovation which is the type of item fall under the WDM class. There arrived in a total scope of Class-8 CWDM Mux-Demux and also OADM that stands for Optical Add Drop Multiplexer units with a specific end goal to meet a wide range of necessities and system arrangements.

Likewise, it has across the board applications that require the Channel CWDM. Some of them include: Gigabit and 10G Ethernet, Fiber Channel, ATM, ESCON, in Metro total, SDH/SONET, and CATV and so forth. Presently, we should talk about the accompanying components and utilizations of Channel CWDM that settle on it an ideal decision for all. The CWDM Mux / Demux items give up to 16-channel or even 18-channel Multiplexing on a solitary fiber. Standard CWDM Mux/Demux bundle sort include: ABS box bundle, LGX pakcage and 19″ 1U rackmount.


  • The loss of insertion quality creates from the presentation of a gadget into the optical fiber is by and large lesser in CWDM than alternate gadgets; this produces short inclusion costs.
  • Channel-8 CWDM is dependably very steady and solid in the meantime. Not at all like every other sort of WDM class, the Channel CWDM has higher dependability.
  • The CWDM items are typically Epoxy free on optical way; this prompts better working and Epoxy free condition while the execution.
  • In CWDM, the channel segregation is very high. This expanded seclusion prompts better and successful outcomes.


WDM and Access Organize: As these channel sorts are the piece of WDM class, these have their best application in the WDM and also Access systems.

Line Observing: These items have their incredible use in line checking. This guarantees there is no crash on a similar line of some other range or frequency.

Cellular Application: The CWDM channel arrangements have their utilizations and applications additionally in the Cellular area, and advances as the unequaled panacea for some different parts and ventures.

Telecommunication: The broadcast communications devours Channel-8 CWDM at an incredible rate. It needs to utilize these items for the straightforward transmission of signs and utilization of the filaments for the same.

Aside from every one of the elements and applications, the capacity of CWDM is additionally to unravel the deficiency of fiber and straightforward transmission of exchange while lessening the charges of system building. This is the motivation behind why the Channel CWDM and LGX CWDM Mux and DeMux Module have a matter of extraordinary heights in the realm of fiber optics, flag transmission and multiplexing and so forth.

In today’s high tech world, there is a desperate need for bandwidth. The development of WDM (wavelength division multiplexing) technology has greatly helped us to expand the network capacity over a single fiber. A fiber optic coupler is a device used in fiber optic systems with input fibers (single or more) and output fibers (single or more). It is different from WDM devices.

The main benefits of Optical fused couplers are as follows:-

Combining: This Fiber Optic Couplers combine two signals and yield single output.
Splitting: The Splitters supply two outputs by using the single optical signal.
On the other hand, WDM multiplexer and demultiplexer divide the different wavelength fiber light into different channels. WDM is further divided into CWDM (coarse wavelength division multiplexing) and DWDM (dense wavelength division multiplexing). Generally, the WDM systems operate on 9µm single-mode fiber optical cables although it is not necessary.

If we specifically talk about the CWDM method, CWDM multiplexes multiple optical carrier signals on a single optical fiber. It uses different wavelengths/colors of laser light combined in a MUX in order to carry different signals. Mux/DeMux is one of the most important components of CWDM systems.

The LGX CWDM Mux and DeMux module comes with a 8 Channel (dual fiber) with 1U 19 Rack Mount Box that utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It has been designed to provide optical networking support over a grid of CWDM optical wavelengths in high-speed Fibre Channel and Ethernet communication for metropolitan area networks (MAN).

The optical component is easy to operate with a reliable low-maintenance design. The MUX is passive and it does not use power supplies or electronics. It is capable of multiplexing and demultiplexing ITU-T G.694.2 wavelengths up to 8 channels in increments of 20nm from 1270 nm to 1610 nm. “ITU” specifies the exact center of 8CH CWDM Mux and Demux dual fiber 1U 19 Rack Mount Box wavelength such as 1531nm, 1591nm, 1611nm, etc.

The 8 Channel CWDM Mux and Demux dual fiber 1U 19 Rack Mount Box are protocol and rate transparent. They allow different services up to 10Gbps transported across the same fiber link. It works seamlessly with transceivers to optimize the link length, signal integrity, and overall network cost. It can be incorporated into a single rack-mount solution for a better design, power, and space efficiency.

As per the working principle, MUX and DEMUX can be used in various fields, such as communication systems, computer memories, telephone networks, etc. It is a cost saving method of connecting a multiplexer and a demultiplexer together over a single channel.

In fiber-optic world of communication, wavelength-division multiplexing or WDM is an innovation which multiplexes various optical transporter signals onto a solitary optical fiber by utilizing distinctive wavelengths, that is the shades of the laser light. This system empowers bidirectional interchanges in more than one strand of fiber, and also increases the limits and domains of it. The term wavelength-division multiplexing is generally connected to an optical transporter, which is normally depicted by its wavelength, though recurrence division multiplexing is commonly applied to a radio bearer which is all the more of a frequently portrayer by recurrence. This is a simple convention since wavelength and recurrence convey a similar data.

How a WDM system works:

A WDM framework utilizes a multiplexer at the transmitter to combine the few signs and a demultiplexer at the collector to part them separated. Hence, WDM Mux and DeMux Modules are made to be used with the correct kind of fiber as it is conceivable to have a gadget that does both all the while, and can work as an optical add-drop multiplexer. The optical filtering gadgets utilized have ordinarily been etalons or to say, stable solid-state single-frequency Fabry–Pérot interferometers in the form of a thin-film-covered optical glass.

Need of WDM Multiplexing:

Since the physical fiber optic cabling is costly to actualize for every single company independently, its ability development by utilizing a Wave Division Multiplexing (WDM) is the need of the hour. WDM innovation was created to extend limits of single fiber systems can give. A WDM framework utilizes a Multiplexer at the transmitter to join a few wavelengths together; thus each one conveys diverse flag and signals via a demultiplexer at the recipient to make them separated. Both Mux and Demux are latent parts of the circuit, as their requirement of power is nil.

Types of WDM available:

These days there are a few sorts of institutionalized WDM in availibility:

Polarizing Beam combiners / splitters are the devices used to combine two polarized light signals or split single non-polarized light into two polarized parts. These combiners and splitters are designed and developed to split light beams by deploying the polarization state and not by wavelength or intensity.

The polarizing beam splitters / combiners typically have 0° or 45° angle of incidence and a 90° division between the beams; this generally depends on the configuration. There are two types of Polarization beam combiners and splitters; these are described below:

  1. Incoherent Polarization Combining / Splitting

The Incoherent combining or splitting is the simpler variant and the basic technique. In this method, the resulted beams of two broad area laser diodes are sent onto a thin-film polarizer so as to reflect one of the beams while transmit the other; both of these beams then propagate in the same direction. As a result, one attains an unpolarized beam (with the combined optical power of the input beams) and the same beam quality. Consequently, the brightness gets nearly doubled.

This technique is often used for any-a-applications, for instance, end-pumping of a solid state laser with an increased power. However, the technique is not suitable for power scaling.

  1. Coherent Polarization Combining / Splitting

With coherent beam combining or splitting it is viable to attain a linear polarized state in the output, if two mutually coherent beams are combined. If two ports have the equal input powers, the output polarization would be typically rotated by 45° -depending on the polarization direction of any of the input beams.

Also, the coherent polarization combining can be repeated several times because of the linear output polarization. Thereby, this technique is suitable for power scaling.

A polarization beam combiner and splitter is often used in photonics instrumentation, optics and semiconductors to transmit p-polarized light while reflecting s-polarized light. These hold a world of worth when it comes to optics, telecommunication and fiber applications, and make the working effective as well as effortless.

The cladding power stripper also referred to as the multimode optical power stripper is designed for amplifier applications and high power fiber laser. It is an ideal device  for ASE, residual pump power stripping, core modes that have escaped from double cladding fibers inner cladding while ensuring preservation of single power minimal degradation and beam quality (M2). Single power that is reflected into the inner cladding may also be stripped out too.  The handling capability of the stripping power goes to 800W or at times may be even higher

Stripping the Coating

The fibers that most reputable companies supply all come with a standard  acrylate single layer coating or, in some such as the high power products, a coating that is high temperature enduring. In comparison to dual layer coatings, the coatings that are single layer are more brittle and smooth. The coating can be removed readily using the conventional tools for fiber stripping such as the Fitel S-210 Clauss or CFS-1 for 125 μm cladding diameter fiber or for larger cladding diameters the Clauss No Nik stripper is used. For fibers whose outer diameter is non-standard, it is recommended that an adjustable stripper is used.  Thermal strippers such as those that are attached to the Schleuniger FiberStrip 7030 or the Vytran FFS-2000 can be used for all fiber in a safe way.

Alternatively, chemical stripping of fibers can be done using an appropriate solvent. For example, the coating can be exposed for one minute to sulfuric acid at 120°C sulfuric acid. Before the fiber is dipped into the liquid, the tip should be sealed with a drop of glue of 2 mm in diameter or through the end fiber hole collapsing using a fusion splicer.  It is worth noting that most glue types are dissolved in this acid, but epoxies that are two-component such as the Epotek ND353 tends to dissolve in a slower manner than the coating.

It is also possible to obtain chemical stripping through application on the fiber tip, of paint stripper. The paint stripper is usually in the form of a gel so as to reduce the occurrence of out-gassing and can be applied easily using a small brush. After a minute or so, the coating becomes soft and is removed easily using a lens tissue. It is worth noting that paint stripper typically contains dichloromethane (CH2Cl2) and as such there may be restrictions by local regulations to use it. For lower quality and faster stripping, another option would be to use a normal cigarette lighter to burn the coating off. However, the fiber may end up becoming brittle hence not the best choice for stripping.

A WDM (Wavelength Division Multiplexing) is a system that uses a multiplexing (at the transmitter) and a demultiplexer (at the receiver) for the completion of the process and transmission of the signals.

The WDM is divided into three types (WDM, CWDM and DWDM) on the basis of wavelength difference among the three. The article discusses the main differences among CWDM and DWDM.

CWDM stands for Coarse Wavelength Division Multiplexing, and DWDM is the acronym for Dense Wavelength Division Multiplexing. Whether DWDM or CWDM, both are the types of WDM mechanism and have an array of differencess.

Let’s get acquainted with the chief difference between CWDM and DWDM:

  • The Coarse WDM has less than 8 active wavelengths per optical fiber whereas the DWDM has more than 8 active wavelengths per optical fiber.
  • The CWDM has lower capacity strength and hence is low in costs; conversely the DWDM possesses high capacity –this leads to an augmented price which is worth its qualities.
  • When it comes to the difference between the distance of the two, the CWDM has short range communication because the wavelength is not amplified, and DWDM has long range communication.
  • CWDM Mux and Demux systems are developed to be used in multiplexing multiple CWDM channels into one or two fibers.
  • Another major difference is that DWDM systems are made for longer haul transmittal, by keeping the wavelengths closely packed. Also, a DWDM device can transmit more data over long distances and to a significantly larger run of cable with lesser interference than a comparable CWDM system which has a shorter haul transmittal.
  • Furthermore, the Dense Wavelength Division Multiplying systems are capable to fit more than forty different data streams in the amount akin to that of fiber used for two data streams in a CWDM system.

Apart from all the difference there is one more and that is wavelength drift is possible in CWDM, but when it comes to the DWDM –precision lasers are needed to keep channels on the target.

Beyond being different from each other –these systems play different roles in the effective transfer of the signals, and thereby both are important enough.

The world knows that the physical fiber optic cabling can be a lot expensive when it comes implementing for every service separately; but this expense can be made worthy by capacity expansion using a Wave Division Multiplexing also known as WDM.

Wave Division Multiplexing technology was evolved to expand aptitude of networks that a single fiber provides. It helps because a WDM system employs a multiplexer solution at the transmitter that combines several wavelengths in concert; also in this entire process, each carries sundry signal and at the receiver –a de-multiplexer helps in splitting them apart. Both Mux and Demux are passive and thereby require no power supply.

Types of WDM

Currently there are many kinds of standardized WDM in existence. The types / kinds of Wave Division Multiplexing are:

  • General WDM (that may include 980/1550 WDM and 1310/1550 WDM).
  • CWDM (such as CWDM Mux and Demux module and CWDM OADM module).
  • DWDM (including 50GHz, 100GHz, 200GHz DWDM mux/demux module and DWDM OADM module).

How WDM works?

The operating principle of WDM is easy and understandable. Wave Division Multiplexing is akin to the prism in the operating principle; as a prism separates white light into seven different colored rays, similarly a WDM system uses a multiplexer at the transmitter to join different signals together, and has a demultiplexer at the receiver end for splitting the signals apart. All you need is a right type of fiber optic cable, and it is possible to have a WDM device that can do both simultaneously, and can act as an optical add / drop multiplexer.

The first WDM systems (which were demonstrated with optical fiber in the early 80s) combined only two signals; however, modern systems can handle up to 160 signals. In short, WDM systems can expand the capacity of the network while accommodating many generations of technology development in optical infrastructure without having to revamp the backbone network; this quality plays in its popularity with telecommunications companies.
