Global Fiber Optic Components Market 2017-2021

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.

Understanding the Use of Optical Fused Coupler, MUX & DEMUX WDM

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.

WDM And The Modules Based On It: The Need Of The Hour

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.

Two Types Of Polarization Beam Combiners & Splitters

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.

2. 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.

Learning the Different Coating Stripping Methods

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.

Know the Difference between CWDM and DWDM

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.
