When it Comes to Fibre Optics Don’t Think Point to Point, Think Endless Possibilities
Article by Zorik Danelian
High speed digital transmission of information, be it just data, audio or in the form of video stream over long distances is becoming more and more common in this age of Information Technology. This digital information can originate from a PC, instruments of all kinds, audio files or digital video in the form of DVI, 3GSDI or HDMI.
Copper cables can not carry this large amount of digital data for long distances, without losing critical amount of data, hence the need for Fiber-Optic connection. However it is not just the Fibre Optic cable that is required for digital transmission. Sources and their destinations will be required to comply with any number of protocols, including DVI, HDMI, Displayport, Firewire, 3GSDI, USB and VCSEL Transceivers.
Fibre Optic Extenders that ensure both ends of communication link “understand” each other are becoming more common. These extenders are mainly available with a predefined cable length of up to 100 meters. What if you require digital communication over longer distances? After all Fibre Optics can carry digital information for Kilometers. To achieve this aim many suppliers now offer Detachable Fibre Modules. These modules will sit at either end of the digital communication link and allow Fibre Optic cables of varying sizes to be connected to them to carry the data over long distances. These Detachable Fibre Modules not anly carry DVI, USB or HDMI data but can also be daisy chained if multiple points of destinations are needed.
In addition it is important to note that Fibre Optic cables are completely passive, good for EMI and electrical isolation and are lossless, ensuring that whatever digital data is sent is also received.
Applications for these types of communication are varied, including Digital Signage, LCD panels, Broadcasting, Projectors, LED signboards and Instrumentation, especially in heavy industries where electrical isolation for connections between two points is of utmost importance.
So, we have established that Fibre Optic cables are ideal for long distance point to point digital communications but what if you have one source of data but you want to display it on several points? Examples could be presentations at exhibitions, advertsing in say the underground or showing video at sports grounds on to several displays. This is where Fibre Optic Distributors come in. These products can take several sources of information and transmit it to a number of different destinations, like LCD screens. For example you could have digital HDMI pictures coming from two set top boxes and be variously displayed on 4 screens of your choosing at any one time.
It is also possible to use Fibre Optic Matrix Routers to receive information in one format and convert it on to another format. This could be DVI to HDMI, 3GSDI to HMI and so on. There are Matrix Routers that can take up to 36 different inputs and convert them to 36 different types of outputs extending the possibilities of applications for sending digital information.
Another example of products available in the market is a Media Player. A Media Player can store information such as vedio data or a presentation and transmit it at a specified time to a predefined display. The whole system can be controlled and updated through the internet, allowing you to show what you want, when you want and to the audience of your choosing.
In conclusion when it comes to long distance digital communication, just don’t think point to point or a single format. Think endless possibilities, as there are products in the market that can make this a simple task.

The Fiber Optics Technology: Familiarizing Yourself With Fiber Optics Tools And Transmission
By: Tony Farinholt
Posted: Feb 02, 2011
]]>
Fiber optics technology has been generally known for its transmission and communication capability. It is likewise being used in the internet. Although it is not a novice when it comes to communication, numerous people are just unaware of it. We are utilizing it as we look through the internet and as we speak to people over the phone but we don’t know that the technology behind it is the fiber optics technology. Optical transceivers are the building blocks of this kind of technology.
The original investigation of optical transceivers was performed by John Tyndall. He used a ray light and a jet of water. due to this, he was able to confirm that light utilizes an interior reflection in order to follow a course. That was the start of the several studies which lead to the inexorable development of the fiber optics technology.
The principal belief that is working behind the fiber optics technology is total internal reflection. Every time we mention optical fibers, we frequently envision a lengthy glass or plastic cylindrical fiber. The material should be capable in reflecting beam from within. And moreover, it must by no means drop its intensity. The exterior shell is comprised of two parts. These are the cladding and the outer cladding. Cladding is an optical fiber capable in returning light. A plastic material comprises the exterior one which is used in protecting the inner fiber. So as to have an optical line, a hundred fiber is necessary. Try imagining it. It is actually identical to the line which has several threads.
To further recognize the fiber optics technology, one needs to take into account that it is running via the internal return of beam. Information is sent out through this mechanism. Information is converted into pulses of beam. Electric signals in fact portray a big part in the transmission course. These electric signals will be converted into the optical signals and at the final part of the course, it will be transformed back into electric signals.
The benefit of fiber optics is that it enables a greater bandwidth in contrast to the conventional type of communication. This will just mean that there will be additional information to be transmitted. It has low interference when being contrasted to metal wires. Also, it is less bulky. Fiber optics technology can likewise leave out the analog system of data transmission. SFP modules give a selection of options for fiber needs in order to wholly reach the advantages mentioned above.

How To Install A LightCon LC Connector To A Multimode / Singlemode Fiber Optic Cable Presented By American Fiber Optic
Fiber optic technology involves a glass or plastic fiber that carries light along its length. Light is kept at the core of the fiber by internal reflection. Light can enter the fiber, but it cannot leave except at the ends. Fiber optic gun sights catch any available light and channel along it to the end of the cylinder. The TruGlo Brite-Site features CNC milled steel construction, and the fiber optics contrast: red in the front and green in the rear. TruGlo sights are made in such a manner that the shooter can see them clearly, but because of the clever design, the sights cannot be seen from the target or downrange. Using TruGlo sights in low light conditions, youll get a much clearer sight picture. In fact, these sights will pick up any available light at all, including moonlight. Available for all models of Glock pistols, these sights make a world of difference. If you want to improve your shooting accuracy in low light conditions, consider upgrading to TruGlo fiber optic sights.

What Fiber Optic Supplies Do You Need To Clean A Fiber Optic Connector?
By: Colin Yao

First, let’s understand why a fiber optic connector needs cleaning.
You may never need to clean the RJ45 connector for your computer’s Ethernet network connection, then why do you need to clean a fiber optic connector if it serves the same purpose as a networking connection?
While, the answer lies in how optics work differently than electronics. In electronics, as long as you have a contact between two connectors, they work perfectly; or at least most of the time.
But for optics, light beams travel in straight lines, they bounce off whenever they hit anything and thus loss their energy.
So in order for a light beam to carry the information signal and travel thousands of miles of optical fiber, its path must be kept crystal clear, including fiber optic connectors in the network.
What part of a fiber optic connector should be cleaned, exactly?
OK. Now comes the critical part. What part in the fiber connector needs cleaning, exactly? The short answer is the ferrule’s body and its end face. But what exactly is a ferrule?
Ferrule is a cylindrical and also the most critical part in an optical fiber connector. It is usually made from stainless steel or Zirconia.
Zirconia is a type of white colored ceramic which is an extremely refractory material. It offers chemical and corrosion inertness to temperatures well above the melting point of alumina. Zirconia is the preferred material for high quality fiber optic ferrules.

Ferrules have a tiny hole in the center which holds optical fiber in place. Then the fiber is scribed and precisely polished to flush with the end face of the ferrule.
Two fiber connectors can then mate to each other with a mating sleeve. When mated, two ferrules’ end faces contact each other perfectly and thus pass light from one fiber to another.
Ferrules get dirty from dust, stain and debris made by constant plugging and unplugging after having been used for a while. These contaminations will block the light path and thus seriously reduce the light power and may disable the network connection.
To get a better sense of how a fiber optic connector could be contaminated, look at this tutorial: http://www.fiberoptics4sale.com/Merchant2/fiber-optic-cleaning.php
Is there only one method for fiber connector cleaning?
There are many different ways to clean a fiber optic connector. They are not exclusive but rather complementary to each other. When one method failed, you can always try another method. And that is why there are so many fiber optic supplies for cleaning fiber connectors available on the market.
1. Air spray. Air dusters are used to blow loose particles from optical fiber connector end face. Optic grade is more expensive. Air spray is a non-abrasive fiber optic cleaning method.
2. Lint-free wipes with isopropyl alcohol. The operator folds the lens paper (such as the lint free wipes) into 4~6 layers and lay it flat on a table. He then holds the connector vertically straight and cleans the end face in figure 8 motion.
3. Reel fiber optic connector cleaners. Connector reel cleaner is a dry cleaning method with a quick, reliable operation and uniform results. They use 2 micrometer weaved polyester cloth to clean optical fiber connectors. This is an abrasive fiber optic cleaning method but pad underneath cleaning cloth mitigates this significantly.
4. Stick or swab type cleaners. These specially built Cletop sticks come in 2.5mm and 1.25mm versions. They are designed for dry cleaning fiber optic connector mating sleeves, bulkhead adapters and receptacles.
5. In-situ cleaning. This semi-automated fiber optic cleaning method is specially designed for fiber optic connectors plugged in patch panels and hardware devices.
6. Pre-saturated or soaked wipes. Pre-saturated wipes are good for cleaning glass fiber or connector end faces. They are available in a convenient pre-saturated towelette. The towels are durable and non-linting. Pre-saturated wipes are a convenient option for field use.

Fiber Optic Training – Fundamentals of Optical Fiber Communication
Light enters the core of the optical fiber and strikes the core/cladding interface at an angle. If this angle is greater than the critical angle, then the ray will reflect back into the core thus experiencing total internal reflection. This ray of light will continue to experience total internal reflection as it encounters core/cladding interfaces while propagating down the fiber.
