Fiber Optic Isolators

Posted on June 11, 2014 by admin

1 introduction
Semiconductor lasers, optical amplifiers and optical fiber lasers from the connector, fusion point, filter the reflection light is very sensitive, and may cause performance deterioration and even damaged, requiring a optical isolator to prevent the reflection of light. The optical isolator is permitted only light along one direction through and in the opposite direction blocks light through the optical passive devices. In the optical fiber communication, optical fiber reflection light through the optical isolator can be a good isolation. In the fiber laser applications, optical isolators are usually used in the optical path to avoid the light path of the light source, the echo on the pumping source and other light emitting device causes interference and damage. Isolatorsa€?s isolation represents the optical isolator to echo the isolation (blocking) ability.

2 optical isolator principle
Optical isolator using magnetic optical crystal Faraday effect ( also known as the Faraday effect ). In 1845, Faraday first observed with optical material under the action of magnetic field to make the material in the direction of polarization rotation, therefore often called the Faraday effect. In Faraday effect, the rotation of the polarization direction direction and magnetic field, and the orientation of the light transmitting is independent of the forward and reverse, and we usually in the index of refraction, reflection phenomena seen in the reversibility of optical path difference. Along the magnetic field direction of transmission line polarized, the polarization direction rotating angle ??and magnetic field strength of B and L is proportional to the product of the length of the material, the proportion coefficient is what we often say that the Wilde constant. Optical isolator based on polarization characteristics can be divided into polarization-independent and polarization dependent type. These two kinds of isolators are used with the Faraday effect in magneto-optic crystal, Faraday magnetic medium in 1~2?? m wavelength range usually adopts the optical loss low yttrium iron garnet ( YIG ) single crystals. Model of input and output of the fiber optical isolator has fairly good performance, the minimum insertion loss of approximately 0.5 dB, the isolation of up to 35??? 60 dB, a maximum of 70 dB. The optical isolator using most still is polarization independent type, its principle is shown in Figure 1, using the forward and reverse transmission optical path is inconsistent, it is this time signal transmission is not reversible, thereby forming isolation. The typical structure of only four major components: the magnetic ring, a Faraday rotator, two pieces of LiNbO3 wedge angle piece, with a pair of fiber collimator, can be made into an in-line optical isolators.
Positive transmission: the parallel light beam from the collimator, into the first wedge angle piece P1, beam is divided into o light and e light, the polarization direction perpendicular to the propagation direction, forming an included angle. When they pass through 45o Faraday rotator, emitted by the o light and e light polarizing surfaces of respective to the same direction of rotation 45o, because the second wedge-shaped plate P2 crystal axis relative to the first wedge angle piece is just in a 45o angle, so o light and e light is refracted into a small space, synthesis. Parallel light, and then by another collimator is coupled to the optical fiber core. In this case, the input optical power only a very small fraction of outage, this loss is called isolator insertion loss..

Posted on June 10, 2014 by admin

Cable technology made a great progress way within the last few decades. Today, it makes it possible for signal transmission (audio, video, TCIP, voice-over IP, etc) from the source with an intended product. Advancements in cabling technologies have made two-way communication, internet, and audio/video transmission a lot more efficient and seamless.

Optical Fiber Cables

Optical fiber is oftentimes intended for telecomm purposes for its portability and flexibility. In addition it makes it possible for more efficient long range communication than electrical wires. Furthermore, each fiber can have several independent channels, each utilizing a different wavelength of light. And because fiber optic cables can carry so much more information, aren’t subject to the electrical interferences and are not flammable, they are also ideal for short range uses, such as creating a network within a residential or business unit. Fiber optic systems could include multi-media boxes and outletsconnectors, enclosures, adaptors, boxes, jumpers, plug and play cassettes, splice trays, and several bulk cables.

Raceway

Raceway is actually an conduit allowing cabling to remain routed across intended sectors of a unit. It enables better cable and wiring management because it provides cabling to always be stumble upon a wall. This gives for protection for the cable (from being damaged) in addition to people (from tripping). It also produces a far more aesthetic and professional appearance than having unsightly cables running across a wall. Raceway systems include boxes, station outlets, raceway fittings, surface raceways, and raceway tools.

Modular Connectors

Modular Connectors may be the standard generally used by many electrical connectors. Frequently, this really is noticed in both residential phone connectors together with Ethernet cables. The small structure and size these connectors produces easy plugging and unplugging, limiting the amount of time needed for connecting, disconnecting, and reconnecting. Certainly, this same structure also results in easy wear and tear, which leads to loose connections that can be easily disconnected as it takes only a tiny amount of pressure to get a plug to drop out of a wall jack.

A variety of adaptors and couplers are accessible for modular connectors. These enable you to connect a single male-end connector in an adaptor with multiple female-ended connectors to let for multiple sources to get in touch to your single jack. They can also be used to connect different types of connectors to a modular connector, or to filter out radio frequencies..

Empty wine bottles sell things

Posted on June 6, 2014 by admin

You might be surprised to discover that there are hundreds, even thousands of types, labels, grades and uses for wine. Even if you assume wine is not for you, it could just be you have yet to discover the right bottle. The information that follows gives you a great foundation for choosing wines.

Rely on Windex if you spill wine on your clothing. Windex has the fighting power to eliminate wine stains immediately, much better than soap and water will. Make sure that you use this as quickly as possible, as waiting will only make it tougher to get rid of the stains.

Use wine to create an impressive sauce for beef dishes. Start by adding s tablespoonful of butter and a dash of red wine to your saucepan. Wait until the sauce becomes thicker and keep in mind that the alcohol will evaporate as you cook the sauce. Pour over the beef and enjoy.

Not all wine is meant to be aged. Do some research on the wine type you have and how long it will stay good. An example of a wine that ages wonderfully is Bordeaux.

In order to reuse a bottle, or for easier recycling, be sure you know how to remover the label from an empty bottle. The easiest and most common method is to pop the bottle into the oven and then carefully peel back the label once the bottle is hot.

Take the time to plan if you are thinking about going to a winery. Before departing, arrange for a designated driver and determine how much money you will spend. Also, be prepared to describe the wines that you prefer and have questions on hand for the guide.

The most obvious differences between red and white wines are the grapes they are made from and their colors. Red wine is made from purple grapes, which give it a strong body. On the other hand, white wines are made out of lighter green grapes. There is more to the difference than that, of course.

It is easy to maintain the freshness of Spanish wines, but different types require different strategies. Rioja, for example, can last up to seven years after it is bottled. Keep this particular bottle of wine in a cool and dark location that is convenient for you so that you can enjoy it anytime you want.

Be certain your wine tastings are done in a quiet, relaxed setting. To experience the wine’s true flavor, the atmosphere should be soothing. Rowdy environments can be distracting and cause you to neglect the task of observing the wines.

Get to know the people who serve you at the establishments where your frequently purchase wine. They may be able to keep you apprised of special labels or sales that may be available to their private clients.

There are many wines to make your selections from, so take your time to get to know them first. You will soon become an expert if you use the tips you just read and keep trying different wines. It’s important to enjoy yourself — and drink in moderation..

The use of beer bottles

Posted on June 5, 2014 by admin

Homemade beer is far different from the regular commercialized beer bottles you see being offered on elegant bars and restaurants. The procedure of making it is simple and does not need too much equipment or technological innovation to do so. If you are interested in flavored and consuming a homemade beers, it would be recommended to buy microbrewery equipment. This will be your first step that you must take before you continue with the primary procedure.

After that you have to search the internet what would be the possible kits you need to buy when you do beer-making at home. This is very important. At least you will know what should come within a kit that are necessary in beer-making and what are those that you can do without. For that purpose would be to start canvassing for manufacturers or organizations promoting wine-making kit on the internet or on site. Do not be fooled by too much buzz or advertisement an organization or product might be using in order to advertise their beer making kit. You should look on every bit of details before considering a product or organization.

And, when you would be selecting the product or organization to buy a beer-making kit from always make a record. You need to make a record of the organizations promoting such kit, because what exactly they are offering at what costs. Finally, make your choice by looking at the various options that you have. One good tip, know what your price range is and how much you are willing to invest in a beer brewing supplies. In this way, you would be limited to your budget and not be investing on something which you do not need at all. If you are too eager of getting a kit, you should do a background check on the organization and see what other clients have to say about the kit, the organization and client support. This would give you a good piece of information as to what to expect when you opt for selecting the right beer-making kit.

Now that you already know what to look for in a beer making kit, the next step you need to take is to select what type of ingredients you want create bottles from. The choice would be reliant upon your choice and what your flavor is. If you want to be more trial, you can create a unique flavor through modifying the ingredients or including a key component or phase to the fermentation procedure..

Brief description of the variable optical attenuator

Posted on June 3, 2014 by admin

An optical attenuator is an electronic device commonly used to decrease the level of power of an optical signal in a fiber optic communication system. In fiber optics, attenuation is also called transmission loss. It is the reduction in light signal intensity with respect to the distance traveled by the signal in a transmission medium. Attenuation is an important element to limit the transmission of a digital signal traveling in large distances. An optical attenuator reduces this optical signal as it travels along a free space or an optical fiber.

Optical fiber attenuators may employ several principles when used in fiber optic communications. One common principle is the gap loss principle. Attenuators using this principle are sensitive to the modal distribution ahead of the attenuator. Thus, they should be utilized at or near the transmitting end. If not, the attenuators could establish less loss than intended. This problem is avoided by attenuators that use absorptive or reflective principles.

There are three basic types of optical attenuator: the fixed attenuator, step-wise attenuator and the continuously variable attenuator. Fixed attenuators reduce light signals by specific amount with negligible or no reflection. Because signal reflection is not an issue, fixed attenuators are known for more accurate data transmission. Important elements associated with fixed attenuators include the flatness over a specified frequency, range, voltage standing wave ratio (VSWR), amount of attenuation, average and peak power-handling capability, performance over a specific temperature, size and height. Fixed attenuators are also often used to enhance interstage matching in an electronic circuit. Thorlab’s fixed attenuators are available from 5 dB to 25 dB. Mini-Circuits’ fixed attenuators are packaged in rugged plug-in and connector models. They are available in both 50- and 76-ohm models ranging from 1to 40 dB spanning DC to 1500 MHz.

In variable optical attenuators (VOA), resistors are replaced with solid state devices such as the metal semiconductor field effect transistor (MESFETs) and PIN diodes. VOA attenuates light signal or beam in a controlled manner, thus producing an output optical beam with different attenuated intensity. The attenuator adjusts the power ratio between the light beam coming from the device and the light beam entering the device over a changeable rate. VOA is usually used in fiber optic communication systems to regulate optical power levels in order to prevent damages in optical receivers which may be due to irregular or fluctuating power levels. The price of commercial VOA varies depending on the manufacturing technology used. Some of manufacturers of VOA are Timbercon and Arcoptix.

Timbercon claims that its optical attenuator units produce precision levels of attenuation, with the added flexibility of adjustment. Timbercon’s variable attenuators are available in single mode and multi-mode versions. They have low insertion loss and back reflection. The attenuators are also compact in size and available in multiple packaging options. Arcoptix’s electrical adjustable variable attenuators are a liquid crystal device which allows the precise control of the attenuation of beams traveling in free space. These attenuators can be adjusted in milliseconds with a simple square wave bias between 0 and 10 volts.

In the future fiber optic can become the better medium for the new communication

Posted on May 30, 2014 by admin

In the modern era like now, you will see the internet connection which is provided by the copper wire and the fiber optic wire. At first, the internet connection is supported by using the copper wire. However, after the fiber optic wire was introduced, many internet service providers move to use the fiber optic wire.

Many internet service providers believe the wire can become the better medium for the new communication in the future. The providers use the wire for the internet connection with the high-speed, cable connections for many uses, and the telephone. Like other technologies, this wire has the advantages and disadvantages.

The fiber wire uses the light waves in transferring the data. It is made from the plastic fibers as the core of the cable or the glass material. This material then is covered with the cladding layer which is designed to reflect the light back to the core and the buffer coating protecting the fibers from any damage which can be harmful for the wire system.

By using the wire, you can enjoy some advantages such as the high-speed. You will get the faster data transmission if you use this wire. Many users state that they feel amazed for the amazing speed provided by the wire. You will not face the problems which you usually face when you use the copper wire like the RF interference. Usually, the users of the coaxial cabling will face the problem in the data transmission because of the Radio Frequency. This technology is not susceptible for the RF interference.

When you use the fiber optic wire, you can enjoy the data transmission in the long distances without experiencing the data loss. However, this technology also has the disadvantages for example the costs. If you use this technology, you need to pay the costs which are more than the double price of the broadband connections. Some people will not be able to get this technology because it is not provided in all areas. It can be said that it is the biggest disadvantages.

What Are the Benefits of Fiber Optic Signal Routing?

Posted on May 29, 2014 by admin

Fiber optic cables have been a big part of the information age. When it comes to high-speed Internet and high-definition TV in homes, all of the latest advances in Internet speed and HD video start with the fiber optic cables laid by communications companies over the last couple decades. The reason these large corporations invested in this technology is because of how reliable, secure and quick it is. And considering how many users are involved, having a stable and efficient information infrastructure is obviously important.

So if the communication companies are operating on what can be called a “macro” level, linking together customers across great distances, could this cabling be important and useful on a more “micro” level? For hospitals, academic institutions, or businesses, KVM and signal routing throughout their operation is also vital. For some such venues – the aforementioned medical campus or perhaps a government or defense outfit – maintaining an ultra-secure means of communication and signal routing is key. It’s so crucial that typical signal routing solutions, such as Cat5e/6 cables, just won’t cut it. The information being moved is too sensitive to be compromised. And that’s where fiber optic cables come in.

There are several key benefits to this upgrade. First and foremost, fiber optic cables are immune to electromagnetic interference, allowing them to provide secure transmission and routing. Second, fiber optic cables eliminate the need for bulky cabling and additional equipment to boost video signal, both of which are helpful for routing through small areas. Third, these cable extensions extensions offer long-distance routing solutions.

That level of security is important for national security in defense applications. In medical and academic venues, that’s important for privacy and confidentiality. Businesses are looking for similar protections, whether that’s to ward off hackers, corporate espionage, or other breaches of security. And with long distance needs, these cinnections allow large government, medical, academic and corporate campuses to install a stellar communications system that handles all of their criteria.

Fiber optic cables also deliver uncompressed signals for when every pixel truly matters. Think about a doctor examining an MRI read out, or security professional trying to identify a criminal caught briefly on camera; these are just two common examples when maintaining pristine visual clarity through uncompressed signal routing is essential.

Nowadays, you can find many different kinds of lighting that will be perfect to increase the beauty of your landscape. One of the best ideas will be installing fiber optic lighting. This certain lighting allows you to pinpoint certain spots where the light will shine. This is a very great idea to produce astonishing visual landscape effects. Besides, this certain kind of lighting does not transmit electrical signal so it is safe enough to be installed in your landscape even if you have plants, pets or children. Here are some tips that you could take before buying certain lighting for your landscape.

First, you need to make a diagram of the area that you plan to light. Do not worry. You do not need to make a very detail drawing like a professional do. Even, your simplest drawing will deliver great help in buying the right material.

Second, imagine the kind of effects that you want to create by installing the fiber optic. Determine whether you are going to illuminate your pathway, the edge or the flower bed, or driveway. You can also create starry effects by using this certain kind of lighting. Add the certain effect that you desire to have to your diagram.

Third, you can continue to find the best place of the illuminator. This is a certain part that is responsible to deliver light to the fiber optics. You should place the illuminator in a wide open area in order to give the heat out properly. Moreover, the cable lines of the fiber optic should also be less then 40 feet from the illuminator. It is very important to help you get consistent lighting.

Fourth, you should also figure out how much cable that you need to purchase. It will be better for you to measure total distance from the location of the illuminator to various light points. Therefore, you can buy the cable in adequate amount to handle the entire lighting system you need to install in your landscape.

Fifth, you need to compare the cost. Try to find more information about the price of longer fiber optic cables as well as the cost of more illuminators and shorter cables. You can choose the most efficient one for your needs.

Sixth, you can now buy the fiber optic cable as well as the fixture. In order to make sure that you are having enough cable for this installation, it will be better for you to purchase cable with an i8 inches service loop left at each end of the cable.

A brief description of the optical fiber coupler

Posted on May 23, 2014 by admin

When testing loss in a fiber optic link, some basic principles must be kept in mind all the time.

1.The testing wavelength should always be the same as the working wavelength. Because optical fiber loss varies with light wavelength, you will get incorrect result if your measuring wavelength is different from the actual working wavelength. For example, if a system is designed for 1550nm but you test it with 1310nm light source and power meter, the result will not be correct.

2.The testing light source should be the same as the intended working lightwave equipment light source. If the system is designed for a LED source, you should test it with a LED source. If the system is designed for multimode laser light, you should use a multimode laser light source for testing. This is also true for single mode laser light source.

Fiber optic equipment used in a loss testing

In a basic loss testing setup, four types of test equipment are needed. They are the light source, the power meter, the reference patch cables and the adapter (mating sleeve).

Here are some considerations when choosing your equipment.

The light source should have the same wavelength as the operating equipment, proper mode (multimode or single mode, should be same as the operating equipment), type (LED or laser, same as the operating equipment) and proper connector.

The power meter should have the same wavelength as the light source, proper connector and calibrated.

The reference patch cables should be high quality with know loss, proper connectors and be the same type as the fiber plant being tested.
