5 Reasons Why Fiber Optic Patch Cables Are Beneficial

In the modern era of technology, fiber optics has started to play an important role in data transfer and communication. The data transfer that happens in these cables is based upon the technology of optical networks. Light waves are encoded and modulated to send and receive data. And fiber optic patch cables play an important role in completing the end-to-end connection of systems using this technology.

First of all, let us understand what makes the optical fiber communication important. The fiber optics makes sure that certain desired properties of any communication are satisfied. And the quality that they maintain with respect to these properties makes using these network cables desirable.

Interestingly, the fiber optic patch cables require being compatible with all these properties to keep up with the network quality. So the attributes desirable of the fiber cables are also good for the patches. Some of the important properties are listed below.

Rate of data transfer: Data of high volume can easily be transferred using the optic cables. In fact, with the mainline network cables, one can transfer terabytes of data every second as done in case of the worldwide Internet exchange data. The same can be said about the fiber optic patch cables. The bandwidth of these cables is extremely high.

Speed of communication: The physical communication happens over modulated waves of light. As a result, the speed of communication is extremely fast with the fiber optic networks. One can use these networks to access real time data across the globe. The patch cables are compatible with the speed and they can transfer data at the same speed as the main network cable.

Absence of attenuation: Attenuation of signal is a critical factor in most of the networks. However, for an optical network, this is practically absent. The data can traverse along the network with no amplifier installed in the route. The patch cables also do not attenuate the data.

Accuracy of transferred data: The transfer of data takes place with a high degree of accuracy. The data suffers from practically no external hindrance. No signal coming form outside really changes anything about the data. As a result, the data transfer preserves the accuracy of information exchange. The fiber optic patch cables maintain high levels of accuracy when it comes to data transfer.

Security factors: Fiber optic patch cables are as secure as the overall optical fiber network. They are extremely difficult to break into and hence the possibility of data leaking out of the network is practically minimal.

All of the above makes using fiber optic patch cables beneficial when it comes to real life application. Make sure that you have got the right patch with the right length and aperture, and you are all set to enjoy the benefits of a secure and high speed communication.

Picking Hairstyles For Your Quinceanera Or Wedding

Is not it insane how many options there are out there for you to do your hair? I mean where do you start. You want to look your best the day of your Quinceanera so you want to pick the right hairstyle. I feel your pain. But there are many sources available to you on your journey. So do not panic, relax and let's journey together towards picking the right quinceanera hairstyle.

Length of your hair

The style that you pick will depend on the length of your hair. So here are a couple of suggestions for short hair and for long hair.

Start by separating your hair into 3 low ponytails. Then pin down each of the ponytails into a bun, they should all look like they blend in together. Add some elegant barrettes and your set. Always use extra hairspray to arrange the loose ends.

The Curlier the Better

If you are going to have dams stand in your Quince you may want them to all have the same hairstyle. A traditional hairstyle is to get them to wear their hair curly especially if your hair will be straight. Personally you should go with a French twist, it's nice and elegant and the style looks great on film.

Stay away from half pony tails or random chongos. Get advice from other hairstylists in your area and make an appointment ahead of time. Also you may want to get your hair down as early as possible in case you do not like the style you have time to change it. Let me be the first to congratulate you on your Quinceanera hairstyle.

7 Different Type Of Speech Introductions

Unless a speaker can interest his audience, his effort will be a failure. If your topic is not one of extraordinary interest, your listeners are likely to say to themselves, so what? Who cares? A speaker can quickly lose an audience if she or he doesn’t use the introduction to get their attention and clicking their interest in getting the initial attention of your audience is usually easy-even before you utter a single word. After you are introduced, turn to your audience and they will normally give you their attention. If they don’t, then patiently look towards the audience without saying a word. In a few moments all talking and physical commotion will stop. Your listeners will be attentive. You’ll be ready to start speaking. Keeping the attention of your audience once you start talking is more difficult. Here are some methods used most to keep them Interested.

#1: Relate the topic to the audience-

People pay attention to things that affect them directly if you can relate the topic your listeners they’re much more likely to be interested in it.

#2: State the importance of your topic-

Presumably you think your speech is important, tell your audience why they should think so too.

#3: Startle the audience.

One sure fire way to arouse interest quickly is to startle all your listeners with an arresting or intriguing statement. This technique is highly effective and easy to use just be sure the starling introduction relates directly to the subject of your speech.

#4: Arouse the curiosity of the audience-

People are curious. One way to draw them into your speech is with a series of statements that progressively whet their curiosity about the subject of the speech.

#5: Question the audience-

Asking a rhetorical question is another way to get your listeners thinking about your speech sometimes even a single question will do.

#6: Begin with the quotation-

Another way to arouse the interest of your audience is to start with an attention getting quotation. You might choose a quotation from Shakespeare or Confucius, from the bible or Talmud, from Shakespeare, song, or film.

#7: Tell a story-

We all enjoy stories-especially if they are provocative, dramatic, or suspenseful. To work well as instructions, they should also be clearly relevant to the main point of the speech. Used in this way, stories are perhaps the most effective way to begin a speech.

With this information you should be on your way to be writing some amazing intros. Good luck with your speeches!

Privacy Issues Surrounding Biometric Technology

The terrorist attacks on the World Trade Center have provoked in-depth discussion and study of existing security measures, their deficiencies, and how to enhance security to prevent similar terrorist attacks from occurring in the future. Biometric technology has risen to the top of the list as a possible solution. The government is not the only entity exploring biometric security systems. The financial services industry see biometrics as a way to curb identity theft. Biometrics are intrinsic physical characteristics used to identify individuals. The most commonly used biometric is fingerprints but others include, handprints, facial features, iris & retinal scans, and voice recognition.

Soon after 9/11 there were calls for the issuance of national ID cards containing biometric information on an RFID chip implanted on the card. The argument is that national ID cards will increase security by identifying individuals with their unique fingerprints which are much more difficult to counterfeit than standard photo ID cards. There is also a movement toward biometric passports. It looks like biometric passports are coming soon. National ID cards may follow.

Biometric identification is nothing new. Humans have been identifying other humans biometrically since the beginning of time. You recognize people you know by their facial features, their voice, and other biometric features. What’s new is introducing technology into the mix that compares a given biometric with a stored database of biometrics to verify the identity of an individual. An individual place their finger on a fingerprint scanner and the image is compared with the database to verify the person’s identity. Promising as it is, biometric technology has not been without hiccups but biometrics are advancing quickly and becoming more and more prevalent in security systems.

Fingerprints are the most commonly used biometric identifiers. The National Institute of Standards and Technology (NIST) conducted a study that showed single fingerprint biometric systems had a 98.6 percent accuracy rate. The accuracy rate rose to 99.6 percent when 2 fingerprints were used and an almost perfect 99.9 percent when 4 or more fingerprints were used. The study results show that biometric identification is nearly perfect which is not surprising given the uniqueness of human fingerprints.

The US-VISIT program, which is an acronym for United States Visitor & Immigrant Status Indicator Technology, currently requires foreign visitors to the US to present a biometric passport containing 2 fingerprints and a digital photo for identification purposes before being granted admission to the U.S. Of course the biometrics are compared against a vast network of government databases full of known and suspected terrorists and other criminals.

On the surface biometric technology may sound like a panacea but it’s use has raised significant privacy concerns that need to be addressed. Here are six major privacy concerns: storage, vulnerability, confidence, authenticity, linking, and ubiquity.

Critics wonder how the data will be stored and how vulnerable it will be to theft or abuse. Confidence issues center around the implications of false positives and false negatives. Can the biometric data be used to link to other information about the individual such as marital status, religion, employment status, etc.? And finally ubiquity. What are the implications of leaving electronic “bread crumbs” to mark a trail detailing every movement an individual makes?

Until these issues are addressed, privacy advocates will lead a charge to resist biometric technology claiming it as a way for the government to assume a “Big Brother” type of rule as described in George Orwell’s novel 1984. But protest as they may, it’s likely national security concerns and the ability of biometric systems to enhance the security of US border and possibly prevent another major terrorist attack will win out over privacy concerns.
