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.

How to Find Affordable Automobile Insurance in Arizona

Finding affordable automobile insurance for your Arizona vehicle may not be a difficult as you think. Shop around on the Internet for alternative quotes from various companies.

There are discounts and savings that you may not be aware of as follows:

1. Multi-Line Discount: Insurance companies offer discounts to policyholders that have more than one line of insurance coverage with them. Seek insurance quotes from the insurance company that is currently writing your homeowner or renter’s insurance policy. Be sure to make them aware that you have other lines of coverage placed with them, especially if you’re seeking quotes over the internet.

2. Non-smokers: Non-smokers are a more favorable risk to insurance companies than non-smokers. Now would be a good time to kick the habit for both your health and your pocket.

3. Vehicle Safety Features: Newer vehicles come equipped with airbags and automatic seatbelts. These features and others like anti lock brakes will server to lower your auto premiums.

4. Higher Deductibles: How much can you afford to pay out of pocket in the event of a collision or comprehensive loss? If you can afford to pay the first $500 or even $1,000, you will earn a premium discount for the higher deductible. Get alternative quotes with various deductibles. Make sure the premium savings is worth the extra out of pocket expense. Remember, the deductible applies to each loss, not just the first one.

5. Accident Free: How is your driving record? If you have a clean driving record without accident or points, ask your insurance company for a clean driver discount. Companies may call it by different names, but make sure you specifically ask the question how much is my clean driving record saving me?

6. Multiple Auto: Insuring two vehicles with one insurance company is cheaper than two separate policies. If you have more than one vehicle, it only makes sense to cover them under the same policy.

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.
