Ebay is a great site and is used by many to buy and sell new and used Items. It truly is the worlds Largest Garage Sale Unfortunately when an online site becomes as big and popular as E-Bay the scam artists seem to just naturally follow. These Scam artists will often try to steal your Idenity and get your bank or credit card information in addition to your E-Bay Id and Password

A Typical Ebay Scam Artist will send you an e-mail requesting that you update your account. Often this request to update your account is made under some false pretence like it is suspended or has been suspected of Fraudulent use. Here is a Copy of a recent Ebay Scam E-mail I received http://ewguru.com/ebay-scam. You will notice the E-Bay Link on this page looks real. Don't click it. You can however do a right click properties and notice that it is in fact a phony link.

E-bay has an excellent online Tutorial that teaches how to spot and protect yourself from spoof e-mails

Here are 8 Surefire Ways to Spot an EBAY Scam E-Mail and Protect Yourself from Identity Theft

1 - Wrong E-Mail Address

Any E-mail Sent to an E-mail Address that is Not Your Primary Ebay E-mail Account is more then likely a scam.

2 - Fake links.

While many emails have links included, just remember that these links can be forged too. After you click on the Link a Real E-Bay Address should appear. To determine if the Web address in your browser is a real eBay address, look for ".ebay.com" immediately before the first "/".

3 - Requests Personal Information

Any E-mail that requests you enter personal information like User ID, password or bank account number either by clicking on a link in the E-mail or completing a form within the e-mail are a strong indication the e-mail is a SCAM

4 - Urgent Subject Lines

Subject likes * * * Please Verify & Update Your Account * * *

5 - Generic greetings.

Lot's of emails begin with a Greeting, such as: "Dear Ebay member instead of the Name you used when you registered for your account

6 - Scare to Action

Many Fake emails try to trick you with the threat that your account is in jeopardy if you don't sign in and fix it NOW!

7 - HTML Website Fakes

Emails that appear to be websites. Some emails will look like a website in order to get you to enter personal information. Ebay never asks for personal information in an e-mail.

8. Misspellings and bad grammar

Fake emails may contain misspellings, incorrect grammar, missing words. Many Times these are used to trick the E-mail Filters

A quick review
If you receive an E-mail with a Link requesting you to click on the link and sign in to your E-bay account, Don't Do It!

If you receive an E-mail that looks like an Ebay Sign in Form, Don't Sign in!

If you are unsure if the e-mail is Real or fake forward it to spoof@ebay.com and request assistance.

If you absolutely must login to your Ebay account then I would highly recommend you do the Following. Close all open Browser sessions. Run a Spyware check on your computer You can get a free Spyware program here (http://ewguru.com/sware) then type in http://www.ebay.com/ directly into your Browser window and Login from the E-bay Web Page. Never click on a Login Link from Any E-Mail.

Optical fibers are designed for many different application scenarios. To understand the different applications, it is important to understand the properties of different fiber types.

Two major types of optical fibers exist for communication system: multimode fiber and single mode fiber. The difference between them is that multimode fiber can carry many modes of light rays while single mode fiber can only carry one mode of light ray. This is a big difference. This fact determines that multimode fiber can only be used in short distance link, usually within a few hundred meters, while single mode fiber is used on much longer, usually 40~120km, distance. Based on this fact, it is now easier to understand that multimode fiber is used in LAN network and video surveillance while single mode fiber is used in long distance telephony applications.

Another consequence of this difference is the information carrying capability difference between these two types of fibers. Single mode fiber can carry hundreds times of more information than multimode fiber.

Now let's examine the fiber types in detail.

Multimode fiber

Light ray travels in the fiber core at discrete angles within its acceptance cone. Multimode fiber has 50um or 62.5um diameter core, which is much larger than a 9um diameter single mode fiber core. Thus a large number of modes (light rays injected into the fiber at different angles) can be coupled into multimode fiber.

Now let's look at two light rays that travel along a multimode fiber. One light ray travels straight down the fiber core center which is the shortest path. A second light ray travels at a steep angle and bounces back and forth by the fiber core side wall (a phenomenon called total internal reflection) while traveling down the fiber length which is a longer path than the first light ray.

Since the second light ray travels a longer path than the first light ray, they arrive at the fiber end at separate time (the second light arrives later than the first). This disparity between arrival times of the different light rays is called dispersion. The consequence of this disparity is a muddied signal at the receiving end. In order to properly receive the signal, the signal must run at a slower rate and that is why multimode fiber's bandwidth is limited.

Single mode fiber

Single mode fiber, on the other hand, only accepts one light ray, which is the first light ray that travels straight down the fiber core center. So there is no arrival time disparity between different fiber modes which makes a cleaner signal at the receiving end. This is the reason why single mode fiber can run signals at much higher speed resulting in its much higher bandwidth.

Single mode fiber does have some disadvantages though. The smaller fiber core diameter makes it much harder to couple light into the fiber. This increases the manufacturing cost of many single mode fiber optic components such as isolator, attenuator, etc. The tolerances for single mode connectors, mechanical splices are also much more demanding.

One important variety of single mode fiber is polarization maintaining fiber, or also called PM fiber. PM fiber carries only one polarization (the light's electronic field direction) of the light. PM fiber's major applications include coherent communication system and electro-optic modulators which serves as a light transmitter in high speed fiber optic system.

This is the latest and most successful online money making technique in the market today wherein you neither require a website nor you need to promote affiliate links. You require only Google AdSense publisher code and need to submit content. It's a pure CPC site. The secret is to join AdSense Revenue sharing site and submit content.

AdSense revenue sharing means ad revenue from the forum or website can be shared between active members of this forum and the webmaster. It's a Win -Win situation. Just join a forum and create post. The forum uses Google AdSense to automatically serve relevant ads for the content that members create. Google pays AdSense publishers on a per click basis. Google is one of the leading CPC network in the industry and depending on the content and the Location, they pay from 20 cents to several dollars per click.

If a user has an AdSense account, they have the ability to credit their account with the ads served on threads in forum they start or participate in. In this case, 50% of the time, members ads are displayed and 50% of the time, webmasters ads are displayed. If some curious visitor visits the site and happens to click on the Ads served by Google for some information and if it's a genuine click then one gets paid for each and every click.

Is this allowed by Google?

Ans: There are tons of such sites on the internet flourishing since the day AdSense was launched and are still there. Again Google Terms and conditions does not mention anything about the same.

How do I start with the same? If you are not having Google AdSense publisher code then you need to create such an account (go to www.google.com/AdSense to sign up). For publishers having Google AdSense code, its just submitting the details at the time of joining the forum.

Where do I find such sites? One can go to the below site to start with:
