A striking green and silver laser multi-coloured LED fibre optic Xmas tree. 2011 sees the advent of a new revolution in the world of Fibre Optic Christmas Trees. In the past, these artificial Xmas trees had to rely on bulky base pots to house the halogen bulb and revolving, multi-coloured wheel. All the fibre optic ends were housed at the base of the tree, so by shining the light through the colour changing wheel to the fibre optic ends, light passed through the optics and exited through the other end, dispersed all over the tree. This gave the beautiful effect of colours and motion. Next came the LED light revolution and with extra cables and sockets, it allowed the marriage of optic fibres and LED lights on the same Christmas Tree, but, again, the bulky pot, extra wires and a bulb to blow! But times have changed and technology has leapt forward. Gone is the pot (replaced by a conventional 3 or 4 pointed stand, thus saving room). Gone is the hot, potentially hazardous halogen bulb (replaced by cool, long-lasting LED bulbs with 35000+ hour lifespan). And gone is the bulky storage box due to the dimensions of the housing pot. The key now is a simple round “socket”. Much like an outdoor, waterproof socket to look at! This houses the LED, morphing bulbs with a host of colour changes and multi-actions, and a reflector. It then plugs over the fibre optic “socket” (which is a single socket on the smaller Xmas trees or in 2 halves as the tree gets bigger and in sections). A …

I’m Alex Villarreal with the VOA Special English Technology Report, from voaspecialenglish.com | http In January, a five-day Internet shutdown in Egypt failed to stop the protests that forced President Hosni Mubarak to resign. But it raised a technical question. Just how were Egyptian officials able to shut down Internet service in their country?Craig Labovitz is chief scientist at Arbor Networks, an Internet security company in the American state of Michigan. Mr. Labovitz says the Internet is not as indestructible as people might think. He says there are points where the flow of computer traffic can be restricted. Mr. Labovitz says his researchers tracked the Internet shutdown in Egypt as it was being carried out. He explains that in Egypt, Internet users connect to the outside world through a small number of providers with international links. He said there are a hundred or more providers within the country — domestic providers. But there really are only four providers that have links to the external world. And there are an even smaller number of data centers where the fiber optics cross Egypt. So only a handful of machines need to be shut down to have this kind of disruption.News reports suggested that the fiber optic links for those networks are all housed in the same building. Could a similar Internet shutdown take place in the United States? Craig Labovitz says that is less of a possibility because of a larger number of Internet providers and data centers. Still …

Seemless Transitions From Serial Toward USB, Ethernet And Even Fiber Optics

Article by Petr Alberts

Computer Technology Woes and SolutionsBoth USB and RS232 are serial ports and they do have pretty much the same function. They are both used to connect various pieces of equipment to our computer. Back in the day when USB was fairly new to the computer world, every computer had that D-shaped port on the back, the RS232 port. So, frankly, there was no need for a converter cable from one port to the other.Unfortunately time passes and trends in our computer technology tend to go along with the changes that life goes through as well. Nowadays, when customers purchase a brand spanking new computer, it will surely come with a lot of USB ports but most likely won’t have an RS232 port anywhere.Many people have seen the versatility of the USB port. People think of it as a plug that can be used for almost any device, which is really the true meaning behind the name of the port being called “universal.”The rather unfortunate discomfort for folks who still use devices that uses the old RS232 port or cable is that they can’t plug their device to the new computer they just bought. Talk about a bad out of the box experience. This can be a real pain for those who own a GPS and a new computer without the serial port on the back that has 9-pins on it. Fortunately, nowadays, we do have a USB to RS232 converter cable.FeaturesThis new converter cable has a lot of great features that users can benefit from. Of course it allows users to connect their GPS to the new computer but there’s more to it than what we normally would expect. For instance, this converter cable is usually designed to be heavily shielded. This feature will help eliminate any form of data loss.This converter cable is actually more than just a cable. It is in fact a piece of electronics since it has a prolific chip adapter. Take note that it takes more than just to solder both USB and RS232 ports onto a cable and voila. This cable converts signals and provides connectivity between a computer and any device that has an RS232 connection such as serial printers, POS, some pocket PC models, some models of digital cameras, PDS, modems, and ISDN TAs.With the electronics that come along with this converter cable, anyone’s serial port expansion problems can be easily solved. These converter cables have a lot of industrial applications. It is also quite usable for remote access as well. Any application that would require one to use a high speed and low com port will find this cable pretty useful.ReminderLife isn’t as simple as it seems and that also is true in our computer technologically boosted world. To think that a USB to RS232 converter cable alone will magically solve all serial expansion problems is equivalent to getting blind sided. Remember that everyone is trying to solve both a hardware issue and a software issue as well.People may have an adapter cable that fits but they will surely require a piece of software that works. Take note that some manufacturers do not support certain operating systems, such as Windows Vista for instance. Before you purchase one of these converter cables, make sure to read the documentation that comes with it. Make sure that the software that comes with this piece of hardware supports whatever it is installed on the computer at home.

Know It Before, The Advantage and Disadvantage From the Fiber Optic Wires

Article by Alvaro Butler

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.

Get the Best From Your Broadband

Article by Daniel Collins

If you are thinking about getting broadband in your home, or are considering switching provider, then doing a spot of research can stand you in good stead and save you money in the long term. There are several handy things you can do in and around your home to maximise the broadband service you receive. If you think your broadband service is slowing down then check the speed of your existing subscription. Speeds of around 2mb were common when broadband was first introduced but current speeds rest anywhere between 8mb and 20mb and even beyond if you want a super-fast service. Fibre optic broadband cabling is being introduced in the United Kingdom and this will give users speeds of up to 100mb so look out for this if connection speed is top of your priority list.The quality of the cabling you use, as well as your modem, will affect the speed of your internet connection. You can buy high capacity cables and modems, both online or on the high street, and see if this makes a difference.Using a quality Microfilter, which splits your phone line and broadband connection, can work wonders too.When it comes to your router you should make sure it is password protected so anyone in close vicinity cannot access the internet through your network. If no one lives in close vicinity to your house this may not be a top priority but it is a worthwhile task, especially from a security point of view. Encrypting your router is usually a straightforward affair and it is best to simply follow your manufacturer’s guidelines. Set up a password to protect your network and make sure no-one else is benefiting from the connection you are paying for as this would slow down the speed you receive in your home.It is also worth remembering that there are specific times of the day when the internet is being used by more people overall and this can lead to slower speeds. If you have any large files to download then it might be worth waiting until an off-peak time, such as late at night, to download them.If you are thinking about changing your broadband provider, or are getting broadband for the first time, remember you can often subscribe via a service you already receive. For example, Sky television customers can benefit from special deals and offers on home broadband.If you sign-up for Sky television then you may be able to benefit from free broadband as well as free evening and weekend calls to landlines in the United Kingdom. Offers like this are fairly common so it pays to shop around before making your final decision.
