Concepts Of Fiber Optics Transmission

November 3rd, 2009 No comments

Fiber optics is basically a technology that uses thin and hollow glass threads in order to transmit data. Fiber optic cable is one that consists of large number of cables and each single cable is capable of transmitting large amount of messages. Fiber optics is the most advanced technology that is used to transmit data from one place to another.

Data is modulated with light and is then transmitted. The property of light that is commonly known as total internal reflection is its basic principle. When a beam of light passes from denser medium to a less dense medium, reflection occurs and light ray moves away from normal. Therefore if the angle of incidence is changed to such an extent that light ray bends 90 degrees to the normal. This angle is known as critical angle. The angle of incidence beyond which critical angle increases is known as total internal reflection. Fiber optics is mainly based on this phenomenon.

Several advantages of fiber optics communication are as follows: Since today is an age of digital electronics, fiber optics provide you the facility to transmit your data digitally. Moreover the distortion is almost negligible.

Telephone lines that comes to your home are also made up of fiber cables because the signal remains undistorted at the receiver’s end. The signal does not attenuate, thus possessing a complete signal strength. Electromagnetic interference and radio frequency interference do not degrade its performance. The data carrying capacity of optical fibers is also more than the traditional systems.

Optical fibers are least affected by temperature variations and the bit error rate is also less as compared to copper wires. So these are secure and has increased data transmission rates and reduced the costs.

Flexibility is also an advantageous feature of this technique which makes it easy for transportation. Other than this, optical fibers posses light weight that makes them portable as compared to conventional copper wires and occupies very less space. Besides this, they are very beautiful so can be used for decorating homes. These are even used in digital cameras these days.

Fiber optic cables are light weight and hence are very handy. Comparatively they need less space at the time of installation. Cost of manufacturing optic fiber cables is not much since they are made up of sand and silica.

All these qualities make fiber optics the highest speed communication system. Advantages outlined above supports its use in almost every field. They are mainly applicable in telecommunications and computer networks. They are also used for medicinal purposes for inspecting the inside of a body. Plumbers are these days using this technology for fixing the damaged sewer lines.

Home Lighting Arrangements

October 22nd, 2009 No comments

Lighting plays a very important role in the overall look and feel of an area. Even if all the other things in a room are just perfect but there is no good lighting, all your efforts would be wasted as no one would be able to notice anything. Therefore, a good home lighting plan is very necessary which should be functional and aesthetically pleasing at the same time.

Bedroom is a place where you relax, sleep and carry other important activities also. So, you need to have adequate lighting for each task. Like for doing any work, you would require bright lighting. A good option is florescent lights. They emit light very similar to natural light and are energy efficient lights. Compact florescent light bulbs are the latest lighting fixtures and are available in plenty of designs.

Many people are into a habit of reading before going to sleep. For this, you can have a night lamp on the side table. For the dressing table, you should have focused light placed just above it so that the light produced is shadow free and you can comfortably dress up your self.

For lighting up a living room, the first thing to consider is the size of the room. If it is large sized room with a lot of open space, then you should go for soft lights and highlight areas you want to draw special attention to.

In case your living room area is not that huge, then you should always go for bright lights. A room which is brightly lit appears to be larger. Up lights i.e. lights facing the ceiling are good to use in these rooms as they make the room look higher and more spacious.

If you like to decorate your home with artworks or paintings etc, then you should place them in areas where they can be noticed. To draw attention to such special pieces, you can use lights to accentuate them. Lights make them look really amazing. Also, keep the lights around them dim so that they are noticed separately.

For kid’s room, you can get bright colored lamps with fancy shades. Ensure that the switch is near the bed so that children can use it comfortably.

For hobby areas, the lights should be chosen according to the exact needs and requirements. They should be practical. Like for painting, reading etc. one would require direct shadow free lighting. Also, the lighting fixtures chosen should be such that they match the over all room design.
