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.

Key Principles Of Interior Design

November 3rd, 2009 No comments

In the interior design of any structure, there are many important factors that should be kept in mind. The following basic guidelines, if stuck to, will take care of a number of these factors. Each of these has an important role to play and it may be utilized in many ways depending on the type of space you are working on.

Unity: This concerns the idea that the whole home or any other structure is to be seen as one unit, separated or divided only by walls and staircases, and that there should be some amount of intrinsic consistency in the design of the unit as an overall entity. The overall theme must always be kept in mind.

Balance: This concerns the distribution of the visual weight in an area. Objects which have equivalent visual appeal should be put at different locations in the room to strike a balance along a predefined axis. Balance can be of three types. The most fundamental type is symmetrical balance, which is quite easy to attain. Asymmetrical is the second type of balance, which is very fashionable, but requires a lot of thought and originality. The third type of balance is radial, where you select an appropriate centre and position things relative to it.

Proportion: This is basically to do with the size and proportions of the objects. It is important that items in a room look good together in terms of their sizes. An absence of proportion will cause the room to give up its overall appeal as certain objects will be too visible, while others may get buried in the background.

Focus: A focus in interior design of a room is important for its appeal. Focal objects can be anything ranging from a furniture article to an attractive painting or some other artistic piece. The object should be such that it is significant in the overall design of the room and is able to grab the attention of the observer. It must stand out, but not look out of place.

Rhythm: This is again an essential aspect of good interior design. This implies that the room should have a flowing visual pattern and clear continuity. Arches, ornate designs on walls and ceilings, cautiously chosen paintings, repetition of shades and designs etc will help you attain a rhythm.

If adequate attention is given to these aspects, you can be certain that the interior designing exercise will be successful. It is dvisable to hire a good interior design professional who can handle all these aspects and also assist you with the details.
