'Twins' Light Beam is Key to Fast Signals

The world of fiber optics is about to be revolutionized by twin light beams that mirror each other. This novel technology holds the key to better and faster signals. Once the interfering noise is cancelled there will be faster and speedier relay of information along the pipelines containing light signals.

The demand for fast signals has gone through the roof. If current trends continue pretty soon mankind will be up to its neck in fiber optics with online traffic causing logjams along these relay lines. However, according to the BBC News, a method has just been devised to solve this dilemma. It is called beam mirroring and it involves a similar procedure to the one used for noise cancellation in headphones.

The secret lies in producing a twin beam of light that actually has two beams-in-one that mirror each other. The function of these is to rebound from each other and continue on their journey through the cable. When one reaches its height the other one reaches its depth and vice versa. The chief defect in fiber optics so far has been a phenomenon called noise. When the power factor is increased in order to send the signals further this nuisance rears its ugly head causing many problems along the way.  The twin beam method allows a light signal to travel as much as four times the distance of an ordinary signal. A phase conjugation technique is used to reduce noise.
 
There is a demand for greater bandwidth as consumer volume and pressure increases. The growth is getting out of hand and the result is too much static on the telecommunication lines. This problem can now be solved by the twin beam mirroring technology. Instead of the faulty and slower system of a single beam that had to be relayed back and forth between the two ends, there is now a double beam that achieves the miraculous by saving up on time. It is an efficient technology alright. The strange thing is that no one thought of this before.

Furthermore, speed too is increased considerably thanks to this Godsend. Research regarding this matter is still in its infancy phase. The field of photonics and quantum mechanics both meld in this latest scientific analysis of fiber optics and light waves. The speed of light is so fast that it is virtually unbelievable. And yet the distances between stars and galaxies are measured in light years. A light year is the distance light travels in a year. Meanwhile, here on planet earth the effect is almost instantaneous since light takes less than a second to span the girth of the globe via fiber optics. This technology is also expected to create better methods of information storage, relay and retrieval in the near future.
