When talking about Fibre Optic technology most of us will only think these cables are source of high speed internet. It is true at glance as Fibre Optic has most of public applications for Ethernet. However, it is far beyond that. Numerous Industries are employing Fibre Optic technology for its unique features. From Medical to Aeronautics Fibre Optic has its great marks. In Medical, the fibre optic technology is used as a light pathway. Anoscopes, Amnioscopes and different microscopes, which facilitate research and diagnosis process, use these tiny glass threads for illumination purposes. Medical Imaging technologies, including X-Rays also use fibre optics.

Beside their application in Medical Imaging processes, fibre optics has stretched its roots in many other imaging applications. In such applications threads are aligned into the bundled form to guide image reach on the other terminal.

Fibre Optic threads also makes the operations smooth in industries which operates on heavy currents. Workspaces utilize fibre optics cables to minimize the effects of EMI and RFI. In these factories copper cables are rarely used since it can easily be effected with EMI and RFI.

Fibre Optic cables have also advantage to withstand the harsh physical environment. They can endure higher temperature, pressure and other factors without showing very little response. Considering their tough enough ability to face harshness they are used in oil and gas sectors for many purposes. Fibre cables used in oil and gas reserves to keep eye on vital information such as reserve level.

Fibre Optics have also exposed itself to many military and defence projects by many countries. All in all, fibre optics have stretched its limits from ground to air, sea and even space. There usage is undertaken according to need, using specific feature. For this reasons these tiny fibres of glass are designed, bundled and fused to acquire maximum output.

Rural areas are the places where it is hard to find internet connection, means you may disconnect with the whole world. However, there are only handy options available, still you can avail the high internet speed.  The modern technologies have made it easy to make internet accessible for everyone. We have looked around to find out best options for our readers, here are some of those:  DSL Internet: Most rural companies offer DSL Internet connection which could be enjoyed by using DSL modems. The speed depends upon the plan you chose. This is the best option in terms of high speed connection as DSL speed can goes upto 2 mpbs, furthermore DSL connections are flexible. Satellite Internet: Satellite Internet is another option in absence of DSL internet, some companies offers this connection for you. User will have to place a receiving dish at a specific position in his home to receive signals from satellite. However, you must consider some pros and corns of this option before adapting it since Satellite Internet can be difficult to access in bad weather conditions as well as it is expensive compare to DSL internet. This is worth considering if DSL connection is not available or Satellite connection can deliver higher speed. Mobile Broadband: Cellphones companies now offer access to internet. With this option user needs a USB broadband adapter or WIFI adapter. The broadband speed can be very impressive and higher, although they can be limited due to coverage area of the network. However, with the 4G networks you can enjoy high speed in rural areas or even in the remotest areas and it could be very pleasant experience. Dial-Up Internet: It is one of the oldest connection methods. The internet is provided through a tradition dial-tone modem and the option is very inexpensive. However, Dial-Up connection can be very slow, even at only 56 kbps. If you are looking for high speed, this must be the last option. One thing you must always consider is your need, how much will be your usage and importance. Always rely on the high speed internet when looking for high end tasks but you will have to pay a higher for such type of connections

Fiber Optics: A potential replacement of Copper cables

Fiber Optics has edged copper cables for communication needs. Fibre Optics is highly potential competitor of copper cables. However, we still find many of businesses worldwide still use copper wire system for data transmission. Throughout the article we’ll be looking at the benefits and how efficient is Fibre Optic technology.

The first and most worth considering phenomenon of Fiber Optics is its astonishing speed. Fibre Optics can transmit millions of pulses per second and the fibre optics cable has been practically found to transmitting 10 Gbps, which ensures greater bandwidth and big data transfer rate. Other than speed Fibre Optics also delivers high level of security, these cables are impossible to break into and leaked signal are not capable to decipher. The cables are also resistible to EM and RF, therefore noise and interface is prevented. Keeping in view this feature Fibre cables can be installed near the heavy machineries working area.

Fibre Optics Technology is also best to transfer data over hundreds and thousands of miles since the attenuation is very less, so the cables were rapidly adopted by businesses concerned to transfer data to large distances. Copper cables were needed frequently to boost up after short distances and also required to verify the transmitted message is true.

Fibre optics cables are lighter and more flexible compare to copper and can be installed on inconvenient places. Although fibre optic technology can be of high capital cost but still they are worth adopting. High Data transfer rate, security reliability and flexibility are all major factors contributing to characteristic of these cables. The latest trend has shifted many giant businesses to the fiber optics cables for various reasons.

Major breakthrough leads to double the Fiber Optics distance

Fiber Optics

Researchers at the University College London have discovered a new method to boost fiber optics signal distance. A study by Scientific Reports claimed that they data signal through fiber optics could be sent double the distance without errors in sub-marine cables via new technology. The new discovery is also being tested on fiber optics systems which are used in home and office networking. The technology is very beneficial as it can reduce the cost of long distance optical fiber communications by cutting their demand to be electronically boosted on their way. The new method is important for fiber cables which are deployed underground or deep in the oceans.

The technique is of dual importance, along with correcting the data signal it can also help to boost the useful capacity of fibers.

The UCL finding is used at the terminal of the connection, at the receiving end, without introducing any art within the link.

The research sponsored by EPSRC (Engineering and Physical Sciences Research Council) demonstrates the way to get rid of interactions that occurs between different optical channels within an optical cable. Study Author Dr. Robert Maher said, by eliminating the interference between the optical channels they were able to almost double the distance signal can be transmitted over without any error, from almost 3,200 Km to 5, 890 Km, which is record setting increase for this system architecture.

He explained the technique: The Challenge is to come up with a method to simultaneously capture a group of optical channels with a single receiver. “This allows us to undo the distortion by sending the data channels back on a virtual digital journey at the same time.” The discovery was carried out by using “16QAM super-channel” made of a set of frequencies which could be coded using phase, amplitude, phase and frequency to come up with a high-capacity optical signal.

Study author professor Polina Bayvel, which also belongs to UCL Electronic & Electrical Engineering showed her excitement to report such a great finding which can revolutionize the fiber optics communications. She said the latest technique can highly improve the efficiency of data transmission. Demand of internet is booming worldwide and this is a major global challenge researchers are facing. Coping the capacity limit of fiber cables is a major breakthrough towards overcoming the global demand of internet.

Facts about undersea networking cables

Networking Cables are generally compared with motherboard of computer, nano-wires spreading all across the board are similar to networking cables over the Earth. We just saw a smaller portion of internet cables, most of the cables which transfer data are placed in the depths of coldest ocean. We have collected some facts about the undersea networking cables.

Undersea installation is nerve-wrecking process

Ninety-nine percent of communication data is transmitted by the cables passing under the sea. Overall they make hundreds of thousands of miles, these cables are installed using special boats, knows as cables-layers. Installation of cables is very nerve-wrecking process since special care is taken to avoid any damage to natural habitat of marine species.

Variation is size with Depth

Size of networking cables becomes thinner with the increase in depth. The size difference is due to vulnerabilities. Usually cables at the 8,000 feet are less vulnerable. Though the cost of installing wires varies mile-to-mile.

Sharks biggest enemy of cables

Sharks are worst enemy to international communication. There are no final words why sharks bite undersea cables. Different reasons are proposed, including electromagnetic fields which could irritate the sharks or they are just curious towards these cables. However, the point is sharks are trying to eat our internet. To protect these cables companies, like Google, are shielding cables to avoid shark attacks.

Undersea Cables have threats like Underground Cables

Passing under the sea doesn’t mean communication cables are highly safe, they still have threat like on the ground. While the oceans are free of construction work, there are penalty of threats to undersea cables. Beside Shark attacks, boat anchors and natural disasters are serious fears to cables.

Spies Love Submarine Cables

Spies always focus to tap submarine cables to dig out secrets messages. During the peak of cold war, spies installed giant wiretap, the operation named IVY BELLS.
