Big brains across the globe continue to unlock the secrets of the qubit and harness it for myriad uses — quantum hard drives, quantum computers, and even quantum refrigerators. The internet may be next in line to get quantum-ized now that researchers from Northwestern University found a way to route a photon qubit through an optical cable without losing any of its physical characteristics. A newly developed optical switch does the deed, which allows fiber-optic cables to share multiple users’ quantum info at once — making superfast all-optical quantum communication networks possible — and gets us closer to having our tweets and status updates whizzing to and fro at the speed of light.

Nyrius SW100 Digital Audio Optical Toslink 3 Input Selector Switch Compatible with Fiber Optic Cables, HDTV, Blu-ray DVD player, PCM, Dolby Digital, DTS, XBOX360, PS3

• 3 Toslink optical inputs and 1 Toslink output (bi-directional: can go in reverse direction)
• Allows you to connect up to three audio/video sources to one input
• Provides interference and distortion free signal transmission (0 db signal loss)
• PCM, Dolby Digital and DTS signals can be passed through this unit
• Does not require a power source

Get more hookup flexibility for your digital components with this versatile, high quality Digital Optical Selector Switch. This 3-Way Digital Optical Selector Switch lets you connect up to three different optical digital components to a component with only one optical digital input. The selector allows you to switch from one component to another just by turning the selector dial – no more disconnecting and connecting cables or moving equipment around. You can play any of the three components you connect and enjoy the output through your home theater system.

There are four optical digital jacks. The output jack connects to the main unit to which you would like to expand the number of optical jacks (normally a digital audio/video receiver/amplifier). The three input jacks connect to the source devices and allow you to output digital audio to your main unit. Switch easily between sources instead of disconnecting and reconnecting cables when needing to change inputs. The compact design wi

The term for a fiber optic cable that is currently not being used is called a dark fiber optic. Fiber optic cables that are functioning and have light signals travelling through them are called “lit” cables; hence if they are unused they are termed as “dark.”

On the other hand, since fibers are not used, it would not contain any light pulses inside, hence termed as “dark” or “unlit.”

The amount of dark fiber optic buried underground in the United States can span miles and miles.

The reason behind this is that, during the 1990s, telecommunications companies, electric companies and local municipalities laid down excessive amounts of unused fiber optic cables underground.

They considered the possibility of having to use more optic cables in the future, so they figured that they could refrain from the hassle of having to dig up the streets again and cause inconvenience just by packing extras in.

What is dark fiber?

However, this abundance has created benefits since there are so many extra fibers; the cost in turning the fibers lit is not as expensive as before.

Every day, more and more businesses are realizing that buying and creating their own dark fiber network is more economical as opposed to leasing the same amount of fibers.

Banks are primary consumers looking to using dark fiber to build their own networks. They have enormous traffic which is perfectly suited for the capabilities of the technology.

Apart from banks, colleges are also buying dark fiber optic in bulk numbers in order to build their own networks. Making dark fiber optic a great option for companies, whether public or private, in building and establishing a network.

Dark fiber optic has become a hot commodity for most companies looking to expand or establish their telecommunications network. There are several reasons why fiber optic technology is currently at the top of the game when it comes to telecommunications.

There are several great advantages that you can expect from fiber optic technology, making it a great solution for establishing a telecommunications system.

Here are some benefits that you can expect from utilizing dark fiber optic over copper wires.

Cost Effective

Higher Capacity

Being generally thinner than copper wires, you can fit in more fibers in just one bundle, thus, giving you a chance to accommodate more phone lines and to come through into your phone or cable box.

Less Interference

Using dark fiber optic cables will result in less degradation of the signal compared to regular wires. You will also notice that the phone conversations are clearer.

With fiber optic cables in place, there is hardly any degradation in the signal, unlike ones that you would find in a copper wire. As a result, the phone signal is much clearer.

This type of fiber is ideal if you are going to use it to transmit signals using computers and their networks. With light signals being sent out, the line is relatively clearer and more efficient.

With all these advantages, it is no surprise that more and more companies are opting to use dark fiber optic, turning them “lit” and utilizing it to strengthen and expand their businesses.

The telecommunications aspect of your company is in good hands with dark fiber optic technology in use.

From Mass Effect 2, “Customer Service. Sweeping up the store. Carefully explaining things to the technologically illiterate. It’s stunning how many people think light moves faster through expensive fiber optic cables than it does through cheap ones.” [via Consumerist]

As mankind evolves, they find more and more new stuff to work and play with. The internet was one of the major finds of humankind in the near past. Making new connections and letting everyone across the world share the same thing is the biggest plus point of internet. But for decades it remained somewhat of a hassle to work online because of its slow speeds. But with the introduction of fiber optic cables this has changed. It has become possible to work in very high speeds now. Download content within minutes if not seconds, and have conversations online as if you’re in the same room.

Some tend to compare fiber optic cables and wireless technology, to prove that wireless technology is faster. This is a common misunderstanding; fiber optic cables are more than a million times faster than a wireless connection. To give an idea of how fast fiber optic cables are it is believed that the entire US congress library can be downloaded to your computer provided you have space within a matter of minutes.

Getting connected through fiber optic cables is not as hard as you may think. A quick visit to your favorite search engine would bring you most of the details you need to make the right choice for you. There are websites dedicated to help you in this matter and you can also visit individual websites of companies that provide internet connections via fiber optic cables. Be it for home usage, gaming purposes or office uses these companies will be able to provide you with the technical help you need. Fiber optic cables will then be able to get you connected to the service of your desire.
