A fibre optic Christmas tree is an ideal way to add some festive cheer without having to worry about cleaning up fallen pine needles.

A fibre optic tree uses LED technology rather than traditional halogen. Most of the trees will have strands of plastic tubes surrounded by a reflective coating, which results in a striking display of lights. It works by simply plugging it into a socket, where you will see the ends of the branches light up or flicker between colours.

Fibre optic trees have their lights directly built into the tree, whereas pre-lit Christmas trees have LED lights hand-strung in between the branches. Fibre optic Christmas trees are much more energy efficient and economical, and these types of trees are safe to use around the whole family as they do not reach accelerated temperatures or use UV rays. The trees only give out light — not heat — which makes them one of the safest around.

Fibre optic trees are available in a range of shapes, colours and sizes, perfect for every type of home. Shop a selection of fibre optic Christmas trees here...

What is a Fiber-Optic Christmas Tree? (with picture)

G. Wiesen

A fiber-optic Christmas tree is a type of artificial decorative tree that is typically used indoors and meant for display around the celebration of Christmas. This type of tree can be made in a number of different ways, and may range from a plastic tree that uses optical fibers to provide lighting for the tree to a multitude of optical fibers arranged in the general shape of a tree to create an abstract impression of a tree using light. A fiber-optic Christmas tree typically requires less maintenance than other types of artificial trees, and may require less power as well.

A fiber-optic Christmas tree may be displayed in people's homes during the Christmas holiday.

There are many different ways in which a fiber-optic Christmas tree can be designed, and a number of different manufacturers that make them. In general, however, these trees are typically pre-lit using optical fibers, sometimes called fiber optics, to provide lighting for the tree. Optical fibers are thin cables that transmit light and other forms of energy signals throughout them, using different levels of reflection to allow the light to escape only where it is intended to do so. This allows a tree to be designed using optical fibers to light the tree in specific points or to provide overall lighting throughout the fibers.

One of the most common types of fiber-optic Christmas tree is an artificial tree with plastic limbs and “needles” that is pre-lit using optical fibers. This type of tree is generally similar in shape to an actual pine tree, with limbs and needles made from metal and plastic, from which other ornaments can be hung. Optical fibers are placed through the tree and designed to emit light only at their tips. One or more light sources is then used with the Christmas tree to illuminate the optical fibers, and the tip of each one provides lighting for the tree, fairly similar to traditional Christmas tree light bulbs.

The other common type of fiber-optic Christmas tree consists entirely, or almost entirely, of optical fibers and does not use metal or plastic to create artificial pine tree limbs. This type of tree usually has a base and central pillar, similar to the trunk of the tree, which can be illuminated as well and from which hundreds of optical fibers extend. These are designed to provide illumination throughout their length, rather than only at their tips, and are arranged to create the overall shape of a pine tree. The entire shape of the fiber-optic Christmas tree consists of light, and it can even be designed to change colors while illuminated.

How to provide Internet access in the most remote corners of the planet? Elon Musk sends 4,425 satellites into space, Google wants to use balloons to transmit the signal, and Facebook believes drone drones can do the job. While giant companies are competing to conquer the planet, fiber remains the main conductor to the world of high-speed Internet in megacities. We talked to Nikolai Dzhulai, Dom.ru expert, head of the network operation service, about what a fiber-optic cable consists of, why plastic loses to glass, and how optics help to monitor dolphins and oil.

Half of Dom.ru subscribers have three or more devices at home, and each user consumes an average of 50 GB per month at speeds up to 100 Mb/s. They watch HD videos, play tanks, broadcast online and go online from different gadgets. Fiber optic cables allow providing people with the Internet at maximum speed. The first optical Internet networks in Russia were built by ER-Telecom back in the early 2000s. Thanks to this technology, we became the fastest internet provider in the country according to Speedtest in 2017.

How a fiber optic cable works

Optical fibers are thin strands of quartz glass in which information is transmitted using light. Each strand is only 125 microns thick, slightly larger than a human hair. There are up to 96 such threads in the cable, each of which "floats" in a liquid - a hydrophobic gel. To ensure safety, they are covered with a polyethylene and plastic sheath, steel wire or metal armor.

Optics are buried in the ground, laid in sewers and even at the bottom of the sea. The cable, which is used underground or under water, is capable of withstanding a load of up to 8 tons. For comparison, an elephant weighs 5-6 tons. The glass from which the optics are made does not conduct electricity. Even if lightning strikes near the cable, the signal will not be interrupted and the Internet speed will not drop. At the same time, such a network does not produce any radiation and is safe for humans.

However, the optics are vulnerable. It can be damaged by frequent bends, due to which cracks form. When they appear, the light breaks out and the Internet connection is broken.

Repair with surgical precision

Last June, a tornado passed through Omsk. The wind tore off the roofs of houses, felled trees, cut off power lines. Fiber-optic networks also suffered - sagging and cable breaks appeared.

- Accidents are eliminated by teams of technicians whose work resembles a surgical one. They have their own scalpels, holders, nippers and degreasers - everything to get to the thin strands of optical fiber through dangling protective sheaths, - says Nikolai Dzhulai. — The cable is welded like a metal rod, heated up to 2000°C. Quartz begins to flow, and a small seam forms in place of the torn area.

The most common cause of damage is vandalism: a self-tapping screw screwed into the cable, hammered nails or an ordinary needle. To detect a problem area, special equipment is used - a reflectometer. The optical fiber is fired from a laser. The light flux flies along the glass filaments and in the place where there is damage, it is reflected and returned back. So technicians determine the location of the problem with an accuracy of 5 meters.

Dolphins and oil: where else is fiber used

Fiber optic technologies are used not only in Internet communications. One of the key uses of optics is acoustic observations. For example, cables are laid along oil and gas pipelines. This is how specialists detect sound vibrations, the appearance of which indicates the likelihood of an accident or unauthorized interference in the operation of the oil pipeline.

Biologists work with optical fiber to study the behavior of dolphins, whales and killer whales. The sensors act as sonars and pick up the sounds that animals use to communicate. In medicine, "optics" is used as a source of light. The thinness and flexibility of the cable helps to see what is happening inside the human body and adjust the treatment.

— In the future, we can expect a breakthrough in the development of optics, says Nikolay Dzhulai. — Many companies are already trying to reduce the cost of fiber optic production by using plastic and polymeric materials for the manufacture of filaments. But while the designs are losing to glass networks, they have lower speed performance and reflectivity inside the cable. For the next two decades, optical networks in cities will remain the main tool for accessing high-speed Internet.

Optical fiber communication principle | InterCamService

High-speed Internet connected people on different continents and allowed them to instantly exchange information, but how often do we think about the principles of its work? In today's material, trying to do without complicated terms, we find out how fiber works, and also how fiber optic communication is arranged and what are its advantages.

What is an optical fiber - briefly

An optical fiber is a thread made of a transparent material (glass or plastic), whose main property is the ability to carry light through internal reflection. An electrical signal transmitted through an optical fiber is converted into light and then back into an electrical signal. In a wide variety of communication networks, the use of fiber optic communication allows the transmission of audio, video and telemetry data over long distances at high speed.

By the way, for the first time an optical communication channel was used for data transmission back in 1997 in the USA, and even then the transmission rate was 6 Mbps.

The principle of fiber optic communication

As we mentioned above, in fiber optic strands, the signal is converted from electricity to light, and then - on the receiving side - back to an electrical signal. During signal conversion on the transmitter (source) side, if the data is analog, then a special encoder or converter transforms the data into digital pulses (a familiar digital signal of zeros and ones), and then into light. If the data is digital, then the signal is directly converted into light waves. In turn, already light waves are transmitted through a fiber optic cable from the source to the destination. And in the receiver, the light waves from the optical fiber are converted by the light detector into the corresponding digital signal. If the signal was originally digital, then this is the final stage of conversion, and if it is analog, another conversion will follow using a decoder.

The process of transmitting an electrical signal from one point to another by converting it into light is called fiber optic (or fiber optic) communication .

Advantages of fiber optic communication

Optical fiber has replaced copper as a transmission medium in wires not just because of the obvious advantages:
