Function process

In a fiber optic transmission system there is a transmitter that is in charge of transforming electromagnetic waves into optical or light energy, which is why it is considered the active component of this process. Once the light signal is transmitted by the tiny fibers, at a third end of the circuit there is a third component, called an optical detector or receiver, whose mission is to transform the light signal into electromagnetic energy, similar to the original signal. .

The basic transmission system is composed in this order of input signal, amplifier, light source, optical corrector, fiber optic line (first section), splice, optical fiber line (second section), optical corrector, receiver, amplifier and output signal.

In summary, it can be said that this communication process, the optical fiber works as a means of transporting the light signal, generated by the transmitter of LED'S (light emitting diodes) and laser fiber optic splicer salary .

Light emitting diodes and laser diodes are suitable sources for transmission via fiber optics, since their output can be rapidly controlled by means of bias current. In addition their small size, their luminosity, wavelength and the low voltage necessary to handle them are attractive features.

Devices implicit in this process

The main blocks of a fiber optic communication link are: transmitter, receiver and fiber guide. The transmitter consists of an analog or digital interface, a voltage to current converter, a light source, and a light source to fiber adapter.

The fiber guide is an ultra pure glass or plastic cable. The receiver includes a fiber-to-light detector connector device, a photo detector, a current-to-voltage converter, a voltage amplifier, and an analog or digital interface. In a fiber-optic transmitter, the light source can be modulated by an analog signal or digital.

Coupling impedances and limiting the amplitude of the signal or in digital pulses. The voltage-to-current converter serves as an electrical interface between the input circuits and the light source.

The light source can be an LED light emitting diode or an ILD laser injection diode, the amount of light emitted is proportional to the excitation current, therefore the voltage to current converter converts the input signal voltage into a current that is used to direct the light source. The source to fiber connection is a mechanical interface whose function is to couple the light source to the cable.

Fiber optics consists of a fiberglass or plastic core, a jacket, and a protective layer. The coupling device of the light fiber detector is also a mechanical coupler.

The light detector is generally a PIN diode or an APD ( avalanche photodiode ). Both convert light energy into current. Consequently, a current-to-voltage converter is required that transforms changes in detector current to changes in voltage in the output signal.

Fiber optic sensors

Optical fibers can be used as sensors to measure tension, temperature, pressure, and other parameters. The small size and the fact that no electric current flows through them gives it certain advantages over the electric sensor.

Optical fibers are used as hydrophones for earthquakes or sonar applications. Hydrophonic systems with more than 100 sensors have been developed using fiber optics. Hydrophones are used by the oil industry as well as the navies of some countries. The German company Sennheiser developed a microphone that worked with a laser and fiber optics.

Fiber optic sensors for temperature and pressure have been developed for oil wells. These sensors can work at higher temperatures than semiconductor sensors. Another use of fiber optics as a sensor is the optical gyroscope used by the Boeing 767 and the use in hydrogen microsensors.

illumination

Another use that we can give to fiber optics is to illuminate any space. Due to the advantages that this type of lighting represents in recent years, it has begun to be widely used.

Among the advantages of fiber lighting we can mention:

• Absence of electricity and heat: This is because the fiber only has the ability to transmit light beams, and the lamp that illuminates the fiber is not in direct contact with it.
• You can change the color of the lighting without having to change the lamp: This is because the fiber can transport the light beam of any color regardless of the color of the fiber.
• With a lamp you can make a wider illumination by means of fiber: This is because with a lamp you can illuminate several fibers and place them in different places fiber optics installer jobs.
• More uses of fiber optics
• It can be used as a waveguide in medical or industrial applications where a light beam needs to be guided to a target that is not in line of sight.
• Fiber optics can be used as a sensor to measure stresses, temperature, pressure as well as other parameters.
• Fiber patch cords can be used in conjunction with lenses to make long, thin viewing instruments called endoscopes. Endoscopes are used in medicine to visualize objects through a small hole. Industrial endoscopes are used for similar purposes, such as for inspecting the interior of turbines.
• Optical fibers have also been used for decorative uses including lighting, Christmas trees.
• Subscriber lines.
• Optical fibers are widely used in the field of lighting. For buildings where light can be collected on the roof and carried by fiber optics to any part of the building.
• It is also used to trick the sensory system of taxis causing the taximeter (some call it token) to not mark the actual cost of the trip.
• It is used as a component in the preparation of translucent concrete, an invention created by the Hungarian architect Ron Losonczi, which consists of a mixture of concrete and fiber optics forming a new material that offers the strength of the concrete but additionally, has the particularity of allowing the light wide.

What is fiber optics?

Fiber optics is a transmission medium commonly used in data networks; a very fine thread of transparent material, glass or plastic materials, through which pulses of light are sent that represent the data to be transmitted. The light source can be laser or LED.  

Fibers are widely used in telecommunications, since they allow large amounts of data to be sent over a long distance, with speeds similar to those of radio and higher than those of conventional cable. They are the transmission medium par excellence as they are immune to electromagnetic interference, they are also used for local networks, where it is necessary to take advantage of the optical fiber over other transmission media (source and more information: wikipedia ).

From 1985 to date, we have installed fiber optic cables throughout the national territory. The facilities began with the aim of linking the telephone exchanges as a result of the digitization of the metropolitan network; Today, all the cities of the Interior are united by a national fiber optic network, which constitutes the nucleus (or “backbone”) of the national transmission system.    

Starting in 2010, we began working on the most important and ambitious project in the history of the company: installing fiber optic cables in the customers' access to the network, gradually replacing copper cables, and allowing a width of Virtually unlimited band top fiber optic companies.

What type of fiber optic cable should you choose?

Fiber optic patch cord, often called fiber optic cable or bridge, is a fiber cable with various types of connector ends (LC, SC, MTRJ, ST). These allow the fiber optic cable to quickly connect to an optical switch or other telecommunication / computer device. Fiber cable is a key element for indoor use, such as in server rooms or data centers. It has excellent reliability, superior adaptability and enhanced security and has been the best choice for use where conventional copper cables do not go.

What are the types of fiber patch cord?

The fiber connection cable can be classified into different typologies and standards. For example, fiber mode, transmission mode, jacket type, connector type, and polishing type.

Fiber Optic Mode: Singlemode fiber (OS1, OS2) is yellow, while multimode fiber is orange (OM1, OM2) and sky blue (OM3, OM4). Singlemode (SMF) cable is 8–10 µm in diameter allowing only one mode of transmission, so it can carry signals at much higher speeds with less attenuation. In addition, it is ideal for high data transmission speeds or long distance. fiber optic technician jobs cable (MMF) is made of a larger diameter (50 µm and 62.5 µm) that can carry more than one mode of transmission. It is commonly used for short distances, from connecting the fiber cable or patch panel to the equipment.

fiber optics and how does it work?

WHAT IS FIBER OPTICS?

Fiber optics is a method of data transmission that consists of sending encoded information through a beam of light projected through a glass tube or pipe. It has its origins in the work of 19th-century scientists Jean-Daniel Colladon (a Swiss physicist who discovered that a continuous ray of light could shine through a water pipe through internal reflection) and John Tyndall (a physicist Irishman who formally demonstrated internal reflection to the Royal Society in London by illuminating the stream from a jug of water.)

AND HOW DO FIBER OPTIC CABLES WORK?

Fiber optic cables are made of very thin strands of glass or plastic, each of which is less than a tenth the thickness of a human hair. These threads are known as optical fibers, and each of them is capable of transmitting around 25,000 phone calls. Fiber optic cables typically range from a minimum of two to several hundred strands.

To ensure uninterrupted light transmission, the glass used in the manufacture of optical fibers must be very pure, so the core of a cable is usually made of silicon dioxide. Surrounding this core is a somewhat different layer or coating of glass, which is usually infused or "doped" with remnants of elements such as boron or germanium.

The core and cladding are covered with a plastic cladding and a Kevlar or metal fiber cladding, and the entire assembly is sealed against water and dirt by a protective outer layer.

A complete cable can only be a few centimeters in diameter, with a core of only five to ten millionths of a meter fiber optic installer salary

LIGHT BOUNCING AROUND

Transmission through fiber optics is achieved when the photons or light particles that form a beam hit the glass walls of a fiber optic at a very shallow angle (forty degrees or less), and are reflected back as if hitting a mirror. This is known as total internal reflection, and ensures that all transmitted light remains within the tube.

The physical structure of the cable contributes to this, since the doping applied to the coating reduces its refractive index with respect to that of the core (different reflection characteristics) and effectively limits the light beam to the core of the fiber.

Continuous lengths of cable up to 100 km (60 miles) are possible, with light bouncing off the walls and reflected in the mainstream at speeds of about two-thirds of the natural speed of light when empty (which is about 300,000 km or 186,000 miles per second).

That is why there is normally an equipment booth located 80 to 100 km (40 to 60 miles) away on long distance transmission lines, to augment or retransmit signals along the next section of cable.

How fiber optics works: advantages and disadvantages

Although it has been a reality for a long time and there are many people who use fiber optics on a daily basis, there is still a great lack of knowledge about how fiber optic works , its advantages or differences with ADSL . However, it is interesting to get to know it to be clear about what it offers and what can be required of it.

How counted fiber optics works easily

Sometimes technicalities confuse us when we try to understand concepts in a simplified way. We are not going to enter into terms only within the reach of those who are already experts to answer what is fiber optics. Fiber optics is a technology based on the controlled manipulation of light inside a cable. This has special terminations and is given on special plates that make the transmission of this possible fiber optics jobs.

Currently there are two types of fiber optics that we can use in our homes or businesses. These are  HFC or Hibrid Fiber Coaxial   and FTTH or hybrid coaxial fiber . What the operators market so that users have a fiber optic connection is a hybrid system between fiber optics and coaxial cable.

Currently, not all operators in the Spanish market offer the same type of fiber. Some offer one or the other type depending on which area . For this reason, it is important that if you plan to contract this service, you know its differences and be able to find out what type of optical fiber each marketer offers you. So you can make a better informed decision about who and what exactly to hire.

Main differences between HFC and FTTH fiber optics

FTTH fiber optic offers faster internet connection speed

However, it is not yet a mature technology or, at least, some experts point out. It is not necessary to know in detail how fiber optics works to understand that FTTH is faster but that it is not yet fully developed, although it can be used without problems and by the user with all the guarantees.

HFC networks do not stand the test of time well

HFC has more FTTH losses

Another issue that is important to consider and value is that HFC technology has more losses than FTTH . Generally this is due to the fact that the HFC does not go directly to the connection point of the home or company , and the copper cable that is between the connection and to the home or space in which it is going to be used, loses speed. In contrast, FTTH technology reaches the point of connection without any loss.

HFC's ease of installation, one of its biggest advantages

HFC is much easier to install than FTTH. This usually means lower cost and faster installation .

Fiber optic test or how to know if you get what you pay for

One of the doubts of many fiber optic users is if they are really receiving the speed they are paying for . The easiest way is through a fiber optic test, which is nothing more than an internet connection speed test .

You don't need to know how fiber optics works or have advanced technical knowledge about it to find out. There are many web portals that offer this type of test for free to users. These reliably measure the actual connection speed you are getting. The same happens if we speak from the field of wireless connections .

Although the ideal is to test it on more than one website and at different times, as not all detect the bottlenecks of the connection and could sometimes provide not totally reliable data. A multi - sampling will allow collating data and get a true picture of your connection speed fiber optic.

The HFC networks combine the fiber optic cable . The latter does not age well, suffers over time, needs revision , often patches or replacements, and may suffer falls. This with fiber does not occur, and it is important to know and take it into account.
