What is fiber optics?

Fiber optics is a transmission medium regularly utilized in information organizes; a fine string of straightforward material, glass or plastic materials, through which beats of light are sent that speak to the information to be transmitted. The light source can be laser or LED.

Filaments are generally utilized in broadcast communications, since they permit a lot of information to be sent over a long separation, with speeds like those of radio and higher than those of ordinary link. They are the transmission medium second to none as they are resistant to electromagnetic obstruction, they are likewise utilized for neighborhood systems, where it is important to exploit the optical fiber over other transmission media (source and more data: wikipedia ).

From 1985 to date, we have introduced fiber optic links all through the national domain. The offices started with the point of connecting the phone trades because of the digitization of the metropolitan system; Today, all the urban areas of the Interior are joined by a national fiber optic system, which comprises the core (or "spine") of the national transmission framework.

Beginning in 2010, we started chipping away at the most significant and aggressive task throughout the entire existence of the organization: introducing fiber optic links in the clients' entrance to the system, step by step supplanting copper links, and permitting a width of Virtually boundless band employments in fiber optics network installer salary.

10 good practices for working with fiber optics

1. Cleaning. Cleaning tools for fiber optic installations

Possibly one of the most important aspects to take into account when working with fiber optics is cleaning.   The optical fiber is not affected by electromagnetic interference, but it is very sensitive to humidity and dirt.
A simple rub on the connector surface can even cause several dB of loss or attenuation in the system. There are different products on the market for proper cleaning of fiber connectors. Although the most common is still a paper gauze and isopropyl alcohol.

2. Order. Color codes

Related to the previous point (since they go hand in hand) we have the order. The complexity of a fiber cable increases as the number of fibers in the same cable increases (reaching 512 FO).
The fibers are organized in microtubes inside a cable, these microtubes follow a color code to know at all times what is the numerical relationship of the fibers. There are several standards and color codes, depending on the type of cable and its modularity.
Maintaining the correspondence of the fibers when making a splice requires a high degree of order and discipline.   Plans or designs should always be followed so as not to make mistakes.

3. Watertightness. Proper sealing of the cable entry.

The best way to ensure that the fiber (fusions and connectors) maintains its properties without introducing attenuations in the system, is tightness. Once the fusion has been carried out or they face two connectors, the most appropriate thing is not to interfere with or allow external agents to interfere with them.
The elements to protect the fiber, from interior boxes to exterior boxes must have a level of tightness in accordance with the environmental exposure they may suffer. The IP XY (internal protection) standard defines different levels of protection against ingress of (X) dust and (Y) liquids.
One of the weakest parts against sealing, is usually the entry of cables in the boxes and the closure of the box itself.  You have to be extremely careful and follow the manufacturer's advice so that these parts are well sealed.

4. How to measure correctly. Gauges and measurement type, potentiometers / reflectometers

Measurement of a fiber optic system is a complex task and can be done in several ways and with different tools. A system must meet minimum and maximum power losses.
Potentiometers can be used to check the attenuation of the system, for this a source or transmitter inserts a light beam at a certain power at the beginning and at the end a power meter is placed that measures the incoming light beam power, from this way the difference between the input and output values ​​is calculated.
Reflectometers introduce a light beam, but in this case they analyze the resulting signal that reflects or bounces along the system at the same point in the system. By means of reflectometry, the signals can be analyzed graphically, taking at a glance the losses that appear in it.

5. Accommodating the fibers. Bending radii, fiber types G652 G657

Once the fusion is made, the excess fiber optic remains unprotected / without cover (bare with a thickness of 900 microns) with a length of approximately 1 meter. This surplus must be accommodated correctly, in the trays where the fusions are housed, for this the fiber is rolled up and stored.
It is important to know that the fiber cannot bend excessively, since losses would appear.   There are different types of fiber and each one allows a minimum bend radius.

6. Cable Retention, Aramid / FRP Core

The fiber optic cable construction has a reinforcing element used to protect it from jerks once it is installed in a box. This reinforcement is inside the cable and separated from the tubes where the fibers are housed. It is used to fix the end of the cable to the box, in this way in case of pulling the cable from the outside, the cable does not come off and the fusions and / or connections are protected. For each cable and box a number of Newton meters is determined that must withstand the traction.
Two of the most commonly used reinforcing elements are aramid yarns, a polyamide with highly resistant properties and the FRP core, it is a reinforced fiberglass.

7. Risk prevention. Work at height.

This aspect of work is common with other sectors, but no less important.   The regulations for the protection and prevention of occupational hazards must always be followed.
There are some specific aspects to take into account when working with fiber, correct handling of the fibers; If they can jump into the eyes or get into the hands (wear safety glasses and gloves), the light from a fiber optic produced by the fiber light generators can seriously damage the eye, even if the light is invisible.

8. Specific and quality tools. Fuser and cutter.

Working with fiber optics requires knowledge of specific tools that are not used in other fields , the most prominent being the fusion splicer and cutter. The fusion splicer works with micron precision to join two fiber optic cores, for this purpose, by means of two electrodes, they fuse the ends of the fibers.
To achieve a correct fusion it is very important that the ends of the fibers are clean cuts, without edges or burrs. To achieve this precision in the cut, a special cutter is needed, which fixes the fiber and passes a high precision circular knife to leave the fibers ready for fusion.

9. Breakdowns. How to detect them

A fiber optic communications system is relatively more stable and secure against breakdowns, but like any system accidents and breakdowns can occur. The most common are cuts or lack of continuity, but losses can also appear due to twisting of the cable or bending of the fiber.
The best tool for detecting faults is the reflectometer, since it can locate with great precision the distance at which the cut or loss is.

10. Losses, insertion and return. Attenuators

There are several types of losses in a fiber optic installation, the most common or the ones that are given the most attention are insertion loss and return loss.
Insertion losses are those that occur when a new element is added to the system, it can be a fusion, connectors, splitter, etc. These elements reduce the power of the signal, and are calculated as the difference in power between the input of the element and its output.
Return losses are measured as the difference in signal strength between the input and the reflection or bounce of light caused by the element. The greater this difference means that the lower the reflection or rebound, that is, the better the element will be how does fiber optic work.

What is 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 jobs

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.

Fiber optic network: how does it work?

At Alpha Telecom Solutions we are experts in the design and installation of fiber optic telecommunications networks for campsites , hotels or other tourist complexes . And betting on fiber optics, we explain exactly how the fiber optic network works to better understand the advantages that this system can offer you fiber optic jobs near me.

What is the fiber optic network?

The fiber optic network is currently the best way to transmit information, being able to transmit up to 1G per second . To achieve such speeds, the fiber interprets light as information , and uses its speed for its transmission.

What is its structure?

To understand how it really works, it is important to know how fiber optic cables are composed .
The cables are mainly made up of two elements :
  • Optical core : formed by the set of glass or plastic filaments , with a diameter of 1/8 of a millimeter known as optical fibers. Each of these can contain hundreds of strands of fibers.
  • Protection elements : Armor, covers, etc. Layered superimposed around the optical nucleus, protecting the optical nucleus from the environment.

How does the fiber optic network work?

Controlled pulses of light are transmitted through fiber optic cables This light is transmitted through LEDs or lasers, and travels throughout the fiber until it reaches its destination.
It is in the light where the information or data is found in the form of bits that are transmitted throughout the network.
In order to bring information through light, a principle of physics is used that reveals that light can travel through glass ; light particles or photons hit the glass walls of a fiber and are reflected as if hitting a mirror.
This principle, known as light reflection , allows all transmitted light to remain inside the cable until it reaches its destination.

Fiber optics can offer us great benefits over data transmission speed , file quality or network security, among many others. Therefore, installing a fiber optic network in your camping or hotel can be a before and after for your business. If you want to know more about the advantages that a fiber optic network can offer, contact us. At Alpha Telecom Solutions we are experts in the design and installation of fiber networks for hotels or campsites.

Tips for Help Desk Solutions

1. Map your processes
Before shopping, organizations should develop procedures for managing incidents, change requests, problems, and creating flow charts. "This way you know what to do, who does what, and how the process flows," says Steve Villalpando, director of IT governance for the Virginia Farm Bureau Federation. "Once you have defined one, the mapping process is repeated by everyone and you can choose a tool that supports it."
2. Don't go too fast
Before proceeding with implementation, take the time to write down your expectations of a help desk tool and what you want to achieve. "There are a lot of little things that need to be set up and if you do something wrong at first, it can affect you in the future," says Bob Kay, COO of Vistex.
3. Take a balanced approach
Organizations must invest heavily in their people, processes, and technology. "If I have beginners in a helping desk, no matter what tools I bring, they will continue to do the job as newbies," says Jeffrey M. Brooks, research director at Gartner. “Many organizations put a lot of focus on software as an integral component of the help desk, when it really isn't. Technology is just a tool, but not the solution for everything helpdesk jobs near me. ”
