Connector types

These elements are responsible for connecting the fiber lines to an element, whether it be a transmitter or a receiver. The types of connectors available are very varied, among which we can find the following:

• FC, which is used in data transmission and telecommunications.
• FDDI, is used for fiber optic networks.
• LC and MT-Array that are used in high data density transmissions.
• SC and SC-Duplex are used for data transmission.
• ST or BFOC is used in building networks and security systems.

• Light beam emitters: These devices are responsible for converting the electrical signal into a light signal, emitting the light beam that allows data transmission, these emitters can be of two types:

1. LEDs. They use a current of 50 to 100  mA , its speed is slow, it can only be used in multimode fibers, but its use is easy and its life time is very long, in addition to being economical.
2. Lasers. This type of emitter uses a current of 5 to 40  mA , they are very fast, it can be used with both types of fiber, singlemode and multimode, but on the contrary its use is difficult, its life time is long but less than of ledes and are also much more expensive.

• Electric light-current converters. This type of device converts light signals from fiber optics into electrical signals. They are limited to obtaining a current from the incident modulated light, this current is proportional to the received power, and therefore, to the waveform of the modulating signal.

It is based on the opposite phenomenon to recombination, that is, on the generation of electron-hole pairs from photons. The simplest type of detector corresponds to a PN semiconductor junction. The conditions that a photodetector must fulfill for its use in the field of communications are the following:

1. The reverse current (in the absence of light) must be very small, in order to detect very weak optical signals (high sensitivity).
2. Quick response (high bandwidth).
3. The noise level generated by the device itself must be minimal.

• There are two types of detectors: PIN photodiodes and APD avalanche detectors.

1. PIN detectors: Its name comes from the fact that they are made up of a PN junction and a new zone of intrinsic material (I) is inserted between that junction, which improves the efficiency of the detector. It is mainly used in systems that allow easy discrimination between possible light levels and over short distances.
2. APD Detectors: Avalanche photodiodes are photodetectors that show, by applying a high voltage in reverse, an internal effect of current gain (approximately 100), due to impact ionization (avalanche effect). The mechanism of these detectors is to launch an electron at high speed (with enough energy), against an atom so that it is capable of pulling off another electron fiber optics engineering jobs.

• These detectors can be classified into three types:

1. Silicon: they have a low noise level and a performance of up to 90% working in the first window. They require high supply voltage (200-300  V ).
2. Germanium: suitable for working with wavelengths between 1000 and 1300 nm and with a performance of 70%.

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 fiber splicing contractor jobs.

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. Multimode fiber 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.

how does fiber optic internet work

The fiber is fascinating on the grounds that it takes an old idea that is the control of light, is simply that, the controlled control of light. In the event that we return to history, the Egyptians themselves controlled the light by methods for mirrors to enlighten inside the mind blowing pyramids ... Forerunners of fiber optics?

Today the control of light is controlled inside a link, with unique terminations and on uncommon plates that make transmission conceivable and which I will detail all through this modest note what amount does a link installer make.

By finding in detail how fiber optics is formed, we will comprehend its points of interest and weaknesses, just as, we will have a worldwide vision of this medium. This model is about a link comprised of numerous parts, you need to comprehend that there are numerous kinds of links that adjust to various events (inside, outside, and so forth.), yet I accepting this as a source of perspective since you can find in detail what components can contain a link. This will be valuable in light of the fact that generally in the fiber optic link indexes, it is determined what they are made of, along these lines, knowing the parts and for what they work, we will have the option to pick the best link for what we are amassing.

Structure of an optical fiber

1-Dielectric focal component : this focal component that isn't accessible in a wide range of optical fiber, is a fiber that doesn't direct power (dielectric), which helps the consistency of the link, in addition to other things.

2-Moisture seepage string : its motivation is for the dampness to come out through it, leaving the remainder of the fibers liberated from dampness.

3-Fibers : this is the most significant piece of the link, since it is the medium through which the data is transmitted. It very well may be made of silicon (glass) or profoundly handled plastic. Here the physical wonders of reflection and refraction happen. The immaculateness of this material is the thing that has the effect to know whether it is a great idea to transmit or not. A straightforward contamination can redirect the light shaft, making it be lost or not to arrive at its goal. With respect to the assembling procedure, it is fascinating and there are numerous recordings and material on the system, however essentially the strands (microns wide) are gotten by presenting glass cylinders to outrageous warmth and through the trickling that happens when softening, it is they get every single one of them.

4-Loose Buffers : it is a little cylinder that covers the fiber and here and there contains a gel that fills a similar need, likewise making it a dull layer with the goal that the light beams don't dissipate out of the fiber.

5-Mylar tape : it is a flimsy polyester layer that numerous years back was utilized to transmit projects to PC, yet right now just satisfies the job of cover.

6-Flameproof tape : it is a spread that serves to shield the link from warmth and blazes.

7-Synthetic Kevlar strings: these strings help a ton to the consistency and assurance of the link, considering that Kevlar is an excellent fire retardant, notwithstanding supporting the extending of its strings.

8-Tear string : they are strings that help the consistency of the link how does fiber optic internet work. 

9-Sheath : the upper layer of the link that gives protection and consistency to the set that has inside.

Since we realize how a link is made up, how about we perceive how it functions. I won't detail the activity scientifically on the grounds that it isn't the real trick, I am just going to discuss the two marvels of optics that permit transmission and are the what tops off an already good thing. Likewise on the system there is a lot of data to extend your insight.

The two physical standards by which fiber works are Reflection and Refraction . They are to be faulted for doing this.

Which fiber optic cable is optimal for my installation?

Choosing a fiber optic cable can be a complicated process. Which fiber optic cable is optimal for my installation should consider many factors, including transmission speed, link attenuation, environment, cable types, fiber types, available equipment, optical connectors , splices, standards, and others.

However, the process can be simplified by following the manufacturer's and equipment instructions at the time of installation. These instructions usually provide enough information to select the appropriate fiber optic for easy installation.

Other considerations that must be taken into account when choosing the type of fiber cable for the installation should be the environment where it will be placed, the route through which our cable will pass, etc.

The first decision to make is whether to install a mono or multimode fiber optic system. Both are feasible but with different characteristics, necessary for depending on the type of installation.

Advantages of a single-mode fiber optic system

Singlemode fibers have the ability to transmit higher bandwidth and are ideal for long distance transmission links, and have lower attenuation than multimode fibers.

Singlemode fiber cables are cheaper than multimode cables and singlemode fibers can be found for optical wavelengths of 1310 and 1550 nm.

Advantages of a multimode fiber optic system

Multimode fiber is best suited for distances below 2 km and for wavelengths of 850 and 1310 nm. The bandwidth of a multimode fiber system is more dependent on its length.

Optical equipment for this type of fiber is generally cheaper than singlemode, however, multimode fiber optic cable is normally more expensive than singlemode fiber optic cable, but for short distances, savings in optical equipment can balance the cost.

62.5 / 125 um multimode fiber optic is the standard for LAN communications , as well as for Ethernet , Token Ring and FDDI networks careers in optics.

The conclusion can be drawn that single-mode fiber systems are generally used for long distances (above 2 km). Multimode fibers are intended for short-distance applications, as specified by optical equipment manufacturers.

The second decision to choose our fiber cable is the speed at which you will want to work. Below is the type of core of each of the optical fibers, the speed and the distance that each of them will support.
