And as you may also know, in this house of what we are also good fiber, that’s why run to take a look at the best fiber offers. Fly!

Once we understand fiber optics and how it works, it is normal for us to be assailed by doubts about the different types that exist. In summary, they are classified in this way:

• Optical fiber depending on the type of cable
• Optical fiber depends on the wiring termination.
• The optical fiber according to its mode of transmission.

Optical Fiber Depending on The Type of Cable

Single-mode fiber optic cable: its diameter is between 8 and 10 microns (a very small unit, one-thousandth of a millimeter) that gives rise to a single mode of transmission. This means it can transmit signals over a greater distance if we compare it with a multimode cable. Thus, you can reach a space 50 times greater with a single-mode line. 

And what are its disadvantages, then? Its price, on the other hand, maybe higher. Generally, this type of cable is used to send data in multi-frequency.

Multimode fiber optic cable: it is normal that its diameter is greater than that of a single-mode line and has between 50 and 62.5 microns. This makes it possible for you to transmit in broadband at high speeds. It is normally used for shorter distances. As for its price, it is cheaper. This multimode cable classification also highlights 5 types: OM1, OM2, OM3, OM4 and OM5.

As you can see, there are differences between single-mode and multimode fiber that you should consider, but stop there! We still have one more option on this list:

POF or Plastic Optical Fiber: This option is ideal for sites where there are coverage issues. One of its main features is that it is made of plastic (which contributes to its durability) and is very flexible. In addition, it is positioned as especially affordable in terms of its price.

The Optical Fiber, According To The Wiring Termination.

• FTTH: the origin of its name comes from the English ( fiber to the home ) and means thread to the house. It is the most common type of connection, direct and reliable since all its cables are fiber optic. It connects homes, offices or the like with the operator’s switchboard and is also known as shared fiber.
• FTTN: In fiber to the node (which means thread to the node), the connection is directed from the main hub to an intermediate node and, from there, through a coaxial or copper cable, it connects with the place from where it is connected. You have contracted the service.
• FTTA: is the acronym for fiber to the antenna. Directs the fiber optic connection towards the telephone antennas to provide high speed. It is ideal for covering a higher mobile bandwidth for smartphones and tablets.
• FTTB: fiber to the building or thread to the building has the particularity that the fiber optic connection reaches a building through a coaxial or copper cable. Once there, it is distributed to each home or room (depending on the type of building in question).

The Optical Fiber, According To Its Mode of Transmission.

Simplex Fiber Optic: In this type, signals flow in only one direction, making it an excellent option for sending information that floats over long distances and unidirectionally. It consists of a connector at each end (the transmitter is in one, and the receiver is in the other; these cannot be interchanged).
Duplex fiber optic: Here, the signals circulate bidirectionally, unlike what happens with simplex fiber optics. In this type of fiber, there is the half-duplex style (it sends passwords in both directions but in a single order simultaneously) and the full-duplex (the signals are transmitted simultaneously in two different directions).

So, What Type of Fiber Optics Should You Choose?

After this complete review, surely you want us to give you the magic key to choosing the best type of fiber optic. The quick answer is that it depends on the needs and characteristics of the site where you want to contract the services. However, we leave you some criteria to take into account so that you make the best decision:

• Look at the type of building (is this your home? an office? or a large company?).
• Look at your budget ( the price you will pay can also help you decide on one option or another).
• Look at the data flow you need (do you want the information to travel long distances? One way? Bidirectionally, and simultaneously?).

Now that you know the types of fiber optics, the decision is in your hands. Still, if you want to go even further because your curiosity is piqued, we leave you some interesting information about symmetrical fiber optics.

Their speed is considerable: generally, several tens of Mbps. For this reason, the deployment of fiber optic and coaxial cable networks carried out in recent years (for example, by the network system Vodafone) brings companies closer to the possibility of having the advantages of these high-speed connections.

The fact that the 100 Mbps threshold is exceeded considerably widens the range of options. This means that we can have other types of services through our connected devices and the usual internet access. But what are the differences between fiber and cable? Which is better of the two? What possibilities do one and the other offer us?

Fiber Optics – Without a Doubt, The System To Highlight

There is no doubt that fiber optic connections are a transmission medium with excellent characteristics. The high capacity to transmit data and the low attenuation stand out among them. The latter allows linking many kilometers of fiber optic cables with hardly any signal loss.

The fact that they transport photons of light and not an electric current favors that they do not suffer any alteration due to possible electromagnetic interference.

We must know that these interferences seriously affect the usual systems based on copper cable.

Let’s Know What Fiber Optics Is

It is a thread made of a transparent material, usually plastic, through which light pulses are sent. These light pulses represent and contain the binary data to be transmitted. This fact is based on a theoretical principle known as Snell’s Law. Said law regarding the propagation of light along the optical fiber explains the refraction phenomena that light produces in different ways.

Whether it is one type of medium or another, and with its different physical properties, the value and behavior of this refraction of light will be different in each case.

Optical Fiber Transmission Speed

The possibilities of fiber optic transmission speed are very high since it works with frequencies of the THz order. This means values ​​higher than 100, 200 or 300 Mbps. 

Bandwidth is extensive, and this is one of the main differences between fiber and cable. In this way, channels are offered symmetric speeds for uploading and downloading.

Security In Communications Is One Of The Critical Differences Between Fiber And Cable.

In the case of fiber, transmissions cannot be intercepted by an illegitimate user without being detected. However, in systems based on copper cable, there is the possibility of making splices; these types of actions may not be detected by either the receiver or the transmitter.

Characteristics of Coaxial Cable

Coaxial cables carry data using electrical signals, one of the fundamental differences between fiber and cable. These coaxial cables are susceptible to electromagnetic interference.

These cables are much more prone to signal attenuation caused by cable losses when the cable is of considerable length. To ensure that this signal does not weaken, it is necessary to place signal amplifiers distributed in each section.

Coaxial Cable is Often the Final Part of The Network Installation.

This means that this coaxial cable is installed in the last section of the network. These networks are called HFC (Hybrid Fiber Coaxial) type, and sometimes they are sold as a pure fiber optic installation, but they are not.

In a pure fiber-optic network, this reaches entirely within the company. The fiber is connected to an ONT (Optical Network Terminal), and then it is responsible for transforming the photons into electricity.

Another difference between fiber and cable is that the fiber only reaches a certain point in a typical HFC scheme. Later, it is deployed to each company through coaxial cable. For this reason, the total speed of the network would be distributed among all the companies that share that part of the network.

Summary And Conclusions of The Differences Between Fiber and Cable

Transmission speed is also a determining factor in the differences between fiber and cable, with fiber optics being a clear winner.

Today when it comes time to contract the Internet for companies, the great unknown that still raises many headaches arises the differences between ADSL and Fiber Optic.

In this article, we will solve all your doubts about it so that you can make the best decision according to your needs: Fiber Optic or ADSL?

Differences Between ADSL And Fiber Optics

What advantages does Fiber Optics offer over ADSL? What are the differences and what advantages do they offer us? We’ll tell you then.

The Big Difference Between ADSL And Fiber Optic – Speed

Before starting to detail and list the differences between these two types of connectivity, it should be noted that the main difference has to do with speed.

ADSL is slower, it covers lower speeds than Fiber, but it has more network coverage. That is, it reaches more homes.

Fiber can reach 600 symmetric megabytes, while ADSL barely exceeds 20 Mb.

In addition, if you contract Fiber Optic, you will be able to connect several devices simultaneously and not notice a drop in speed. On the other hand, with ADSL, you can have a lower speed than the one contracted.

Advantages and Disadvantages of Fiber Optic

In short, fiber optics has become the best Internet solution for companies.

This is the latest and fastest solution, but it is still under development. Its only handicap has to do with coverage since there are still many corners it does not reach.

Although it will not be a problem for a long time, since companies are investing to increase the deployment of Fiber Optic and today, there are many other ways to get a good connection in isolated areas.

On the other hand, with Fiber Optic, the speed you contract is the one you receive, and the price depends on the speed you want to contract.

In addition, it guarantees more excellent stability, avoids annoying network drops for users, is immune to magnetic interference and has a higher level of security than ADSL, thanks to its FTTH ( Fiber To The Home ) installation.

Fiber Optics And Its Origins

The transmission media used to communicate signals from one point to another are copper cables, coaxial cables, waveguides, and radio links. All these means have their advantages and disadvantages.

Since the 1980s, an alternative medium to all of them called fiber optics has been developed, constituting the new frontier in telecommunications transmission. The ability to take advantage of all the capacity that light possesses to transmit information over long distances has been possible thanks to the improvement of the laser and the manufacture of very thin glass threads (less than the thickness of a human hair). Called “optic fiber.” Inside these fiber-optic threads, a modulated light beam is used to transport information based on the principle of total internal reflection and Snell’s law.

Parts That Make Up The Optical Fiber

The optical fiber is composed of the following parts:

• The core or central part, made of fused silica glass (SiO2) and optically transparent, is where the light beam is guided. Its maximum diameter is 62.5 µm (according to the ANSI standard)

• The cladding covers the core and prevents light from leaving the body. It is also made of glass but with a lower refractive index. Its diameter is 125 µm for all types of fiber.

• Primary coating (primary buffer). It consists of plastic with a width of 250 µm that surrounds the previous fiber components to protect them since they are too fragile to be handled directly and increase their mechanical resistance.

• Other common additional elements include secondary cladding, structural and reinforcing elements, outer sheath, and protection against water.

Once this brief introduction has been made, we can understand the different types of an optical fiber according to a certain characteristic.

What Types of Fiber Optics Are There?

Depending on the characteristic we focus on, we can have different types of Fiber Optic, which makes them more suitable for use.

Types of Fiber Optic According To The Cable Termination

• FTTH. It comes from the acronym for Fiber-to-the-home. The fiber optic par excellence connects the operator’s switchboard with our home or office. It is the most direct, fastest (sometimes above the contracted speed), reliable and secure way to connect to the Internet. They can reach speeds between 300 Mbps and 1 Gbps. This fiber is also known as shared fiber and is the most common and most used.
• FTTN. Fiber-to-the-node, the fiber optic cable connection runs from the carrier’s main hub to an intermediate node. It is linked to the point where the service has been contracted employing copper or coaxial cable from that intermediate node.
• FTTA. Fiber-to-the-antenna takes the fiber optic connection to the telephone antennas to provide high speed. It covers the need for higher mobile bandwidth for smartphones and tablets.
• FTTB. Fiber to the Building, the fiber optic connection reaches the Building. From there, it is distributed through copper or coaxial cable to each house or room, depending on the type of Building (hospital, offices, urbanizations, etc.).

In short, there is a clear difference between FTTH and the rest since it takes the network to the final point within our home. In contrast, the rest use coaxial cable terminations ( HFC ) from an issue (more or less far from the Building) to the connection point, therefore using electrical signals and thus being more susceptible to interference.

This is the best known and used classification, although there are other classifications:

Types of Fiber Optic According To Cable Mode

• SMF. Single-mode fiber or Single-Mode-Fiber has a diameter between 8 µm and 10 µm. It only allows one mode of transmission (parallel to the axis of the thread), so it can transport signals over a very long distance, at high speed, and without suffering just attenuation. They are yellow (OS1 and OS2).
• MMF. Multimode fiber or Multimode-Fiber has a diameter between 50 µm and 62.5 µm, and it can transmit multiple rays of light simultaneously since, having a larger diameter, the light can bounce at different angles. It is generally used for short distances from fiber cable or patch panel connection to equipment. They are orange (OM1, OM2) and blue (OM3, OM4).

They are not used to connecting long distances, about 2 km.

Types of Fiber Optic Depending on The Transmission Mode

• Simplex. Composed of fiber and a connector at each end
• Duplex. They are composed of 2 fibers and two connectors at each end. Each thread is marked “A” or “B” or uses different colored protective covers to differentiate itself.

As we can see, there are many classifications and types of an optical fiber according to the cable, transmission, material, etc. Still, the most used sort is according to the termination of the wiring, and in this sense, we have shared fiber and dedicated fiber.

Shared Fiber

Shared fiber is the one that offers the highest speed and is, therefore, the one most used by most Internet Providers. 

As we have already pointed out before, we refer to FTTH (Fiber To The Home). We find different structures since various infrastructures or Internet Links are based on Fiber Optic in the shared fiber optic models.

Links Based On Shared Fiber

The most common links in Shared Fiber are FTTH and HFC, as we have already mentioned before.

ENLACE FTTH (FIBER TO THE HOME)

This type of link allows the most direct, fast, reliable, and secure way to connect to the Internet since it connects each of the points or nodes between the central office of the Internet Provider or distributor with the home or office. This link allows a direct connection to the client or user.

With this type of connection, we can ensure a good download speed download velocity but not upload speed.

ENLACE HFC (HYBRID FIBER-COAXIAL)

As we have already pointed out before, in this type of link, the connection is not direct but rather connects through an intermediate node that reaches its destination (home or office) through a coaxial cable.

They connect the zone nodes with the central, but a coaxial cable starts from the zone node, combining two connection sections: optical and coaxial. These connections that use two lines are usually more affordable, but they are more susceptible to electromagnetic interference.

SYMMETRIC FIBER OPTICS

Symmetric Fiber has been an advance for Internet browsing. This kind of connection is now a trend and is increasingly used.

Symmetrical optical fiber allows the user to have the same upload speed as the download speed in the Internet connection.

It was given greater importance when contracting the Internet at the download speed (download). With the standardization and use of different applications, social networks, etc., the same matter is beginning to be given to the rate of uploading files, photographs, videos, etc.

Dedicated Fiber

Dedicated fiber is a type of fiber optic for an Internet connection so that it arrives directly from the Provider to the client without divisions or intermediate cables. This allows the client or user to be assured that the relationship will not be interfered with by third parties, nor will it be reduced.

This type of fiber allows interconnection solutions with high demand that require higher bandwidth.

HOW DEDICATED FIBER WORKS

The dedicated fiber will be simple or not its implementation depending on the geographical situation. For this reason, it is especially recommended for special privacy needs.

It is a type of fiber optic indicated above all for Companies, Offices, and administrations. Above all, they wish to interconnect their different delegations and equipment with a fluid connection and high transfer capacity, privacy, and storage.

Different Types Of HDMI Connectors

Different types of HDMI connectors have remained as it is after their initial introduction. This is very important, as it has allowed us to maintain backward comparability with all the HDMI standards coming after the first ones.
Backward comparability is which allows us to connect various different HDMI connector types through smart HDMI switches. These switches allow you to switch between different connector types seamlessly, and also lets you connect one HDMI port to multiple HDMI connectors. Check out Kinivo 550BN, which is the best-selling HDMI Switch.
The standard HDMI connector has 19 pins, and this standard is kept the same in every connector to allow for backward and forward comparability.
Here are all of the HDMI connector types explained.

Type A

This is the first-ever launched HDMI connector and is considered the main standard since then. This connector is still the most common one, and it is usually used on old AV systems, DVD players, TVs, Game consoles, and lots of other equipment. This connector is a bit larger as compared to the rest, and can be used on equipment on which space isn’t an issue.
The standard type A HDMI connector has 19 pins in total. It has enough bandwidth to easily handle SDTV, EDTV, HDTV, UHD, and 4K signals.
So, the type A HDMI connector is one of the most commonly used types of HDMI connectors.

Type B

Type B HDMI connector was also released alongside the type A connector. This connector is capable of transferring dual DVD-I signals. However, this connector was never widely used in products. That’s because HDMI 1.3 helped in increasing the speed of a single link beyond that of a double link. Another reason why this connector wasn’t widely used is that it is larger as compared to the single link connector. This leaves us with no reason to use this connector.
The type B HDMI connector has 29 pins, and six differential pairs instead of six, as in a single link connector (type A).

Type C

The type C HDMI connector is actually a micro HDMI, as it is smaller as compared to the standard type A HDMI connector. However, this connector still has the same 19 pins as in the type A HDMI connector. In terms of functionality and performance, type C and type A are almost at the same point. But the connector is very small as compared to type A.
The mini HDMI or HDMI type C was introduced alongside HDMI 1.3, as the need for a smaller connector arose due to the wide adaptability of HDMI connectors.
The shape and configuration of the mini HDMI have some changes.
You can actually use a Tube C HDMI in a Type A HDMI port, but you’ll have to use a type C to type A adapter.
These connectors can be seen on most of the portable equipment use carry around these days. For example, this is common on DSLR cameras, sat nav systems, and many other types of modern equipment.

Type D

The Type D HDMI connector has a shape like the micro USB connector. That is also the reason why this connector is known as a micro HDMI. This type of HDMI is very small, and yet it retains the same 19 pins used in HDMI type A, 1.3, and Type C. But just like HDMI type C, the pin pairings are different as compared to Type-A.
Type D, of Micro HDMI, was released alongside HDMI 1.4. This connector was made to make audio and video connectivity possible in smaller devices like mobile phones.

Type E

You won’t see HDMI type E in most of the tech products, as it is mostly meant to be used in vehicles. Type E was also introduced alongside the release of HDMI 1.4 and Type D.
This connector has a locking mechanism that prevents it from vibrating out of the port. There is also a shell present around the connector in order to keep it safe from dust and dirt.
With the help of fire modifications, you can actually use this connector to connect your vehicle with an external item.

Make Vs Female Connectors

• When it comes to identifying male and female HDMI connectors, you should keep in mind that the female connector is connected to the source of the signal or power, and the male connector is connected to the item receiving the power or signal. That’s because the pins on a female HDMI connector can’t be shorted by an external metallic object. But most of the modern HDMI connectors also save their male sides from short circuits.
• Female connectors are present on both the sending and receiving device, and a cord having two male connectors, one at either end ends, is used to connect both of the devices.
• One of the main reasons for this is that both of the devices connected together are usually exchanging data. Even the receiving device has to send some signals back to the sending device. This gives us the perfect reason to have female connectors on every device, and the male connectors on the wire used to connect both of the devices.
• Although the female connectors are usually recessed into the device’s body, they can still get damaged because of the stress caused by pulling the wire in the wrong way or something else. So, you’ll be shocked to know those female HDMI connectors sell more as compared to male connectors as they are easily broken.
• Also, if you have a wire with two broken HDMI connectors at either end, the cost of buying a new wire is actually lower as compared to the cost of repairing the broken connectors.
