Fiber optics is a type of technological data transmission that generates pulses of light through a very thin thread of transparent material that can be made of glass or plastic. It is widely used today and its main advantage is the speed at which these pulses of light travel, generating a very fast Internet connection.
It is one of the advances of the most important technology produced in the last decade. With this system, the signals they emit can travel long distances and can transmit data along their path. Its fibers can be single mode or multimode.
Through our study we made of this topic We want to teach you all the aspects that you have to take into account when choosing this technology for your communication with the Internet.
What are the main advantages of FTTH over other Internet connections? Is the best?
The FTTH (from English “Fiber To The Home”) It is a technology that is based on the use of fiber optic cable and systems adapted for this technology that contribute to the distribution of advanced services. For example, him triple playIt is nothing more than high-speed broadband Internet with fixed telephony and television on the same cable.
These features allow to get very high speeds navigation without interruption or variations that result in a multimedia service without alterations.
Another point that we can highlight as a great advantage of fiber optics is that several electronic devices can be used at the same time without losing the strength and quality of the Internet signal or other service provided by the provider.
If we compare it with another Internet system we will realize that its installation is much easierhas a direct connection to the central offices of the provider companies, the fiber optic cable is thinner than the coaxial cable and they provide services 24 hours a day without congestion.
Many people choose this technology because the videos and sound are more in real time, It has strong compatibility with real technology and has high resistance to heat, cold and corrosion..
Based on all these advantages it offers, we can say that fiber optic technology is the most suitable for all people who want to work from home and for those companies in which a connection without variations is needed.
Types of fiber optics What rates can be contracted and how are they different?
It is essential that you know the different types of fiber, since each one has its particularity. We explain some technical details below:
symmetric fiber
It is that technology in which equalize upload and download speeds predict these two parameters will always have the same data download and upload speed.
Many people think that symmetrical fiber is faster, but in reality it has nothing to do with one thing, many times depending on the cable operator, and they give more speed because they have a marketing interest and not because of a technical limitation.
Always we have to analyze this situation according to the real needs that we have in our homes or in the company in which we use a similar technology.
asymmetric fiber
This fiber optic technology also refers to each of the upstream and downstream data transmission connections, being the download speed greater than the speed we have to upload.
This type of service provided by providers has a significant difficulty since they are often slower than symmetrical fiber optics.
Dark Fiber
The dark term refers to those optical fibers in which the totality that was deployed is not being used, that is, it refers to the part that it is not illuminated.
It is estimated that in Spain there are around 2.5 million km of fiber deployed throughout the country, with approximately 30% being dark.
fiber prices
Once we have already analyzed each type of optical fiber that exists, we want to mention the best symmetrical fiber prices that we have found in the market so that you can decide which one best suits your convenience (In the previous table we show you the average speed that Spain has with respect to other countries)
As a clarification we want to tell you that we do not mention or analyze the asymmetric type since they would not be convenient for you financially. Take a look at the following approximate price list:
- “MORE MOBILE” offers a speed of 600 Mb with unlimited calls at a price of €29.99 for the first three months.
- The company “Yogo” It has a speed of 100Mb on offer at €32 per month with fixed telephony included.
- While the companyJazztel” They have among their wide range of products a 50 Mb fiber optic service plus fixed telephony for €40 during the first three months.
- Another offer that is interesting is that of “Orange”offering a 100 Mb fiber optic speed for €30.95, but if you want more speed they can offer you their 500 Mb product for only €45.10 per month.
- “Movistar” It has a 100 Mb service for €32.30 per month.
- The company “Vodafone” provides a 100 MB service at €32.50 per month, including telephony.
FTTH connectors What types are there and how much do they influence the performance of the connection?
fiber optic connectors arose from the need to quickly and efficiently connect and uncouple cables compared to if they had been done with a splice. I have a great advantage which is that it does not lose quality of the data transmission service.
There are four types of connectors that we can find on the market. Next we will talk about each of them:
Subscriber Connector
Commonly called SCit is mainly aimed at single-mode optical fiber and has a push-pull coupling, providing greater advantages for those analog CATV, GBIC and GPON cables.
Lucent Connector
You’ll find this type of push-pull connector with the name of LC, this element has a small format and is used with a 1.25 mm ferrule, which is half the size of the one mentioned above. It is highly required for those connections in which a high density is needed.
straight tip
This type of connector is refers to the so-called ST in the market of technological elements. It can be confused with the FC (which we’ll talk about next) but it has a bayonet mount that is used instead of a thread.
Ferrule Connector
Known as FCit is similar to ST, it is used for single mode optical fiber while maintaining polarization, a screw type aspect with a 2.5mm ferrule, it can be used with ceramic ferrules.
The importance of the description of these connectors is necessary to be able to distinguish them and thus place the correct one so as not to have problems in the future with variations in the Internet connection.
What is a “polish” in fiber optic connectors and how many are there?
Polishing the installation process of an optical fiber is Necessary as a requirement for good performance in data transmission, trying to keep the insertion loss as low as possible. To evaluate the quality that exists in the fiber optic connection, it is necessary to measure the parameters once the polishing has been carried out.
There are four types of polishing that are performed on fiber optic connectors, they are:
flat polished
Which is done manually and is used in multimode fibers. Their connection is based on a flat surface and when they are facing each other a small air space is formed which presents small imperfections generating return losses, with this kind of polishing we avoid the slightest imperfect surface.
polished PC
His name refers to Physical Contact It is used for both single mode and multimode fibers.. The ferrule comes with a concave spherical pre-polished, the most common connection with the PC connector which meets the two fibers the same as the flat way but the surface will be slightly polished in the curves which thus eliminates the gap of air.
Polished UPC
This ultra polished PC, It has the same features as the PC but they are used for single mode fibers where their surfaces are polished with a better finish.
APC polished
This kind of Polishing comes from the abbreviations for angled physical contact in which the surfaces with the connector are curved and also have a 8° angle, in this way they prevent the reflections that the light transition has from returning to the nucleus that the fiber has. Then the return loss increases to values greater than 60 db. For this kind of polishing, it is necessary to work with those fibers where their core is small.
FTTH cables: what types are there and how do they influence the performance of the connection?
Although up to now we have been talking about two kinds of cables, the singlemode and multimode. We can add one more variety, Plastic Optical Fiber (POF) but we won’t cover it in this article.
Next, we will detail the most outstanding specifications of each of the first two cables:
single mode cable
This type of cable is a fiberglass that has a diameter from 8.3 to 10 microns providing a single mode of transmission. It generally has a narrow diameter which propagates 1,310 or 1,550 nm.
Although its load is greater than multimode fiber, but it requires a light source that has a narrower width, it is crazy about its spectral aspect. Data is generally sent as multi-frequency.
Multimode Cable
fiber optic cable multimode has a broadband with more speed that oscillates between 10 to 100 Mb. The light waves that the transmission has are dispersed in several ways or what we call mode, they normally travel at 850 or 1,300 nm.
