Why Internet Speed Increases When Optical Fiber Cable Is Used?
Your internet is one of these three – Cable, DSL or Fiber. Because no one uses dial-up anymore. They do the same thing which provides you with internet access but they have their advantages and disadvantages. So, without further ado, let’s get right into it. Cable internet is a type of connection that transmits data through a cable television network through a coaxial cable while the cable is generally faster than DSL. Its primary disadvantage is that you are sharing bandwidth with neighbours who are using the same cable line so, during peak times, where a lot of people are online, your speeds are going to slow down considerably.
But, on the upside, cable internet speeds are not affected by how far you are from your ISP or Internet Service Provider. DSL stands for digital subscriber line it is a type of connection that transmits data over a telephone network through a telephone cable. DSL is the most popular connection in the world. Over 60% of broadband connections are DSL. Unline cable DSL bandwidth is not shared. But, on the downside DSL Internet speeds are affected by how far you are from your ISP. So, the farther you are, the slower your speeds. There are two types of DSL, connection asymmetric and symmetric.
Asymmetric offer higher download speeds than upload speeds while symmetric offers equal download speeds and upload speeds. Fibre-optic communication is the future of data transmission. Data is transmitted through plastic or glass wires as light waves fibre optics offer the most potential for high-speed data transmission and it’s the clear solution for our growing bandwidth needs. Its main disadvantage, however, is that fibre is expensive to install which is the main reason why it’s still not very widespread today. Now let’s go over to what matters. And, that is the speed.
If you want to know more about internet speeds. DSL will give you between 128 kilobits per second to 24 megabits per second download speed. But speeds are constantly being upgraded like at the recent broadband world forum in Amsterdam. Where companies announced that DSL speeds will be boosted to one gigabit per second in 2016. Cable internet, on the other hand, will give you speeds of upto 150 megabits per second and download speed. However again this is shared bandwidth. So, during peak times, you are going to get much slower speeds like DSL cable internet providers are looking to provide Gigabit Internet in 2016.
Fibre is really fast. Well, DSL has yet to achieve gigabit internet speeds, fibre already has Google Fiber is an internet and TV service that gives you speeds of one gigabit per second download and one gigabit per second upload. That’s 1000 megabits per second download and 1000 megabits per second upload with gigabit internet. You can download a whole album in one second, you can download a one-gigabyte file or upload your one gigabyte YouTube video in 8 seconds.
But, fibre doesn’t end there, researchers have achieved speeds of 255terabits per second which is about 32 terabytes per second with that kind of speed, you can download a 1-gigabyte file in 1.25 microseconds. But, 255 terabits and gigabit internet are far from being a commercial product like long – long-term as of now, Google Fiber is only available in 8 locations in the whole world. But this is something to look forward to the applications of fibre optics are not limited to the internet. They also include telecommunications cable, TV and electricity transmission.
Is It Possible To Hack A Optical Fiber Line?
In today’s world hackers can easily obtain these kinds of fibre tapping tool online, quite easily. And be able to watch a few out to YouTube video’s to learn how to hack fibre optics and get access to sensitive data. What we will learn today is using a very conventional standard optical network system where we have a video source. Where the video is mapped and encoded over a 10 Gigabit Ethernet signal. Similar to signal that would be coming off of a standard router and that Ethernet signal going across and OTN fibre-optic networks and being decoded at the other end and the video being recovered.
So what we will be using as per that learning to complement this system is a fibre optic taps like the one we have got table behind. That fibre optic tap is sitting on the fibre and we are going to be using that as a tool for the hacker to get a copy of the optical signal to decode that optical signal and display the video stolen from the fibre over on this monitor. So, on the left, there will be the screen that the hacker would see and what another person will do is tapping the fibre and what we should see right now.
Video being extracted and within seconds by clamping that tool onto the fibre we can extract the video information in the real world this could be confidential data. This could be a patient record, this could be any sort of sensitive company information that would get stolen by the hackers. What we will now demonstrate is the use of an encryption system to prevent that theft of critical information. So what we will not do is reconfigure the system so that instead of having a standard optical network system that is unencrypted. We will reconfigure the network to use an encrypted network.
So, in this case, that another person is configuring the equipment to move away from a non-encryption card. To an encryption card and once that network is complete, the person should start and clamp the fibre onto the network. We will go back to the video interface and we will see that with the data now being encrypted, we do not see any video signals coming in. The tap is extracting the light from the fibre but because the signals are encrypted, that signal cannot be extracted and we see no video signals coming onto the network to protect against the theft of data on your optical network.
CNS portfolio offers a variety of security solution part of CNS 65 would converge packet-optical platform r2 cars. The first one being the 4/10 git OTR card. 100 gig and 200 gig wave logic encryption solution that protects the data across the network also part of CNS portfolio is our data centre interconnect platform. The wave server which now introduces upto 400 gigs of encryption capabilities in a 1 RTO chasis in today’s world with the amount of data that is being put over the network and the sensitive data that is being supported through cloud services and data centre environment.
No enterprise is immune to the ever-increasing threat and the sophistication those attacks over fibre optic networks to obtain sensitive and confidential information. Here what you have learnt is really how easy it information that is running across an optical fibre network and in reality, those hackers can go undetected. Stealing a massive amount of information on these networks.
Fibre optic broadband is four times faster than the UK average infinity. What you may not know is that most of this broadband is not truly fibre optic to understand why I will have to explain how broadband works. You get two types of broadband, the UK first provider over copper landlines. And, also resold by ISPs using the open reach network. Landline broadband works by electronically splitting the copper phone line into the channels one for voice calls and the other for broadband which is why you have that little filter on your phone line.
This is known as digital subscriber line or DSL. The type of DSL used in the UK for basic broadband is called a DSL or asymmetric DSL. This means that the download speed is faster than the upload speed. You can get upto 24 megabits per second download and about one more megabit per second upload. So, your line goes from your house either above or below ground to street camera to join large cable which goes to a telephone exchange. This cable is connected to a device called a DSLAM which gives you the broadband service.
The DSLAM is connected to the result of the network with Fibre uses a technology called DOCSIS which uses the MT electrical space, not used by TV channels to provide broadband over its coaxial copper cable, TV network cable. The TV is designed more for one-way communication so that upload speed is pretty low. Fibre uses thin strands of glass to trauma transmit data as pulses of light. Finally, you started around 1980 and every form of modern communication that you can use daily for making a phone call to sending a tweet.
It uses fibre somewhere with a line in fact over 95 per cent of all the world’s telecommunication traffic is sent via undersea fibre optic cables, not satellites as most people assume. The reason why fibres are popular is that it allows us to spend almost infinite amounts of data of extremely long distances.
Optical fibre is immune to electrical interference when people wanted faster broadband. Companies came up with two different approaches. If GGC five to the cabinet and the FTTH – fibre to the home.
Fiber to the cabinet words by effectively shorting the length of the existing copper wiring going into your home which is done by bringing the fiber to a new street cabinet which is placed close to the existing one for landline Warband is a DSLAM inside this new cabinet that uses VDLS to offer speeds of upto a hundred megabits per second download and 20 megabits per second upload. Many companies do the same thing by placing their electronic equipment in a vehicle cabinet.
The problem with FTTC is that you are using copper wiring that was meant for something else or maybe lower speed. These lines were installed years ago and were not designed for digital communication both ADSL and VDSL have distance limitations. ADSL can only work on lines at a list in five kilometres long VDSL has an even shorter reach of about one Kilometer. So, if you are about 500 meters from the cabinet, you will only get about half the advertised speed. DOCSIS doesn’t have the same distance limitations as VDSL but the network is shared so you might now get the advertised speed.
Especially during peak times. And, finally, we get fibre to the home FTTH for short which for some reason is called fibre to the premises in the UK. But, term FTTH is mandatory to be used here because that’s the one used internationally. Fibre to the home bypasses the old copper networks completely giving you into fibre connectivity. One of the criticisms of FTTH is that it’s expensive but it’s not the fibres that cost the most money upto 80% of the cost comes from the civil works, digging the earth and trenching getting the fibre into the ground. Now, fibre to the home is the best technology that we have available to deliver broadband.
If GGH works over longer distances in VDSL with a range of about 20 kilometres, Fiber to the home also has an almost unlimited capacity of upgrades as you are only limited by the electronics on either side. It’s also immune to electrical interference, one of the fibres of the homes, the biggest advantages is that it offers a much higher upload speed than most copper-based alternatives which is important today.
