1 petabit of data per second Today, the fastest fiber-optic cable speed available in a commercial gigabit network service is 10 Gbps. The Japanese business NTT reported the fastest fiber-optic cable speed ever recorded in 2012: 1 petabit per second. This represents one billion bytes of data transmitted over one single fiber strand of cable.
That's a million megabits -- or 250 gigabytes -- transmitted every hour. That's more than the entire content of Wikipedia transmitted in just under three minutes. It's also enough data to take about 15 hours to download at our current average of 3 million bits per second.
The record was set by using eight different wavelengths of light carried on a single fiber strand. Each wavelength can carry up to 9.065 terabits per square meter, which is more than enough capacity for an end-user connection. However, since these wavelengths are spaced very far apart, they require a very broad range of operating conditions to be successful. For example, if there's even a small amount of water present between the fiber and its protective casing, it could cause errors by mixing the wavelengths.
The main advantage of fiber optics over traditional copper wires is their ability to transmit data faster. Fiber-optic cables can reach speeds of up to 100 times faster than the next best option, while consuming less power along the way.
500 Gbps (gigabits per second). For the first time, data has been delivered at 500 gigabits per second across a single wavelength channel over a fiber optic network. This rate is 100 times faster than the previous highest rate of 50 megabits per second.
Fiber optics have revolutionized telecommunications by offering extremely high rates and low error rates. Optical fibers are thin strands of glass or plastic that transmit light through transmission lines. They can carry an optical signal containing many millions of bits of data between two points on a link. Fiber optics are used in telephone networks, cable TV systems, and global communications networks like the Internet.
Optical signals are transmitted using laser diodes called "drivers". The driver converts digital data into an optical signal which is then propagated down the fiber-optic cable to another laser diode called a "receiver". When the receiver receives the signal, it converts it back into electrical form.
The maximum speed at which data can be transmitted over fiber optic cables is limited by several factors. The most significant limitation is derived from the fact that fiber optics are designed to transport only certain wavelengths of light. Any other wavelengths may travel down the fiber but will not reach their destination. The term "chromatic dispersion" is used to describe this behavior.
Fiber internet is often the fastest sort of internet. However, several cable companies have recently installed DOCSIS 3.0 technology to allow for greater rates. Several cable internet service providers provide internet speeds of up to 940 Mbps, while Xfinity offers gigabit service with rates of up to 2,000 Mbps.
In addition to faster internet speeds, fiber also provides a clear connection with no delays. This is especially useful for online gamers and streamers who need a stable connection to avoid lag time or buffering that can affect their experience.
Fiber optic cables are much faster than traditional copper wires used by other ISPs. It's because they use light waves rather than electricity to transmit data, which allows for higher speeds and less delay. Also, since there's no noise associated with copper wire, it's suitable for voice over IP (VOIP) applications like Skype, but not always for video conferencing.
Because fiber optic cables are capable of transmitting millions of bits of data per second, it's recommended by broadband experts that if you can afford it, go with this type of internet connection. Not only will you get fast speeds, but you won't experience any downtime due to storms, floods, or other events that could damage copper wiring.
Fiber optic cables are available from your local phone company or cable TV provider. You may have to talk with them about signing up for an account with them first, though.
However, as Ethernet cable technology has progressed, Ethernet connections may now give speeds comparable to fiber optic lines. Optical fiber is normally quicker than copper Ethernet connection and has the potential to be extremely fast. However, optical fiber cables are more expensive than regular Ethernet cables and less ubiquitous.
Ethernet is a local area network (LAN) protocol defined by IEEE 802.3 in 1982. It is a layer 2 media access control (MAC) protocol that uses DIX binary arithmetic coding for transmission. The physical layer specification defines electrical and mechanical requirements for connecting stations. It does not specify a particular transmission medium such as wire, radio wave, or light beam. A variety of transmission media can be used for physical connectivity including twisted pair, coaxial, fiber-optic, and wireless methods.
Copper cables with RJ45 connectors are commonly used for computer networking applications because they are low cost and easy to install/remove. However, these cables are only capable of transmitting data at rates up to 1 Gbit/s. For higher rate communication, fiber optic cabling is required.
Fiber optic cables consist of thin strands of glass or plastic surrounded by foam or other material for protection and strengthened by steel or nylon fibers. Fiber optics transmit information by altering the intensity of light beams rather than using electric currents like conventional cables.
Fiber optic communication is more rapid. Copper-based transmissions are now limited to 40 Gbps, but fiber optics can transport data at almost the speed of light. In truth, while the bandwidth constraints imposed by fiber are mostly theoretical, they have been tested to be quantifiable in hundreds of terabits per second. One bit transmitted over one foot of fiber will lose about 1% of its signal strength.
Fiber is much harder to damage than copper. A sharp knife or cutting tool can slice through fiber with little effect, while breaking a copper wire can cut off blood flow to parts of the brain responsible for reasoning and judgment. Fiber optic cable is also less likely to cause interference with other devices. Radio frequency (RF) signals carried on copper cables can interfere with wireless communications equipment, but fiber does not transmit RF energy so it cannot cause interference when it works properly.
Fiber is less affected by electrical storms and earthquakes. These events can cause voltage fluctuations on copper wires that can change the state of bits stored in memory cards or computers connected to them. This problem does not apply to fiber, which cannot be electrically activated or inhibited like copper. It is also less vulnerable to lightning strikes. The streak of electricity across a cloud layer can reach down into a copper network and destroy cables, but fiber remains unharmed because it is not conductive.
Fiber is immune to electromagnetic pulses (EMP).
