Let’s get this started. Internet works on the fundamental principle of sending data in the form of electromagnetic signals through wires. Whether cable internet, DSL, or fiber internet connections, they all work by converting analog signals to digital signals and vice versa. Fiber optics send the light pulses(signals) one way, while regular copper wire sends them both ways. Fiber internet is faster because it does not have an electrical resistance that signs must surmount as they travel through copper wires.
How do you get fiber optics to work?
Fiber internet works by sending light pulses through glass or plastic fiber strands. Special lasers are used to generate light pulses with exact, nanosecond extended timings. Fiber optics are made of stalks of silica glass or even pure diamond. Each connection uses one strand, so fiber internet is “full-duplex,” which means it can send and receive signals simultaneously, unlike ADSL or Cable internet.
How does the signal get converted to light pulses and back again?
There are two ways of sending signals digitally through optic fiber. First, one is called time-division multiplexing(TDM), in which the computer sends data in the form of 1s and 0s encoded into short blips of light(microseconds long). The second one is called wavelength division multiplexing(WDM), in which the computer sends data as even more momentary blips of light about 100 attoseconds long each.
The computer sends 1s and 0s encoded into short blips of light (microseconds may be milliseconds, maybe nanoseconds) through optic fiber. The laser creates a beam of light that has two different wavelengths. The laser sends the 1s and 0s encoded blips of light by rapidly switching between the two wavelengths(attoseconds). Computer screens receive data as an electrical signal.
How is the internet connection upgraded to fiber optics?
ADSL, Cable, or Wireless internet connections convert analog signals to digital signals and vice versa. For example, ADSL converts analog signals received from telephone lines to digital signals so computers can send and receive data like a standard cable connection. The computer sends 1s and 0s encoded into short blips of light (microseconds may be milliseconds, maybe nanoseconds) through optic fiber. The laser creates a beam of light that has two different wavelengths. The laser sends the 1s and 0s encoded blips of light by rapidly switching between the two wavelengths(attoseconds). Computer screens receive data as an electrical signal.
How do you get an internet connection?
Well, first, we convert the signals into light pulses through optic fiber. Then we use those pulses to send them back to the laser, which emits those different wavelengths of light depending on whether it’s receiving 1s or 0s. Then depending on which signal (red light or green light) reaches the computer screen, either 0s or 1s are sent to the computer.
How does electrophorus work?
Electrophorus works by creating static electricity through contact with a special pad connected to an electrical generator. As you continue to rub the special place with the electrophorus, more and more static electricity is created until you can shock your friends or enemies.
Why does it work?
When you rub two objects together like electrophorus, one material loses some electrons that move towards another material, making both positively charged. One material has more protons than electrons, so it has a positive charge, while the other one has more electrons than protons, so it’s negative.
