Fiber-optic communication

Fiber-optic communication is a form of <a href="/facts/Optical_communication/gshoNBto">optical communication</a> for <a href="/facts/Data_communication/1yAhaANd">transmitting information</a> from one place to another by sending pulses of <a href="/facts/Infrared/44XdJNcc">infrared</a> or <a href="/facts/Visible_light/jeofpMn4">visible light</a> through an <a href="/facts/Optical_fiber/5ruuIFbj">optical fiber</a>. The light is a form of <a href="/facts/Carrier_wave/ae98pBlY">carrier wave</a> that is <a href="/facts/Modulated/aAXPjINv">modulated</a> to carry information. Fiber is preferred over electrical cabling when high <a href="/facts/Bandwidth_(computing)/lY6Tb4gX">bandwidth</a>, long distance, or immunity to <a href="/facts/Electromagnetic_interference/gv3DlKNr">electromagnetic interference</a> is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.
Optical fiber is used by many telecommunications companies to transmit telephone signals, internet communication, and cable television signals. Researchers at <a href="/facts/Bell_Labs/fKP5Gk0H">Bell Labs</a> have reached a record bandwidth–distance product of over 100 <a href="/facts/Petabit/n45aTGHt">petabit</a> × kilometers per second using fiber-optic communication.[better source needed]
