Optic Connectors Challenging Copper in I/O Applications By Aarkstore Enterprise

Copper cables have historically been the primary media that allowed electronic systems to communicate. Copper cabling systems have evolved over the years to enable increasing bandwidth as system speeds increased. Cable constructions including coaxial, and shielded twisted pair along with advanced signaling devices have pushed the performance capabilities of copper Input / output cables to multigigabit speeds. Prediction of copper bandwidth limitations has consistently proven inaccurate as designers find ways to enable copper links to satisfy their performance requirements. Copper cable assemblies are an established technology that permits easy repair in the field using common tools. A variety of industry standards define copper interfaces that enable equipment connectivity, an essential feature of many of today’s electronic products.
 
 The elements of optic communication technology have been developing over a long period of time, but the ability to fabricate optic links became practical in the 1960’s. Copper cables have been in a continuous process of evolving to higher speed performance, while fiber was born with bandwidth capability far beyond the limitations of copper. Glass fiber was quickly adopted as the media of choice for long distance communication links that spanned the earth. Low cost, high bandwidth optic cables have enabled global telecom and Internet communications that have reshaped the world. In addition to exceptional bandwidth, fiber links offers excellent signal integrity, electrical isolation, noise immunity and the ability to transmit over long distances without the need for amplifiers or repeaters.
 
 A primary impediment to the implementation of fiber is the fact that signals produced by electronic equipment must be converted to optic pulses before they can be transmitted over fiber cables. This has been an expensive process that could only be justified in long distance applications. Improvements in the performance of optic cables together with the introduction of lower cost electro-optic conversion devices have allowed fiber to become competitive in shorter reach applications.
 
 Market demand for higher speed links is putting pressure on copper cables that must incorporate more exotic features to keep pace. Increasing data rates can limit the effective length of copper cable assemblies opening the door to optic alternatives. System designers now have the option of choosing optic or copper media in many I/O applications of less than 10 meters.

how sound signals are converted into electro magnetic signals for communication through fiber optics?

Now-a-days tele-communications are using fiber optics to send signals. But what is the mechanism behind the converstion of sound waves into light waves?

Light is just another part of the electro-magnetic spectrum, the same as radio waves. The light waves can be modulated and demodulated, either analog or digital, in the same fashion as other radio waves that bring you AM and FM radio as well as television.
