Fiber optic cables enable our dream of integrating all our cellphone, Internet and TV services. Fiber's broad bandwidth makes this possible. It provides more than sufficient capability to meet all our voice, information and video necessities.

The transformation from copper to fiber is tremendously accelerated by the invention of optical fiber amplifiers. Optical fiber amplifiers enable optical sign transmission over very long distances without the costly process of conversion to digital alerts, digital amplification and the conversion again to optical sign again as in traditional regenerators.

Today a lot of the community site visitors switching are still performed by electronic switches such as these from Cisco. But large curiosity and effort of using all-optical units for all network switching are accumulating within the trade. The most essential characteristic of all-optical switching lies in its nearly unlimited transmission capacity.

However, it's still within the prototype stage for controlling light with gentle, so optical swap circuits are nonetheless controlled by digital circuits at this second. The switching matrix could also be optical circuits but the control are nonetheless accomplished by electronic circuits.

Optical fiber is sort of the ideal medium for signal transmission obtainable today and in the foreseeable future. The glorious attribute of optical fiber is its immunity to electromagnetic interference. Optical circuits may be crossed in a common area without cross interference among them.

But there are problems that are impeding the speed of all-optical system growth. The most evident and primary cause is the compatibility necessities with legacy fiber optic methods.

Another huge benefit of optical fiber lies within the ability to multiplex its capability by way of WDM (wavelength division multiplexer). WDM modulates each of a number of knowledge streams into a different a part of the sunshine spectrum. WDM is the optical equal of FDM (frequency division multiplexer). The use of WDM can enhance the capability of a single channel fiber optic communication system by lots of of occasions.
