A fiber optic bandwidth communication system, discovered in 1970, has created a quantum leap in communication protocols. It has also ushered in the Information age. It process involves sending signals via a fiber optic cable from one point to another.
The fiber optic signal is basically a pulse of light. The pulse forms an electromagnetic carrier wave. This wave is modulated to carry information. The process of transmitting information via fiber optic cables involves creating an optical signal using a transmitter, relaying the signal along the fiber, ensuring that the signal is not distorted during transmission, receiving the signal with a receiver and converting it into an electrical signal.
One perceived advantage of fiber optic cable technology is that it can be used by telecommunication industries to transmit telephone signals, Internet communications and cable television signals. It is distinctly preferred to copper wire in long distance and high demand applications. On the flip side is the fact that the infrastructure development for this technology is time consuming and complex. They are also currently expensive to install and operate. However, with the development of the technology the prices are expected to take a nose dive in the future.
Large businesses that have high volume data transmissions and long distance transmissions see immense value in the use of oc48 bandwidth fiber optic technology for data transfer. The costs are offset by the benefits of the application. Companies like AT&T offer fiber optic communications for delivery of a variety of high throughput data and broad band services to consumers.OC48 Bandwidth offers such a solution fro high bandwidth users.
The modern optic fiber high bandwidth broad band communication system consists of several parts. The most visible part is the transmitter and receiver located at the client premises. The transmitter converts an electrical signal received from the computer into a light signal or optical signal. This is then pushed into the optical cable that contains bundles of optical fibers. This cable is routed through underground conduits and buildings to the destination. Amplifiers along the way amplify the signal and ensure that “noise” does not distort the signal. The receiver located at the other end receives the signal and converts the light signal into an electrical signal that can be read by the computer.
Broadband companies that use optical fiber for providing high bandwidth communications such as oc48 to large businesses exploit the wavelength division multiplexing (WDM) feature of the optical fiber transmission. Wavelength-division multiplexing is the capacity of the optical fiber to add new channels and transmit new wavelengths of light through the channels. A bit of hardware called wavelength division multiplexer is built into the transmitter for this purpose. Similarly a wavelength demultiplexing device is built into the receiver at the other end. The optic fiber cable can transmit data in the range of 14 terabits per second through as many as 160 channels.
The transmission distance is limited only by attenuation and dispersion. Dispersion is the spreading of the optical pulses as they travel across the fiber. This dispersion is caused by a multitude of factors such as differences in axial speeds, intermodal dispersion and a host of other technical issues. Attenuation is the gradual loss of intensity of the signal. Engineers make provisions and allowances for these factors while designing high bandwidth lines for commercial use.
High bandwidth such as oc48 bandwidth through fiber optic cables has come to stay. The future of the connected world lies in the growth of this technology. More and more large businesses will find this technology the answer to their transmission problems.
