Get to Know More about the Multiplexers

The key to maximizing or optimizing the use of the fiber is a WDM multiplexer or mux. At the heart of the operation, the Fiber multiplexer lies in gathering all the data streams together to be simultaneously transported over a single fiber. By combining multiple input signals after taking them. On to a common, single line output, it multiplexes them together. On a fiber pair or single fiber, the…

In communications networking fiber multiplexer is one of the most important components. From the network manager’s viewpoint, its central function is to concentrate many users on a single transmission channel so that it can maximize the efficiency of that channel: in almost every aspect of networking digital data, voice, and video it is used. This section will tell you about the advantages and disadvantages of different data multiplexing techniques, about why these different techniques were evolved to solve particular network engineering problems.

The bandwidth properties of optical fiber are very well known and they make it to the media of choice for high-speed data and video applications. However, to take advantage of this bandwidth various forms of multiplexing are required. The two most commonly used are time-division and wavelength division multiplexing. In fiber optics, we refer to attenuation as a transmission loss. It is the decrease in light signal intensity as per the distance covered by the signal in a transmission medium.

Multiplexer interfacing is not very much easy as it is for analog switches. To control multiplexer digital video manufacturers can write interfaces, although this is not commonly done.

Fiber adapter will allow the digital video system to display the output of the multiplexer like it were itself a video camera. When this is completed, it will become necessary to control the multiplexer, which can even be performed through the multiplexer’s data control input. Under a single remote keyboard command, maximum multiplex manufacturers make accessory products that can allow the networking of their multiplexers.

In two ways the available bandwidth can be used in a transmission channel: At first into a subset of frequencies fiber splitter divides the available bandwidth frequency spectrum. Secondly, for each channel, it allocates all the available bandwidth for a fixed discrete period. As an analog solution to multiplexing, FDM is primarily used, for example in telephony it has been used extensively; indeed many of the FDM standards and techniques such as the multiplexing ratios said by the early designs of telephone exchange multiplexers are in evidence in a few of the latter digital exchanges.

Different Components in DWDM System and its importance

In the development of fiber optic transmission technology, dense wavelength division multiplexing (DWDM Mux) is one of the most recent and important technologies. It can provide potentially unlimited transmission capacity and this is one of its most obvious advantages. There are four important components in a DWDM system, which are optical transmitter/receiver; optical amplifier, DWDM Mux/Demux…

Attenuation is known as transmission loss in fiber optics. Concerning the distance traveled, it is the reduction in light signal intensity by the signal in a transmission medium. To limit the transmission of a digital signal traveling in large distances, Attenuation is an important element. As it travels along with free space or optical fiber, an optical attenuator reduces this optical signal. The fiber splitter is very reliable.

When used in fiber-optic communications, Optical fiber attenuators may employ several principles. The gap loss principle is one common principle. To the modal distribution, Attenuators using this principle are sensitive ahead of the attenuator. Thus, they should be near or at the transmitting end or utilized. If not, then intended, the attenuators could establish less loss. By attenuators that use absorptive or reflective principles, this problem is avoided.

Basic three types of optical attenuator are there: the continuously variable attenuator, step-wise attenuator, and the fixed attenuator. By specific amount, Fixed attenuators reduce light signals with no or negligible reflection. Fixed attenuators are known for more accurate data transmission because signal reflection is not an issue. The voltage standing wave ratio, range, flatness over a particular frequency, peak and average power-handling capability, attenuation amount, size, performance over a particular temperature, and height are included in crucial elements associated with fixed attenuators. To enhance interstage matching in an electronic circuit, fixed attenuators are also often used.
