What is WDM?

multiplexing the wavelength of division or WDM is a signaling process that uses the use of laser technology as part of the communication protocol. The foundations of this process include a combination of several signals that are transmitted along the laser beams. Each of the signals is set to different wavelengths and is transmitted by fiber optics. Specialized filters at the reception point help to convert laser -controlled multiplex signals into a mold that can be processed into a feasible signal.

Although somewhat similar frequency multiplexing processes, multiplexing the wavelength does not use standard radio frequencies to configure various signals. Instead, the method converts signals to infrared wavelengths that are part of the electromagnetic spectrum. Together, the signals move through the fiber optics network and are segregated at the moment of termination. At the same time, the signals are converted into their original form, allowing the receiver to correctly interpret the signal correctly.

While the basic process of multiplexing wavelength division has the same for many years, the ability to use this process thanks to improvement in technology. At once, more than two infrared channels could not be used at the same time using optical cables. Although more efficient than previous communication methods, it has rapidly shown that this process can be upgraded to allow multiple channels to be used. This was achieved by adding additional filters that could work at the end of the segregation and direction of multiple signals at a time.

The use of multiplexing the division's wavelength today has reached a point where the integrity of the signal is extremely high, so they carry audio signals across the network in this way Currently clean at both ends of the connections. Further research is currently being carried out to improve the way in which the multiplexing of the wavelength division uses the electromagnetic width of the band within the communication process.Emphasis is placed to allow the method to carry other signals and at the same time maintain the current standards of clarity.
