What is the roadm?

The reconfigurable optical multiplexer or roadm is a device used in many different optical networks. This type of multiplexer has essentially the ability to control the direction and focus of infrared and visible light emissions in the range of different wavelengths. It is unnecessary to convert these emissions into electrical signals, which must be turned back into its original form at the time of termination. Roadm is often used with any system that uses multiplexing wavelengths or WDM.

The foundations of the roadmm are relatively simple. Three operations take place within the operating process of this type of optical multiplexor add-drop. These functions are known as Add, Drop and Cut-Through. The visible or infrared outgoing signal that is generated represents ADD on the multiplexor. At the same time, the ability to end the reception of the incoming infra -red -reding. Visible light emissions is known as a drop. Cutting occurs when the beam passes through a multiplexer without anyIf the type of adjustment.

There are currently two similar roadm technologies that are commonly used. Wave length blocking technology is an older version of the roadm, which includes the initiation of the wavelength in the signal to adapt to the channel. This is achieved by filtering light emissions and extraction of data for inclusion in another issue to another wavelength.

Planar Lightwave Circuit is the second common form of roadm. With the PLC, the conversion process is still found in wavelength blocking technology, but is effective. This means less time to process the light signal, fewer additional devices needed to interact with the transport fiber, and therefore lower costs of operation.

However, it should be noted that no approach to roadm functions is a real optical branch process that it is not possible to direct a given beam of light to a particular port without joiningLika of key intermediate steps. At present, however, research is underway, which improves the improved version of the roadmm, which will be responsible for this and allow optical branching using multiplexor.
